Abstract
PURPOSE: To change the speed in non-stage and in a wide range by providing a transistor controlled by a series circuit of a variable resistance with a capacitor to the output of full wave rectifying circuit connected with the power supply through the main winding or auxiliary winding.
CONSTITUTION: The auxiliary winding 13 and the full wave rectifying circuit 14 are connected with each end of the main winding 12 of the single phase induction motor respectively, and the variable resistance 16 and the capacitor 17 are connected with the output of the full wave rectifying circuit 14 in series to control the conduction of NPN transistor 18 inserted in parallel. Thus, the transistor 18 is controlled by the voltage across the capacitor 17, a decrease in variable resistance 16 to make the time constant less increases the number of times of "on-off" to make the current IB of auxiliary winding 13 greater and the equivalent rsistance of transistor 18 is reduced to control the phase lag of IB, a non-stage speed change can be done in a wide range.
