What type of motors are used in new energy vehicles?

[SanHolden]

Mostly permanent magnet synchronous motors. A permanent magnet synchronous motor is a synchronous motor where the excitation is provided by permanent magnets to generate a synchronous rotating magnetic field. The permanent magnets act as the rotor to produce the rotating magnetic field, and the three-phase stator windings induce three-phase symmetrical currents through armature reaction under the influence of this rotating magnetic field. At this point, the rotor's kinetic energy is converted into electrical energy, and the permanent magnet synchronous motor functions as a generator. More details are as follows: Energy conversion efficiency: Permanent magnet synchronous motors have the advantages of high power density, high energy conversion efficiency (approximately 90%-95%), and relatively low energy consumption. However, the inclusion of permanent magnets increases costs, and there is also a risk of demagnetization under high temperatures and vibration conditions. Brands that use them: Domestically produced electric vehicles mostly use permanent magnet synchronous motors, such as BAIC New Energy, BYD, and XPeng Motors.
