REFRIGERANT UNIT WITH VARIABLE PERFORMANCE MOTOR COMPRESSOR
Document Type and Number:
Japanese Patent JPS60187272
Kind Code:

Abstract:
The cooling system has its compressor realised as an electromotor with multiplexed polarity. The first polarity configuration includes two windings - a start winding and a main winding. The second polarity configuration is the main winding alone. The motor runs on a two-pole winding at max. power and on the single-pole winding at reduced power. - Alternatively, a main winding is provided for a high speed two pole type of configuration and a start and main winding for the low speed four pole type of configuration. Yet again each configuration may have two windings - start and main.
