ABSTRACT:
A highly dependable motor drive system capable of driving a motor with certainty even in a submersion accident and preventing overcurrent from flowing to the motor on the occasion of switching the direction of rotation. It is so arranged that, of a first and second relay for rotating the motor in the normal and reverse directions, respectively, in response to operation of associated switches, the first relay is selectively actuated and the second relay is de-energized. As the associated switch is operated, the energization of the coil of the second relay is maintained for a while by the function of a bypass circuit so that the actuation of the second relay is stopped only after actuation of the first relay with a transient motor stand-still time therebetween.
