<p>PURPOSE:To minimize the number of cables for remotely controlling a motor by combining plural pairs of switching means in a specific relation and thus conducting the control, stoppage and regenerative braking of the rotating direction of the motor externally by a logic signal. CONSTITUTION:The logic signal of forward or reverse rotation command of a DC motor 10 is converted from ''L'' to ''H'' from a terminal T2 and the logic signal of stop command is similarly converted from a terminal T1. The forward and reverse rotations are conducted by operating a transistor 20 or 36 and switching the base drive of the transistors 26, 28, and the stoppage and braking are conducted by conducting the transistor 50 and conducting the transistors 44, 46 through transistors 49, 48. Accordingly, since the motor is operated by the external logic signal, a computer can be readily employed, and the device can be integrated inexpensively.</p> |
