Abstract

PURPOSE: To provide a control device of a motor by a triac switch, for which a resistor and an induction coil are not used and a field winding is not put in specific connection. CONSTITUTION: Stator windings 11 and 12 and a rotor winding of a motor 10 form a series circuit, which is connected to an AC voltage through two triac switches 15 and 16 connected in parallel. A control device is common to the two triac switches and the triac switch 16 on one side is controlled, so that it conducts only during the positive half period when the AC voltage is positive, while the triac switch 15 on the other side is controlled, so that it be put in continuity only during the negative half period thereof. The control device supplies a trigger pulse to control electrodes of the triac switches 15 and 16 through diodes 27 and 28 in an antiparallel connection.
