Motors and Inverters for Home Appliances

摘要

The motor and inverter play an important role inimproving the product functions of washing machines andrefrigerators, such as noise reduction and power consumption.We have developed high-performance motors and low-priced,high-performance inverters by applying advanced numericalanalysis to their design. For direct-drive (DD) washingmachines, noise reduction was achieved by using a DD motorhaving lower torque ripple and an inverter controlled by anadvanced motor-driving software. For refrigerators, powersaving was achieved by using an inverter to drive thecompressor motor and tan motors together with a controlmethodology making best use of the product's features.
