Abstract

PURPOSE: To improve the efficiency of a motor, by using either one of two windings under partial load operation.
CONSTITUTION: A motor 2 for driving a compressor 1 has two windings. Both windings are energized to provide a specific output at the time of high load operation, while the circuit is changed over to activate only either one of them at the time of partial load operation. This can reduce the output of the motor 2 and keep the motor efficiency very high at the low load operation. This means the compressor 1 is efficiently operated with reduced power consumption.
