Abstract

PURPOSE:To obtain a secured starting torque at all times along with to enlarge the speed control range by a method wherein a gate of a control commutator element is controlled by a voltage comparator in which the voltage contains a ripple of a approximately same phase with the AC sources is made the comparative voltage. CONSTITUTION:A switch 3 and the series circuit of a stack diode 4 and a SCR5 are connected to the AC voltage 1 through a motor 2. Further, at a low speed driving time the switch 3 is opened, the comparative voltage contained ripple considerably at the DC source 1 and approximately the same phase is given to a comparator 10, a flip flop 8 is reset by the output thereof to OFF a transister for a short circuit 7 and to ON a SCR5. At the same time, a transistor 11 is ON, after the time integrating timer R6, R7 and C3, the speed is controlled while SCR is on an non trigger condition. Accordingly, along with the speed range is enlarged, the starting is made around the zero phase, thus the generation of noise can be controlled.
