Failsafe brake operating when supply off (a braking force is applied when de-energized) on LS non IE, IE3 asynchronous three phase IMfinity® motors range.
Advantages
Reliability and robustness.
Performance and safety.
Flexible conception.
Supervision on brake duties : wear indicator microswitch, tightening and loosening indicator microswitch.
Auto-return brake release systems : simple, lock off or remote lever.
Variable speed construction : thermal protection , encoder and/or forced ventilation.
