This paper describes the recent technology and the trends of motors for home applications. The features such as high-efficiency, low-noise, small size and low-cost are demanded for the motors of home applications. The permanent magnet synchronous motor (PMSM) has come to be used as a motor to satisfy such demands in Japan. This paper mainly describes the technology of PMSM design for the compressor drive application such as an air conditioner. The effects of rotor configurations including the arrangement of permanent magnets on the efficiency performance are examined and the stator configurations such as the distributed winding and the concentrated winding are also discussed. The effects of the ratio of magnet torque and reluctance torque on both efficiency and cost are also discussed. Several motors used for the actual electric home appliances such as air conditioner, refrigerator and washer are introduced.
