摘要： A sensor capable of confirming the stop of revolution of a motor inclusive of rotation due to inertia. Signal input lines (A, B, C) are connected to three power feed lines (u, v, w) of an A.C. three-phase motor. A high frequency signal current is supplied to one of the power feed lines, and the difference between current values flowing through the other two power feed lines is extracted from the signal input lines connected to these two power feed lines and is used as the output for a sensor portion (3). Threshold value computation processing of this sensor output is executed by a signal processing circuit (7) and the result of this threshold value calculation output is output as a judgement output (P1) for judging the motor revolution or non-revolution from an ON/delay circuit (8).
