Traction motor for electric vehicle： induction motor, permanent magnet motor, who is the future direction?
In the era of fuel cars, we often hear the battle between natural inspirations and turbocharged engines. And in the era of electric cars, there is also a clear debate between electric motors. After the test of the market, there are two kinds of mainstream electric motors on the market at present, one is induction motor (also known as asynchronous ac motor), the other is permanent magnet motor. Induction motor is a kind of motor which has the rotor rotation powered by magnetic torque created by the physical interaction of stator winding magentic field and the induction current generated rotor magnetic field. Tesla Model S and Model X are representatives of induction motor applications. The permanent magnet motor mainly refers to the permanent magnet synchronous motor, and the biggest difference with the induction motor in structure is that the rotor is permanent magnet structure, rather than wound by the electric coil. Which is better, the induction motor or the permanent mag
