9-3 Electromagnetic brake characteristics
CAUTION
The characteristics of the electromagnetic brake provided for the servo motor with electromagnetic
brake are indicated below:
Though the brake lining may rattle during low-speed operation, it poses no functional problem.
Though the brake lining may rattle during operation, it poses no functional problem.A leakage
magnetic flux will occur at the shaft end of the servo motor equipped with electromagnetic brake.
