Many friends on the Internet ask: what is the role of the motor stator and rotor? In fact, it’s not that complicated, figure out the structure and working principle of the two, you can know them very well!

Stator Rotor Coil

A common motor consists of two parts: a fixed part called the stator and a rotating part called the rotor. There are also end caps, fans, bases, junction boxes, etc.

The stator is used to generate the magnetic field and mechanically support the motor. The motor stator consists of the stator iron core, stator windings and the chassis. The stator is embedded in the core of the stator and generates an induced electric potential when the current passes through to achieve electrical energy conversion. The main function of the base is to fix and support the stator core. When the motor is running, the heat generated by internal losses is transferred to the base through the iron core, and then radiated from the surface of the base to the surrounding air. In order to increase the heat dissipation area, the outer surface of the motor base is generally designed as a heat sink.

The rotor of the motor consists of the rotor core, rotor winding and rotor shaft. The rotor core is also a part of the motor’s magnetic circuit. The role of the rotor is to generate electromagnetic torque by inducing an electric potential through the current. The rotor shaft is the main component that supports the weight of the rotor, transmits torque, and outputs mechanical power.

The stator and rotor interact with each other, both are indispensable and are important parts for the operation of the motor, so how are they assembled?

There are mainly the following methods.

1. Manual assembly, relatively slow, including rotor insertion magnet, dispensing, stator winding are used manually, inefficient.

2. Manual plus stand-alone assembly, important processes can be produced using equipment, relatively simple manual assembly, compared to pure manual assembly, the efficiency is still a substantial increase, suitable for small manufacturers.

3. Automatic motor assembly line, fully intelligent mode, a whole line, solve all the assembly problems, stator and rotor assembly at once, with automatic screening function, assembly consistent performance.
