Abstract

PURPOSE:To eliminate a reverse direction detector and a mechanical brake in a motor brake device by switching the energization of a coil to produce a restricting state between a rotor and the coil by inverting the output of one position detecting element in response to the stopping operation of the motor. CONSTITUTION:The rotor of a motor (not shown) is rotatably driven by the output of a differential amplifier 10a. An FF20 is set by closing a normally open stopping switch S3, causing the output to become from L level to H level, thereby switching switches S1, S2 to opposite state to the states shown. Thus, both output terminals of position detecting Hall elements HA, HA' at the intermediate position of motor coils (not shown) to invert the polarity of a signal applied to the input of an amplifier 10a, thereby reversing the polarity of the output signal. Accordingly, a restricted state is produced with the rotor coil, thereby stopping the rotation of the motor.
