Product description

The sensorless standstill monitor UG 9146 is used for sensorless monitoring of electric motors for standstill. It measures the induced voltage of the coasting motor at 2 terminals of the stator winding. If the induced voltage approaches 0, this means motor standstill for the device and the output relay switches on.
