  • Electric blanket and hot wall systems
  • Washer motor, soybean milk machine motor
  • Fan motor, air conditioner motor
  • Fractional motor, direct current motor, AC brushless motor
  • Water pump, transformer, rectifier
  • Lighting systems, rechargeable batteries
  • Various electric heating appliances
