Abstract

PURPOSE: To econimically control coil current by inserting a capacitor while brake coil current is being held.
CONSTITUTION: When brake coil current Ic is applied and the brake is sucked, then a motor M starts, motor current Im decreases. Accordingly, the inter-terminal voltage of a resistor R1 is lower than the Zener voltage of a constant diode ZD1 and a thyristor Thy2 does not operate. Since only the thyristor Thy1 is igited, a capacitor c is inserted in a brake coil BC in series. When the copactor C is inserted like this, brake coil current decreases until a fixed level and the loss generated in the brake coil BC is reduced.
