- Option: Supplied with mating connector.
EZ Connection Method (OCS)
Winding Protection
PTC thermistors are installed in STOBER synchronous servo motors as a configuration feature to implement thermal winding protection. This makes it possible for the motor to exceed the maximum permitted winding temperature with the appropriate devices turned off.
