Abstract
PURPOSE: To prevent the false operation of a starting relay due to the change of line voltage, by inversely winding the first winding connected to a main winding in the starting relay and the second winding, to which terminal voltage or auxiliary winding voltage is applied, mutually.
CONSTITUTION: A starting relay 5 is formed by the first winding 7 connected in series to a main winding 2 of a single-phase induction motor 1, the second winding 8 connected in parallel with the main winding 2 and the first winding 7, a relay contact 9 connected in series to an auxiliary winding 3 and a starting condenser 4 and a plunger 10, which is operated by means of the winding 7, 8 and opens and closes the relay contact 9. The winding directions of the first winding 7 and the second winding 8 are mutually reversed. Thus, width between main winding current in case of the normal operation only of the main winding 2 and main winding currents in case of starting by the main winding 2 and the auxiliary winding 3 can sufficiently be formed, and the false operation of the starting relay 5 due to the change of the voltage of a power source terminal 6 can be prevented.
