Advantages and disadvantages of traditional motor and disc motor

the traditional motor refers to the conventional permanent magnet motor, which is easy to saturate at the root of the tooth, with serious cogging torque and large positioning torque, making it difficult to start.

disc motor: according to its structure, the motor has good heat dissipation performance (the traditional motor stator wraps the rotor inside, so the heat dissipation performance is not very good. Moreover, the application of disc motor in automobile hub and wind power generation should have unique advantages, but the power density is low.

disc motor

generally, the rotor and stator of a motor are wrapped inside and outside. In order to be thin, the disc motor has a stator on a flat substrate, and the rotor is covered on the stator. Generally, the stator is a coil, and the rotor is a permanent magnet or a disc with a permanent magnet attached. Also known as disc motor.
