Abstract
PURPOSE: To switch the speed of a motor depending on the frequency of power source through a simple circuit, by providing a frequency switching coil in the same slot at the same phase as the main winding, connecting an auxiliary winding in parallel with the main winding and coupling speed control taps to the auxiliary or main windings.
CONSTITUTION: The frequency switching coil 13 is provided in the same slot at the same phase as the main winding 12 to eliminate the changes in the rotational frequency of the motor due to those in the power supply frequency. The auxiliary winding 14 is connected in parallel with the main winding 12 through a capacitor 15. The strong/weak speed control taps 16, 17 are connected to the auxiliary winding 14 or the main winding 12. The winding configuration of the motor can be easily changed by the switch 8 when there is a change in the supply frequency (50Hz/ 60Hz), and the switch 18 can be used for selecting between the strong/weak speed control terminals.
