A Fan Motor Shaft is a mechanical section for rotating and converting torque. The size of the shaft significantly affects the torque in these devices. The structure of the fan motor, Fan motors are very simple in construction. They consist of a synchronous or asynchronous electric motor, with a fan wheel of the associated shaft, and the connections for the lines. The Fan Motor Shaft is placed on ball bearings that are fixed inside the stator. The impeller is attached to the rotor casing. Such design provides air cooling of the motor which allows using the fans in the wide temperature range.
