イツチ手段により切り替えが検知されたときには
、チヨツパーを短時間、短周期で駆動してその間
の平均電流が大きくなるよう制御する制御手段を
設けたことを特徴とする２モータドライブ回路。 In a two-motor drive circuit having a chopper serving as a variable voltage power supply for two DC motors connected in parallel, and a switch means for switching the direction of current supplied to each DC motor between forward rotation and reverse rotation, The switch means switches the current flowing through the armature of each DC motor, and when switching is detected by another switch means that detects switching of the switch means, the switcher is driven for a short period of time and in short cycles. A two-motor drive circuit characterized by comprising a control means for controlling the average current of the motor to increase.
