Radial load: the load applied vertically to the motor shaft
Thrust load: the load applied horizontally to the motor shaft

1.1.9 Cautionary Items on Servomotor Equipped with a Brake

 Brake noise
The brake lining may issue chattering noise during operation of the motor equipped with a brake. As
it is caused by brake structure and is not abnormal, the noise will not effect functional operation.
 Others (shaft end magnetization)
The shaft end of the servomotor equipped with a brake is subject to leaking magnetic flux during
energization of the brake coil (when the brake is released). At the instance, chips, screws and other
magnetic bodies will be attracted. Cautions are required.
 Brake power source
There is no polarity for the brake power source input.
