Attention! Risk of physical damage to watches and magnetic storage media.
Strong magnetic forces may destroy watches and magnetisable data storage media near to the torque motor
system!
Do not bring watches or magnetisable data storage media into the vicinity (< 300 mm) of the torque motor
systems!
Please read all safety instructions before performing motor maintenance.
Warning!
Obstacle removal and maintenance can only be performed by HIWIN technicians or authorized dealers, and
with appropriate protective equipment.
Do not perform any maintenance actions while the motor is running. The controller must stop the motor
first.
Please turn off the power and the main switch of the machine (Please refer to the machine manufacturer's
instructions for operation).
After the power is turned off, there will be residual voltage in the system. Please wait for sufficient
discharge time before disconnecting all power connections.
Turn off the cooling system, release the pressure to discharge the cooling liquid and remove the cooling
connection (Please refer the instructions of the cooling machine).
Disassemble the motors in order.
Clean the metal particles on the motor regularly.
Regularly check the air gap between the stator and rotor of the motor to keep it clean and undamaged.
HIWIN torque motor is a direct drive system, there will be no wear during operation, but even so, improper
operation or incorrect use environment will still shorten the life of the motor or even damage it. It is
recommended to conduct measurement and maintenance every quarter:
1
Confirm the flow rate of the cooling system and remove impurities and particles.
2
Measure and eliminate partial blockage of the cooling system.
3
The detection mechanism or electrical connection must not be loosened.
4
Detect possible wear or aging of the cable.
5
Check the air gap between the stator and rotor to confirm that there is no leakage that may cause foreign
matter, dust or particles to invade.
6
To test the insulation resistance of the three phases of the motor. It must meet the requirements of 1000V
DC
60 sec > 100 M
Ω
at 25
℃
. If the insulation resistance decreases gradually at the same temperature
compared to the previous several measurements, the motor may have begun to age, so special attention
should be paid.
