Abstract

PURPOSE: To control the speed of a motor, by limiting the flow rate of electrical current of a chopper depending on the voltage of a commutation capacitor as a reference, detecting the reduction in the flow rate, assuring a commutation capacity and increasing the current of the motor.
CONSTITUTION: A signal in spplied from an accelerator pedal 8 to a trigger circuit 9 to regulate the flow rate of current of the chopper 5 to control the speed of the motor 4. The voltage Vco of the commutation capacitor Co of a chopper circuit 3 is applied to a resistor R5. A transistor TR1 is used as an emitter follower to limit an instruction and apply the limited instruction to the trigger circuir if a maximum signal is applied from the accelerator pedal 8 to the trigger circuit 9. This results in preventing the failure in commutation. When the voltage of a capacitor C1 is low due to the increase in the flow rate of current of the chopper 10, the output voltage of an operational amplifier Ao is low and the maximum voltage of resistors R3, R4 has a level determined by Zener diode ZD1. When the voltage of the capacitor C2 rises due to the decrease in the flow rate, the voltage of the resestors R3, R4 is determined by the that of a constant voltage line 7. If the current of thyristors is constant, the current of the motor can be increased at a small flow rate.
