2. LINEAR SERVO MOTOR
2.4 Instructions for discarding the linear servo motor
Demagnetize the secondary side (magnet) of the linear servo motor by heating over 300
, then discard it in
accordance with Law for Promotion of Effective Utilization of Resources.
WARNING
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the operators but also the people around the work place must use
abundance of caution when the linear servo motor is disassembled or discarded.
For example, one who uses a medical device like a pacemaker must keep away
from the machine.
The permanent magnet on the secondary side makes the magnetic bodies
(primary side [coil] and secondary side [magnet]) generate suction.
Use special caution with the handling of the secondary side which is
demagnetized before/after disassembly.
When the linear servo motor is disassembled or discarded, do not put magnetic
bodies (including the primary side [coil], the other secondary sides [magnet] and
tools) close to the secondary side (magnet). The secondary side (magnetic) can
have as double suction power as mounted normally, which may cause a serious
injury. In all cases, pay full attention to the ambience of workplace to avoid this.
Magnetic body such as iron
Secondary side (magnet)
Magnetic suction power: Max. 5 ton
A suction power is generated when magnetic bodies (including tools) are put near
the permanent magnet on the secondary side. Be sure to use nonmagnetic tools
for the disassembly and disposal of the linear servo motor or the work around it.
These are required for the improvement of workability and safety ensuring.
WARNING
The personnel who work for the disassembly or disposal of the linear servo motor
or those who are around the workplace must not work wearing electronic devices
(watch, calculator, personal computer, etc.) and magnetic recording media (IC
card, magnetic card, floppy disc, etc.) and must not bring them around the
secondary side (magnet). Magnetic influence may cause the operation failure or
malfunction.
When the linear servo motor is disassembled or discarded, use cautions in order
to avoid accidents so as not to get your hand stuck.
Do not touch the secondary side after the demagnetization of the secondary side
(magnet) by heating over 300
until it becomes cool enough. Otherwise, you
may get burnt.
