1 Production Outline
1-1 Structure of liner servo motor
Our linear servo motor consists mainly of the primary side (LM-FP) with cores and coils, and the secondary
side (LM-FS) with yoke and permanent magnets.
As the secondary side has permanent magnets, take special care in handling.
Motor coil
Fig. 1 Structure of linear servo motor
1-2 Primary side
The primary side has motor cores to which windings are applied. The cores are protected by mold.
Compared with metal parts, the mold is susceptible to breaking or cracking due to shock or stress, which
may deteriorate the product's quality.
Therefore, pay special attention in carrying and installing not to damage the mold.

Yoke side
(Almost no attraction force generated)
Magnetic force
1-3 Secondary side
The secondary side has a yoke with permanent magnets on. The mold is applied to the surface of it.
As it has permanent magnets, magnetic attraction force is generated between it and magnetic material as
iron.
The magnetic attraction force is generated mainly on the magnet side. (Almo st no attraction force is
generated on the yoke side.)
Therefore, take safety measure in handlin g to avoid accidents due to the attraction force.
In addition, the magnetic force is released into the air, so do not make devices that are affected by the
magnetic force such as pacemaker, watch, etc… approach to the product.
<Permanent magnet>
Permanent magnet releases the magnetic force into the air all the time.
So the magnetic attraction force is generated if magnetic material is placed close to the magnet.
In addition, as the magnetic force is released into the air, devices susceptible to the magnetic force may be
damaged if they are placed near the product.
As our linear servo motor has high quality magnets, take special care in handling.
The size of the magnetic attraction force is about 4 [kgf/

Especially if two secondary sides are placed close to each other,it is highly dangerous as the magn etic
attraction force will be greatly strong. For the secondary side, take the sufficient safety measure.
If more than one secondary side are used together, or when you exchange secondary sides, never
leave the secondary sides unattended.

install it to the device.
It is very dangerous to leave the secondary side (magnetic plate) unattended after taking it out from
the package. Furthermore, it is highly dangerous to leave the secondary sides (magnetic plates)
unattended together, therefore never do so.
Install with the following procedure to eliminate clearances between the secondary sides (magnetic plates).
1. Use nonmagnetic tools (Explosion-proof beryllium copper alloy safety tool: Nihon Gaishi, etc) when
installing the secondary side (magnetic plate).
2. If a secondary side (magnetic plate) is already installed and another secondary side (magnetic
plate) is to be added, place the additional secondary side (magnetic plate) away from the side
already installed, then horizontally slide the additional side to the specific position.
3. To install two or more secondary sides (magnetic plates) side by side, the accumulated location
tolerance of installation screw pitch must be within -/+0.2mm. Clearances may be resulted on the
secondary side (magnetic plate) depending on how to install.
Precautions of how to Handle Linear Motors
WARNING
<Confirmation after installation>
1. Before operating the product (regardless of the power distribution), confirm that no operator is
within the range of motion. In case that multiple operators are engaged in the operation, confirm
the safety with one another to prevent any dangers.
2. Before you move the product (regardless of the power distribution), confirm that there are no tools
or bolts within the range of motion.
3. Pay attention so that a person with a medical device such as pacemaker won't approach the
product. The device may be affected by the permanent magnets.
4. Do not place magnetic material such as iron close to the product.
5. Before handling, remove metal items such as watch, piercing jewelry, necklace, etc…
6. Immediately stop using the product if any abnormality is found about the product.
7. In using the product as a vertical axis, take me asures to prevent the axis from dropping, as the
motor doesn't have the holding power when it is not energized.
8. Before conducting a test operation, etc. as a confirmation process, move the slider manually
(without power distribution) to check if the actual operation is possible without any problems.
<Inspection process>
What is described below are the main items and steps for inspection after installing the product to a machine
or equipment.
The items to be inspected may vary according to the type of a machine or equipment; therefore you are
required to select the appropriate items to be inspected in such cases.
Conduct this inspection process without energizing (disconnect with a drive unit).
Step (1)
Visual inspection
Step (2)
Screw inspection
Step (3)
Connection inspection
Step (4)
Dimension inspection
→ Check if the product contains foreign objects and if it has any cracks, etc.
→ Check if the fixing screws are tightened enough.
Check if the power/signal lines are connected to the correct terminal blocks or
→
connectors.
Check if the primary and secondary sides are rubbing within the full range of
→
motion, if the installation dimension is the same as specified and if any stresses
are applied to a linear guide or cables.
(Note 1) In addition, check if there are any installation errors of a linear guide.
(Note 2) Before executing JOG operation and setup with the combination of a linear scale and drive unit,
complete the inspection process above.
(Note 3) Refer to “MDS-D Series Linear Servo System Installation manual” for JOG operation and setup
with the combination of a linear scale and drive unit.
