As is well known, an electric machine is an electromagnetic device that performs interconversion between electric energy and mechanical energy using a magnetic field as a medium. In order to establish the air gap field within the machine necessary for energy conversion of the machine, there are two approaches. One is to pass exciting current inside the motor winding to generate magnetic field, and the electrically excited motor needs to be supplied with external energy continuously to maintain current flow; the other is a novel rare earth permanent magnet to generate a magnetic field; because of the inherent characteristics of the permanent magnet, after the permanent magnet is magnetized in advance, a magnetic field required by energy interconversion can be established without external energy; the structure can simplify the motor, saves energy and is widely used in new energy automobiles.
