PURPOSE: To drive a motor so as to obtain a strong motor torque simultaneously with preventing backlash, in the case of driving the composite motor which is provided with a plurality of DC motors connected to one another to drive a driven object by simultaneously rotating these DC motors. CONSTITUTION: This drive circuit is constituted so that the motor can be set to be first drive condition with different voltage applied to each DC motor 20, 30 and to the second drive condition with almost equal voltage applied to each of these DC motors in accordance with use conditions of a composite motor 1. |
