Bell-type Annealing and Bluing Furnace for High-efficiency Motor Stator or Rotor

The product adopts electric heating mode and is widely used for stress-relief annealing, oil removal, aging, bluing and other process of high-efficiency motor (refrigerator motor, air conditioner motor and electric vehicle motor) stators or rotors. It not only reduces the internal stress of punching sheets in the machining process but also increases the magnetic flux of motor stators or rotors, so as to reduce the energy consumption of the motor in the working process and achieve high efficiency. The product is characterized with compact structure, convenient loading, uniform temperature, uniform bluing color, obvious iron consumption reduction and other advantages. It is an ideal supporting product for producing high-efficiency motors.
