Structure of linear servo motor

Linear servo motor has the primary side which consists of the iron core and coil, and the secondary side which consists of the

mounting part (yoke) and permanent magnet. (excluding coreless type LM-U2P_)

■Primary side

The primary side has the motor core with winding and is covered with the molded resin.

■Secondary side

The secondary side has the permanent magnet on the mounting part (yoke) and is covered with the molded resin or stainless

cover.

Magnetic attraction force

The secondary side of the linear servo motor contains a strong permanent magnet, so a magnetic attraction force (the force

by which a magnet attracts magnetic bodies) is generated toward magnetic bodies such as iron.

This magnetic attraction force is always acting regardless of linear servo motor power on/off.

side), and most of them do not leak to the mounting part (yoke) surface side for its structure.

Because of this, a magnetic attraction force occurs on the magnet face side of the secondary side, not on the mounting part

(yoke) surface side.

The permanent magnet used for the linear servo motor is very strong.

When an A4-sized iron sheet is fully attracted, the magnetic attraction force becomes as high as 2.5 t. Use abundance of

caution with the handling.

Magnetic attraction force = 400 [kPa]

For safety

The magnetic attraction force is in inverse proportion to square of the distance to a magnetic body, so it drastically increases

when the distance becomes small.

When mounting the secondary side of linear side motor, ensure the sufficient distance from the magnetic bodies around it and

securely fix those magnetic bodies.

CONTENTS

1 Handling of Linear Servo Motor

Precautions

• MR-J5-_G_-RJ and MR-J5-_A_-RJ will be available in the future.

The linear servo motor uses a strong magnet on the secondary side. Incorrect handling is extremely dangerous and may

cause serious accidents. Please read this chapter and thoroughly understand the contents beforehand, and handle carefully.

1.1 Design Instructions

• Although dynamic brake can be applied by the servo amplifier, the coasting distance becomes longer when the mass of the

moving part is heavy or when the speed is high. This is highly dangerous and may result in collision into the stroke end.

Install anti-collision mechanism such as an air brake, or an electrical and mechanical stopper such as shock absorber to

reduce the impact of the movable part. (No linear servo motor with an electromagnetic brake is available.)

• The magnetic attraction force operating between the primary and secondary sides is always in operation even when the

linear servo motor power is not turned on. As such, the machine must be designed with sufficient rigidity to support the

magnetic attraction force and maintain the accuracy.

• Since the running load by friction increases in proportion to the magnetic attraction force, arrange to reduce friction as

much as possible, such as installing the linear guide with high accuracy.

• When the linear servo motor is used on a vertical axis, a drop prevention system such as a spring and counter balance is

required on the machine side.

• Install the linear servo motor in such a way for the thrust to operates on the center of gravity of the moving part. When the

thrust does not operates on the center of gravity of the moving part, the moment occurs.

• If magnetic chips such as iron fragments or the like is present, it may stick to the permanent magnet on the secondary side

and cause malfunction. In such environment, take measures to prevent adsorption and penetration of magnetic chips.

• Oil proof and dust proof measures for the linear encoder is required, more so than for the linear servo motor. Contact each

linear encoder manufacturer for details.

• Do not hit the primary side against the stopper. The primary side may be damaged. Arrange for the table attached to the

primary side to hit the stopper.

• Do not use the screw holes of the linear servo motor for any purposes, other than for machine installation.

• For installation, use all the screw holes provided in the linear servo motor.

• When a dangerous condition is presumed at the time of stoppage and product failure, prevent it by providing an external

braking system for maintenance use.

• Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.

• Arrange for the primary and secondary side to satisfy the mounting dimensions.

• When using linear guide as base, check the specifications, and determine the processing accuracy. Contact each linear

guide manufacturer for details.

• Movable range of the linear servo motor should be equal to or less than the effective measurement length of the linear

encoder.

• For the stopper, use shock-absorbing material such as polyurethane rubber.

• In the condition where cutting fluid or lubricating oil are c

humidity, continuous operation of the linear servo motor for a long period of time may results in the deterioration on the

insulation of the linear servo motor. Provide measures such as oil proof, dust proof cover, and dew condensation prevention

to protect the linear servo motor.

• Arrange in consideration the installation work. For details of the installation, refer to the following and the "Installation"

section of each linear servo motor series.

Page 10 Instructions on installation operation

• For high-accuracy positioning, ensure that the machine to be as rigid as possible, and increase the mechanical resonance

point.

• To ensure the utmost rigidity of the machines, adopt an integrated structure to the base. When using bolts, etc. as fastener

is inevitable, use thick bolt with shorter neck size. Make the pitch dimension of bolt holes as small as possible.

• When loading works or others on the table, make the center of gravity to be as low as possible. Additionally, position of the

center of gravity should be between the two linear guides.

• Since the movement and accuracy of the machine may be adversely affected, arrange for the center of thrust of the linear

servo motor, and the center of gravity of the moving object, to be closer with one another.

• When the mounting rigidity of the linear encoder is not enough, the feedback signal may be disturbed by the machine

vibration, and the desired performance may not be satisfied. Furthermore, as the same condition also applies when the

linear encoder is susceptible to electric noise, arrange and install in such a way that would be unaffected by vibration and

electric noise.

• Establish a structure that can withstand high speed and high acceleration/deceleration.

1.2 Instructions on installation operation

Instructions on using lifting machines such as crane when installing the linear servo motor are shown below.

• The cables should not be damaged, stressed, loaded, or pinched.

• Install the linear servo motor on incombustible material. Installing them directly or close to combustibles will lead to smoke

or a fire.

• Prevent contaminants such as conductive foreign objects such as screws and metal pieces, and combustible foreign object

such as oil, from entering the linear servo motor.

• Linear servo motor may be hot depending on the operating method. Take safety measures such as providing covers.

• Workers installing linear servo motors and machine operators are not allowed to wear or carry electronic devices (such as

watches, calculators, personal computers), and magnetic recording media (IC cards, magnetic cards, floppy disks, and

others), closer to the secondary side. The magnetic effect may cause operation failure or malfunction.

• Securely fix the linear servo motor to the machine. If attached insecurely, the motor may come off during operation.

• Do not overtighten the eyebolts of the linear servo motor. Tightening too hard may damage the tap.

• Stacking in excess of the specified number of product packages is not allowed.

• Do not hold the cables or connectors when carrying the linear servo motor. Otherwise, it may drop.

• Install the linear servo motor in a place that can withstand the mass, in accordance with the user’s manual.

• When installing on the secondary side, use non-magnetic tools.

• Securely fix the linear servo motor to the machine. If attached insecurely, the motor may come off during operation.

• The moving direction of the linear servo motor and linear encoder must match. Otherwise, the linear servo motor may

operate unexpectedly.

• To prevent a connection failure, malfunction, or others, do not strike the connector.

• Use the product within the specified environment. For the environment conditions, refer to the specifications of the linear

servo motor series.

• To prevent rust, do not touch the linear servo motor with bare hands.

• The primary side and secondary side may be damaged by a fall or shock.

• Do not install and operate the servo amplifier and the linear servo motor which have been damaged, or with any parts

2 INSPECTION

Precautions

The linear servo motor functions as motor when mounted in the equipment (built-in). The IP rating is IP00. Perform the

following inspections and cleaning.

• The linear servo motor is structurally unrepairable. If the linear servo motor is damaged, it must be replaced.

• Do not disassemble and/or repair the equipment on customer side.

• Discoloration of the molded resin of the linear servo motor may occurs. Though the lost color may not be the cause of

malfunction, inspect the molded resin.

• If the magnet protective cover is stainless, it may be deformed or damaged if it is strongly pressed or a magnetic body is

attached to it. Take special care of the end part of the product, as it is easily deformed.

2.1 Inspections on primary side (coil)

Attachment of water and oil

Check that the primary and secondary side of the linear servo motor are not wet with water or oil. When the linear servo motor

is wet, the insulation on the primary side deteriorates, and may cause a malfunction. Establish the mechanical structure in

which water and oil are not attached to the linear servo motor.

Molded resin

Check the molded resin on the primary side for fragmentations, breakages, and cracks. If fragmentations, breakages, and

cracks are found, replace the primary side, as insulation have deteriorated and may cause a malfunction.

Scratches on the surface that faces the secondary side (magnet)

Check for scratches on the primary-side surface which faces the secondary side. If there are scratches on the primary-side

surface which faces the secondary side, replace the primary side. If scratches appear on the primary side due to a foreign

matter caught in the empty clearance between the primary and secondary side, remove the foreign matter, and establish a

mechanical structure to prevent similar situation.

Looseness of mounting screws

Check for loose mounting screws on the primary side. When the mounting screws on the primary side are loose, tighten the

applicable screws.

Scratches and cracks on the linear servo motor cables

Check for scratches and cracks on the linear servo motor cables. If the linear servo motor cables have any scratches or

cracks, replace the applicable cables. Especially when the cables are moved, make inspections periodically.

Linear servo motor Linear servo motorServo amplifier Servo amplifier

LINEAR SERVO MOTOR

• Insulate the conductive parts of the terminals.

• The performance is not guaranteed if the specified servo amplifier and linear servo motor are not combined. If used with

unspecified combination, the servo amplifier or linear servo motor may be damaged or may operate unexpectedly.

• The equipment must be installed in the specified direction.

• Do not install or operate the linear servo motor which has been damaged or has any parts missing.

• Do not modify the linear servo motor.

• To prevent unexpected operation of the linear servo motor, wire the equipment correctly and securely.

• Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism. Otherwise, the

cables and connectors may be disconnected during operation.

• Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF(-H)) on the servo amplifier output side.

• To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier and the linear servo

motor.

• To prevent abnormal operation and malfunction, connect the servo amplifier power output (U/V/W) to the linear servo motor

power input (U/V/W) directly. Do not connect a magnetic contactor and others between them.

• To prevent a malfunction, do not connect AC power supply directly to the linear servo motor.

• When the wires are not tightened enough to the terminal block, the wires or terminal block may generate heat because of

the poor contact. Be sure to tighten the wires with specified torque.

• The cables such as the power cable deriving from the primary side cannot stand the long-term bending action. Avoid the

bending action by fixing the cables to the moving part or others. Also, use the cable that can withstand the long-term

bending action for the wiring to the servo amplifier.

• Use the linear servo motor with the specified servo amplifier.

• To prevent malfunction, eliminate static electricity before wiring, switch operation, or others.

• To prevent failure and malfunction, only the power/signal specified in the user’s manual should be connected to each

terminal.

• We recommend using HIV wires to connect the servo amplifier to the linear servo motor. Therefore, the recommended wire

sizes may be different from those of the used wires for the previous linear servo motors.

Installation of the secondary side (magnet)

Precautions

Plate

Secondary side to be a mounting standard

• When the additional secondary side is mounted after one has been already set, slide the additional secondary side to

mount it in its specified position after setting it away from the already mounted one as shown in this section.

• Keep the cumulative pitch error of the mounting screw holes to within ±0.2 mm. When two or more secondary sides are

installed, clearance may be left between the secondary sides depending on the installing method and the number of

secondary sides.

■Procedure

When using multiple secondary sides, arrange the name plates attached to the product in the same direction to keep the

layout of magnetic poles.

Then, mount them with the following procedure to decrease the clearance between the secondary sides.

1. Securely fix with bolts the secondary side to be a mounting standard.

2. Set the secondary side on the mounting face and fix it with bolts as temporary joint.

3. Press the secondary side fixed as temporary joint toward that to be a mounting standard.

4. Securely fix with bolts the secondary side fixed as temporary joint.

5 Linear servo motor

5.3 LM-H3 series

Installation of the primary side (coil)

Precautions

• It is recommended to install the primary side in the position free from the secondary side. When mounting the primary side

over the secondary side unavoidably, use the material handling equipment such as crane which is fully competent to

sustain the load of attraction force and others.

• When sliding the primary side to the secondary side after installing, be very careful with the attraction force that is

generated.

■Procedure

1. Mount a part of the secondary side.

2. Mount the primary side in the position free from the secondary side.

3. Move the primary side over the mounted secondary side. Confirm that the primary side does not contact the secondary

side.

4. Mount the rest of the secondary side. Confirm that the primary side does not contact the secondary side.

• When the additional secondary side is mounted after one has been already set, slide the additional secondary side to

mount it in its specified position after setting it away from the already mounted one as shown in this section.

• Keep the cumulative pitch error of the mounting screw holes to within ±0.2 mm. When two or more secondary sides are

installed, clearance may be left between the secondary sides depending on the installing method and the number of

secondary sides.

■Procedure

When using multiple secondary sides, arrange the caution name plates attached to the product in the same direction to keep

the layout of magnetic poles.

Then, mount them with the following procedure to decrease the clearance between the secondary sides.

1. Use bolts to securely fix the secondary side which is to be the mounting standard.

2. Set the secondary side on the mounting face and fix it with bolts as temporary joint.

3. Press the secondary side fixed as temporary joint toward that to be a mounting standard.

4. Securely fix with bolts the secondary side fixed as temporary joint.

Installation of the secondary side (magnet)

Precautions

Plate

Secondary side to be a mounting standard

• When the additional secondary side is mounted after one has been already set, slide the additional secondary side to

mount it in its specified position after setting it away from the already mounted one as shown in this section.

• Keep the cumulative pitch error of the mounting screw holes to within ±0.2 mm. When two or more secondary sides are

installed, clearance may be left between the secondary sides depending on the installing method and the number of

secondary sides.

■Procedure

When using multiple secondary sides, arrange the name plates attached to the product in the same direction to keep the

layout of magnetic poles.

Then, mount them with the following procedure to decrease the clearance between the secondary sides.

1. Securely fix with bolts the secondary side to be a mounting standard.

2. Set the secondary side on the mounting face and fix it with bolts as temporary joint.

3. Press the secondary side fixed as temporary joint toward that to be a mounting standard.

4. Securely fix with bolts the secondary side fixed as temporary joint.

5 Linear servo motor

5.5 LM-F series

Installation of the primary side (coil)

Precautions

• It is recommended to install the primary side in the position free from the secondary side. When mounting the primary side

over the secondary side unavoidably, use the material handling equipment such as crane which is fully competent to

sustain the load of attraction force and others.

• When sliding the primary side to the secondary side after installing, be very careful with the attraction force that is

generated.

■Procedure

1. Mount a part of the secondary side.

2. Mount the primary side in the position free from the secondary side.

3. Move the primary side over the mounted secondary side. Confirm that the primary side does not contact the secondary

side.

4. Mount the rest of the secondary side. Confirm that the primary side does not contact the secondary side.

5 Linear servo motor

5.5 LM-F series

Liquid cooling

LM-F series linear servo motor is compatible with liquid cooling. Configure the machine (system) after checking the following.

• Parts required for cooling system design, including the cooling pipe laying in the primary side table, parts required for

installation and cooling, cooling machine (chiller), and coolant should be selected by the customer. For example, when

water is used as coolant, 5 liter or more is required per minute. Keep the pressure on the pipe flow entrance to be 0.5 MPa

or less.

• To prevent any foreign matter from entering into the cooling pipe, be sure to always set the filter, etc. in the flow path.

• To avoid liquid leak, pipe laying for cooling and joint should be selected by the customer. Especially, select the cooling pipe

which stands the bending action.

• It is recommended to keep the liquid temperature injected into the cooling pipe around 20 °C. Although high cooling effect

may be obtained by lowering the liquid temperature, be careful about the dew condensation.

• Since the overload protection characteristics are different from that for natural cooling, check if the condition such as

operation pattern is matched with the overload protection characteristics. If the operation pattern is not matched with the

overload protection characteristics, an alarm may occur. For the overload protection characteristics, refer to the following.

• As the material for cooling pipe is copper, select the rust preventive material which does not corrode the copper.

• When laying the cooling pipe, fix the hexagon part of cooling pipe with spanner. Tightening torque should be 3.0 N•m to 3.5

N•m.

Installation procedure

Precautions

Secure the secondary side with the hexagon socket head cap screw.

Stage

Tool for fitting end-surface position or others

Temporarily fix the secondary side with the hexagon socket head cap screw, and secure the secondary side after fitting its end surface to the tool.

• When the additional secondary side is mounted after one has been already set, slide the additional secondary side to

mount it in its specified position after setting it away from the already mounted one as shown in this section.

• After installation, confirm that the primary side does not contact the secondary side.

• Keep the cumulative pitch error of the mounting screw holes to within ±0.1 mm. When two or more pairs of secondary side

are installed, clearance may be left between the secondary sides depending on the installing method and the number of

secondary sides.

■Step 1.

1. Place one unit of secondary side on the stage.

2. Press the side face of the secondary side to the stage, and securely fix it with the hexagon socket head cap screw.

3. In the opposite position of the secondary side that is installed in 1) and 2), press the side face of the secondary side

which is installed as the second one, and fix it with the hexagon socket head cap screw as temporary joint.

4. Using a tool for fitting end-surface position, fit the end-surface of the secondary side which is installed in 1) and 2) and

that of temporarily fixed one in 3), and securely fix the temporarily fixed secondary side with the hexagon socket head

cap screw.

*1 It should be prepared by the customer.

5.6 LM-K2 series

■Step 3.

Resinous non-magnetic sheet

Move the primary side.

Temporarily fix the secondary side with the hexagon socket head cap screw, and secure the secondary side after fitting its end surface to the adjacent secondary side.

Fit the secondary side to the adjacent side.

1. Place non-magnetic sheets (e.g. resin) of approx. 0.3 mm thickness in the both gap parts between the primary and

secondary side, and move the primary side towards the secondary sides which were installed in Step 1. Remove the

non-magnetic sheets after moving the primary side toward the secondary side. When removing, be careful not to scratch

the primary and secondary sides.

2. Place the secondary side unit on the remaining secondary side area on the stage the same way as the first pair of the

secondary side units that have been installed.

3. Press the side surface of the secondary side to the stage, and fix it with the hexagon socket head cap screw as

temporary joint.

4. After fitting and pressing the secondary-side edge to the secondary side which was installed in Step 1, secure the

temporarily fixed secondary side with the hexagon socket head cap screw.
