for Selection, Installation and Use of Electric Motors and Generators.

 The National Electrical Code
 Local codes and practices

Limited Warranty

1. Baldor Electric motors are warranted for a period of one (1) year, from date of shipment from the factory or factory
warehouse against defects in material and workmanship. To allow for stocking and/or fabrication period and to
provide one year of actual service, the warranty period is extended for an additional period of six (6) months for a
total of eighteen (18) months from the original date of shipment from the factory or factory warehouse stock. In no
case will the warranty period be extended for a longer period. Baldor extends this limited warranty to each buyer
of the electric motor for the purpose of resale and to the original purchaser for use.

2. Baldor will, at its option repair or replace a motor which fails due to defects in material or workmanship during the
warranty period if:

a. the purchaser presents the defective motor at or ships it prepaid to, the Baldor plant in Fort Smith, Arkansas

or one of the Baldor Authorized Service Centers and

b. the purchaser gives written notification concerning the motor and the claimed defect including the date

purchased, the task performed by the Baldor motor and the problem encountered.

3. Baldor will not pay the cost of removal of any electric motor from any equipment, the cost of delivery to Fort Smith,
Arkansas or a Baldor Authorized Service Center, or the cost of any incidental or consequential damages resulting
from the claimed defects. (Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above exclusion may not apply to you.) Any implied warranty given by laws shall be limited to
the duration of the warranty period hereunder. (Some states do not allow limitations on how long an implied
warranty lasts, so the above limitation may not apply to you.)

4. Baldor Authorized Service Centers, when convinced to their satisfaction that a Baldor motor developed defects in
material or workmanship within the warranty period, are authorized to proceed with the required repairs to fulfill
Baldor’s warranty when the cost of such repairs to be paid by Baldor does not exceed Baldor’s warranty repair
allowance. Baldor will not pay overtime premium repair charges without prior written authorization.

5. The cost of warranty repairs made by centers other than Baldor Authorized Service Centers WILL NOT
unless first authorized in writing by Baldor.

6. Claims by a purchaser that a motor is defective even when a failure results within one hour after being placed into
service are not always justified. Therefore, Baldor Authorized Service Centers must determine from the condition
of the motor as delivered to the center whether or not the motor is defective. If in the opinion of a Baldor
Authorized Service Center, a motor did not fail as a result of defects in material or workmanship, the center is to
proceed with repairs only if the purchaser agrees to pay for such repairs. If the decision is in dispute, the
purchaser should still pay for the repairs and submit the paid invoice and the Authorized Service Center’s signed
service report to Baldor for further consideration.

7. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

1-2 General Information MN1800

Receiving Each Baldor motor is thoroughly tested at the factory and carefully packaged for

shipment. When you receive your motor, there are several things you should do
immediately.

1. Observe the condition of the shipping container and report any damage
immediately to the commercial carrier that delivered your motor.

2. Verify that the part number of the motor you received is the same as the part
number listed on your purchase order.

Storage If the parts are not put into service immediately, store them in a clean, dry and warm

location. If the storage location is damp or humid, the exposed metal surface of the
motors and windings must be protected from moisture. If the ambient temperature
decreases suddenly, condensation may form. Protect all parts from moisture.

Unpacking Each Baldor motor is packaged for ease of handling and to prevent entry of

contaminants.

1. To avoid condensation inside the motor, do not unpack until the motor has
reached room temperature. (Room temperature is the temperature of the room
in which it will be installed). The packing provides insulation from temperature
changes during transportation.

2. When the motor has reached room temperature, remove all protective wrapping
material from the motor.

3. The magnet track sections may come packaged in one or more boxes. Do not
flip any magnet track sections inside the box. Unpack the magnet track
sections one piece at a time. Place each section on a clean non–magnetic
surface away from other magnet track sections and any other ferrous material.

4. Always keep the magnet track sections at a safe distance from each other. If
the assemblies are to be left unattended for any period of time, precautions
should be taken to prevent accidents due to the strength of the magnets (it is
best to leave them in their packing material to prevent injury due to magnetic
attraction). Persons who will come in contact with this assembly while
receiving, transporting, storing, installing, disassembling or at any other time,
must be made aware of this danger.

Handling Be extremely careful. Keep in mind:

1. The magnetic attraction between the motor and the magnet assembly is
extremely high. Keep fingers and other body parts away from these objects to
avoid injury by this magnetic attraction.

2. Use proper care and procedures that are safe during handling, lifting, installing,
operating and maintaining operations.
Improper methods may cause muscle strain or other harm.

Section 2
Installation & Operation

Overview Installation should conform to the National Electrical Code as well as local codes and

practices. When other devices are coupled to the motor, be sure to install protective
devices to prevent accidents. Machinery that is accessible to personnel should provide
protection in the form of guard rails, screening, warning signs etc.

Location The motor should be installed in an area that is protected from direct sunlight, corrosives,

harmful gases or liquids, dust, metallic particles, welding spatters and vibration.
Exposure to these can reduce the operating life and degrade performance. Be sure to
allow clearance for ventilation and access for cleaning, repair, service and inspections.
Ventilation is extremely important. Be sure the area for ventilation is not obstructed.
Obstructions limit the free passage of air. Motors get warm and the heat must be
dissipated to prevent damage.

These motors are not designed for atmospheric conditions that require explosion proof
operation. They must NOT
or dust.

Clean Room Stages prepared for Class 10, 100 and 10,000 clean room requirements can be ordered

as an option to our standard products. Materials must be suitable for the specified
environment. The customer must perform the final cleaning due to contamination during
shipping and handling.

The most common changes to the stages include the replacement of the bellows,
installation of special greases, elimination of bearing shields and the removal of other
non–critical components that may contribute to particle generation.

Mounting a Stage to the Machine Base and Payload To Stage

S Your stage is provided with mounting holes to attach the stage to a machine base. If

your stage is supplied with bellows, you must remove the bellows to access the
mounting holes. The mounting holes are typically non–threaded, counter–bored
holes that accommodate a variety of screw sizes. It is recommended that a
hardened machine screw be used. Refer to the mechanical drawings provided with
your stage for mounting screw size and hole locations.

S The flatness of your mounting surface will greatly influence the flatness and

straightness specification of your stage. The stage structure will tend to mirror the
flatness of the mounting surface. For the stage to maintain its specification, it must
be mounted to a surface that is flat (maximum error of 0.0005 inches per foot). A
maximum of 0.010 inches per foot is the maximum mounting surface flatness error
allowable for operation of the stage. However, at 0.010 inches per foot mounting
base flatness, the stage flatness and straightness specification will be degraded.

S The mounting surface must be clean and free of particles that could affect flatness

(particles that come between the stage and the mounting surface) . It is also
recommended that the base of the stage be cleaned to remove contamination.
Cleaning with alcohol or acetone is suggested, however avoid submersion or
contamination of the internal components.

S When mounting the payload to the slide assembly, use the same precautions

mentioned for the stage. Refer to the stage outline drawing for hole locations and
specifications.

S When pinning is required, Baldor recommends that the stage be machined and

assembled at the factory.

Note: It is strongly recommended that a thread locking compound be used when

mounting the stage to the base and when mounting the payload to the slide
assembly.

LMAC Linear Induction Motor

General Description: Single or three phase, linear AC induction motor primary.
Construction: Epoxy encapsulated and steel laminated coil assembly (motor primary) Motor secondary

(customer supplied) must conform to the following specifications: 1/8–inch aluminum or
copper plate backed by a
be at least the with of the motor coil assembly.

Maintenance: Motor should be kept dry and relatively free of contamination. This motor is water

resistant, not water proof. Avoid submersion. Avoid contact with petroleum–based
solvents. Alcohol or soapy water can be used to remove contaminants.

Motor specifications: Refer to catalog or outline drawing supplied with motor for mechanical dimensions and

electrical specifications.

Motor Mounting: Your motor may be supplied with either base or foot mounting, refer to catalog or outline

drawing supplied with motor for mounting details and hole dimensions. It is
recommended that all available coil assembly mounting holes be utilized to properly
secure the coil assembly. If the coil is in motion, the motor wires must be strain relieved.
We recommend that the motor secondary be secured with 1/4inch fasteners on the left
and right sides of the secondary, every four to six inches of its length. An air–gap of 1/8
inch is recommended. Refer to linear induction motor duty cycle–force–current curves in
this booklet for information regarding the affects of air–cap size on motor performance.

Electrical Connections For voltage and current specifications, refer to Catalog BR1800 or to documentation

enclosed for custom motors. The 10 foot flying leads can be cut to remove excess length
if required. Connectors are available; contact a Baldor representative for more
information.

For single phase motors, refer to the table supplied with this booklet for capacitor
selection.

Mounting The motor primary must be aligned (parallel) to the equipment guide ways within 0.005″

(0.127mm) on each end. Use gauge blocks and shims as necessary. Precise parallel
alignment of the motor to the equipment guideways is required. Align the stationary half
of the motor to the guideways. Then align the moving half with the stationary half.

When securing the primary to the equipment base do not allow the screws to penetrate
the motor more than .25″ deep (to prevent damage to the motor windings).

To mount the motor secondary, slide the table over the secondary and align the mounting
holes. The secondary is to be secured to the moving table with screws after the proper
amount of shims are added to maintain an air gap of .015″ min. to .020″ max. (unless
otherwise specified) between the secondary and the primary. This is achieved by
ensuring that the plastic shim provided does not bind anywhere over the length of the
primary when moving the table top with secondary back and forth by hand.

The plastic shim between the primary and the secondary can now be removed. Be sure
that the secondary is centered and runs parallel to the commutator to within .005″ at each
end.

Electrical Check: With an ohmmeter across input terminals, verify that the resistance reading does not drop

to zero when the secondary / commutator assembly is moved over the entire length of the
stationary primary. If a zero reading is observed, inspect the connections between the
commutator brushes and the power input wires. In addition, inspect the connections
between the motor windings and the commutator bar.

Motor Removal: Insert the plastic shim between the primary and secondary to maintain the air gap. First,

disconnect the power input wires. Next, remove the screws between the secondary and
the moving table as this allows the secondary to sit on the primary. Then remove the
mounting screws between the primary and the base. Finally, the complete motor
assembly can be removed and placed on a level, flat surface.

Secondary Removal: If just the secondary must be removed,slide the table with the secondary attached, to one

end of the primary. Insert a .015″ minimum plastic shim between the secondary and the
primary to maintain the air gap. Remove the screws between the secondary and the
sliding table. Move the table out of the way and slide the secondary out using extreme
caution so as to not damage the brushes. If brushes are worn out, contact Northern
Magnetics for replacement.

Secondary Reinstallation: Place .015″ minimum plastic shim on primary face. Next place .015″ min fiberglass shims

on the brush assembly and completely depress the brushes into their holders. With the
brushes toward the commutator bars, slide the secondary onto the primary face (with the
shim in place). When the secondary is in place, gently remove the shim from between
the brushes and commutator bars.

Note: Ensure that the shim between commutator and brushes has rounded ends

and that they do not cut the leads to the commutator bars.

Refer to “Mounting” instructions to reinstall.

For either method, it is extremely important to uniformly tighten the mounting screws.
Improper tightening will bend the primary or secondary and damage the motor.

If there is not enough space to install the coil assembly as described, use this alternate
procedure.

Alternate Installation Refer to Figure 2-1.

1. Place the non–magnetic shim on the magnet track.

2. With a firm grip on the coil assembly, place one end of it on the shim and slide it

3. Align the fastening screw holes on the slide with the holes on the coil assembly.

4. Loosely install all the mounting screws.

5. Insert enough shims between the slide and the coil assembly to fill the gap.

6. Tighten all the mounting screws, alternating in a systematic manner while

7. Remove the shim that sets the air gap prior to operation.

tightening such that the coil assembly is drawn–up evenly leaving a uniform air
gap between the coil assembly and the magnets. This air gap must be
maintained along the entire length of the magnet assembly i.e.; the coil
assembly must never touch the magnets at any point when moving along the
length of the magnet assembly and the air gap specification must be
maintained at all times.

Multiple Coil Assembly Operation

In addition to maintaining an air gap, multiple coil assemblies must also maintain a
spacing factor of 1.8″. In other words, the space between coil assemblies may vary,
however, the distance from the front end of the first coil assembly to the front end of the
next must be a multiple of 1.8″. See Figure 2-2.

Ensure that this spacing is established at the time of installation.

Operation Considerations The motor must always be operated within the specified operating parameter limits.

Exceeding those limits will permanently damage the motor Refer to the motor
specifications for operating parameter limits.

The motor must never touch the magnets during operation. Refer to “Adjust Air Gap”.
Remove the shim that sets the air gap between the motor and the magnets prior to

operation.

Note: Be aware that the total bearing load includes the magnetic attractive force.

The following steps must be completed to ensure safe and proper operation.

1. Verify that all electrical wiring and cables are properly connected. Refer to the
manual provided with the control for this information.

2. Adjust the control continuous current limit to match the motor’s continuous
current specifications.

3. Adjust the servo drive current to match the motor’s current specification.

4. Refer to the motor specifications for operating parameters. Adjust the control
parameters as necessary to the motor data specifications.

5. Adjust the control for the proper P.I.D. loop tuning. Begin at a low gain setting
and increase the gain as necessary.

6. Strain relieve the wires prior to operating.

Modular Magnet Track
Installation Refer to Figure 2-3. Some magnets are provided in modular segments. This is the

recommended procedure to install these modular magnet track sections.

Note: It is recommended that rubber coated tool handles be used to reduce injury

(pinching fingers etc.) and protect the surface of the magnets.

1. Bolt the coil assembly onto the underside of the slide (carriage). Ensure the
leads extend in the proper direction.

2. Install the magnet track on the base–plate adjacent to or between the linear
bearing. Magnet track ends should not oppose each other.

Place a 0.030″ ± 0.005″ thick non magnetic shim on the magnet track. The
shim thickness must be equal to the recommended air gap (space between the
coil assembly and the magnet track).

3. Hold the slide with a firm grip and move it over the magnet track section/shim.

Note: The slide will be drawn forcefully towards the magnet track and may

overshoot the rails if not held firmly.

Check the space between the shim and the coil assembly. If the space
between the shim and the coil assembly is large, uniformly loosen the mounting
screws allowing the coil assembly to be fully and evenly lowered onto the shim.
Insert another shim thick enough to fill the gap between the coil assembly and
the slide, see Figure 2-4. Tighten the mounting screws once again.

1. Install the coil and magnet assemblies. While mounting the coil, be sure to
adjust coil assembly so it is centered within the magnet assembly with equal air
gap in the vertical and horizontal positions. See Figure 2-6.

2. Verify that the coil assembly is centered within the magnet assembly with equal
air gap in the vertical and horizontal positions along its entire length of travel.
The coil assembly must never be allowed to touch the magnets at any point
from one end of travel to the other.

Note: For modular magnet mounting, magnets are mounted end–to–end without

spacing. The mounting hole pattern is repeating and is unaffected by magnet
segments. Hole pattern repeats across joining ends of magnets.

Multiple Coil Assembly Operation

In addition to maintaining an air gap, multiple coil assemblies must also maintain a
spacing factor of 2.4″. In other words, the space between coil assemblies may vary,
however, the distance from the front end of the first coil assembly to the front end of the
next must be a multiple of 2.4″. See Figure 2-6.

Ensure that this factor is established at the time of installation.
