Chinese motor fan supplier, high-quality price, large number of fan motors, electric fan motors are single-phase AC motors, it has two windings inside, one is called the running winding (also called the main winding), the other is called the start winding (also called the secondary Winding).
The starting circuit is composed of split phases, so that the main and auxiliary windings are spaced apart by 90° electrical angle. The speed control circuit is composed of a reactor speed control switch in series, and the voltage of the motor is changed to realize speed control by adjusting the size of the reactance.
An electric fan motor generally refers to a motor fan. The motor fan is a motor with a fan hub and blades. There are evenly distributed slots along the outer circumference of the fan hub. The blades are inserted in the slots and are permanently connected by welding, bonding, etc. The blades are integrated with the fan hub.
The overall balance of the motor fan is good, which can save the man-hours required to adjust the balance, the weight is more than 30% less than that of the bolt-connected fan, and the vibration and noise of the motor when using the utility model are reduced.
