Motor Overvoltage Protection KMOP80

Motion

Motor Overvoltage Protection KMOP80

The motor overvoltage protection device with integrated safety is connected between drive controller and motor spindle (synchronous motor).If the mains voltage fails at maximum speed, the synchronous motor feeds back into the DC link. The motor overvoltage protection device detects an excessive DC link voltage, shorts the motor supply lines and brakes the motor. The motor overvoltage protection device can be used as safety component according to Machinery Directive 2006/42/EC.
