Reduction of electrical power consumption in household appliances has become an important and essential technology, in light of heightened public concern regarding energy conservation and environmental protection in recent years, and the institution of a “top-runner” energy-saving standard wherein the industry-leading power consumption level is taken as the baseline.
We have thus sought to develop a new drive control technology that would achieve both reduced power consumption and noise in the motors used in compressors,which are the principal component in air conditioners and account for approximately 95 percent of air conditioner power consumption.
This report explores that the effects of this new drive control technology comparing with previous method and the possibilities of applying it in other interior permanent magnet (IPM) motors through magnetic field analysis through experiments and JMAG
Keywords: IPM motor, position sensor-less, phase difference control, magnetic field analysis.
