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.
