Induction motor structure

The stator of an induction motor consists of three parts: the stator core, stator winding, and frame. The stator core is a part of the main magnetic circuit. In order to reduce the eddy currents and hysteresis losses generated by the excitation current and rotating magnetic field in the iron core, the iron core is stacked with 0.5mm thick silicon steel sheets. For motors with larger capacity, both sides of the silicon steel sheet are coated with insulation paint as interlayer insulation. The small stator core is stacked and compressed into a whole with silicon steel sheets, and then fixed in the frame; Medium and large stator cores are assembled by fan-shaped punching pieces. There are many slots with the same shape uniformly punched in the inner circle of the stator core to embed the stator winding. Small induction motors typically use a semi closed slot and a single layer (loose down) winding made of high-strength enameled wire, with slot insulation between the coil and the iron core. A semi closed slot can reduce the magnetic resistance of the main magnetic circuit and reduce the excitation current, but embedding wires is less convenient. Medium induction motors typically use half open slots. Large high-voltage induction motors all use open slots for easy wire insertion. In order to achieve good electromagnetic performance, both medium and large induction motors use double-layer short pitch windings.

The rotor is composed of a rotor core, rotor winding, and shaft. The rotor core is also a part of the main magnetic circuit, usually composed of 0.5mm thick silicon steel sheets stacked together, and the core is fixed on the shaft or rotor bracket. The outer surface of the entire rotor is cylindrical. The rotor winding is divided into two types: cage type and winding type.

Cage rotor
A cage winding is a self closing winding composed of guide bars inserted into each rotor slot and ring end rings at both ends. If the iron core is removed, the entire winding is shaped like a "circular cage", hence it is called a cage winding. To save copper and improve productivity, small cage motors generally use cast aluminum rotors; For medium and large motors, due to the difficulty in ensuring the quality of cast aluminum, a structure of inserting copper bars into the rotor slot and welding end rings at both ends is adopted. The cage type induction motor has a simple structure and convenient manufacturing, making it an economical and durable motor. So it has a wide range of applications.

Wound rotor
A three-phase winding composed of insulated wires embedded in the slot of a wound rotor, with the three outgoing terminals of the winding connected.
It is connected to three Slip ring on the rotating shaft, and then led out through the brush. This rotor is characterized by that external resistance can be connected in the rotor winding to improve the starting and speed regulating performance of the motor.

Compared with cage rotor, wound rotor has a slightly complex structure and is slightly more expensive, so it is only used in situations where low starting current, high starting torque, or dispatch is required.
