Introduction of the external rotor motor
The external rotor motor is a motor with a rotating shaft and a fixed shaft. The motor solves the problem of shaft seal leakage of the mechanical transmission pump, which is a new type of industrial pump offering full sealing, no leakage and no pollution.
The product is mostly used in fans, such as ceiling fans.

Advantages of the external rotor motor
  • The external rotor motor has the characteristics of space saving, compact and beautiful appearance.
  • The external rotor motor is suitable for installation in the impeller with optimum cooling effects and doesn't need a V-belt, additional tension belt or other equipment.
  • The external rotor motor uses a pair of sealed deep groove ball bearings, so that it has a long service life.
  • High-accuracy ball bearings can minimize vibration and has low noise during operation.
  • Special squirrel cage rotor structure and one-time die-casting process ensure that the motor starts smoothly and has high speed.
  • High-quality electromagnetic materials and special electromagnetic structure to ensure the efficient operation of the motor and save energy.
  • High-sensitivity thermostat assembly is installed at the end of the motor winding to ensure safe and reliable operation of the motor.
