Abstract
PURPOSE:To operate a controller for a motor safely and facilitate the maintenance of the same, by a method wherein the lowering of a voltage after intercepting an AC input power source is detected by a Zener diode while a transistor is driven by the detected value. CONSTITUTION:An inverter control circuit is constituted of a power source transistor T1, a diode bridge DB1, a voltage stabilizing circuit AVR, a speed control circuit 1 for a motor M, a logic power source PV and the like. The speed control as well as the starting and stopping operations of the motor M are effected through transistors(Tr) Q2-Q7, diodes D7-D12 and the speed control circuit 1 while a regenerative power is absorbed by a regenerative power absorbing resistor R4. Upon intercepting an AC input power source, the transistor Q10 is put ON through resistors R15, R16 while the transistor Q1 is put ON through the transistor Q11 and the like. According to these operations, the electric charge of a power source smoothing capacitor C1 is conducted through the regenerative power absorbing resistor R4 whereby a smoothing voltage VDC may be reduced quickly.
