Household appliances

Currently, about 50 to 100 special motors are used in ordinary households in industrialized countries. The main types of motors are: permanent magnet DC motors, single-phase induction motors, series motors, stepper motors, brushless DC motors, AC servo motors, etc. In order to meet the increasingly higher requirements of users and adapt to the needs of the development of the information age, and to achieve energy-saving, comfortable, networked and intelligent household appliances, the replacement cycle of household appliances is very fast, and high efficiency is proposed for the supporting motors. , low noise, low vibration, low price, adjustable speed and intelligent requirements. The motors used in the household appliance industry are being updated, and household appliances driven by high-efficiency permanent magnet brushless DC motors represent the development direction of the household appliance industry. For example, the currently popular high-efficiency and energy-saving variable frequency air conditioners and refrigerators use permanent magnet brushless DC motors to drive their compressors and fans. The washing machine uses a low-noise multi-pole flat permanent magnet brushless DC motor, which can eliminate the original mechanical reducer and directly drive the drum to achieve stepless speed regulation. It is a high-end product among current washing machines. The vacuum cleaner uses a permanent magnet brushless DC motor to replace the original single-phase series motor, which has the advantages of small size, high efficiency, low noise, and long life.
