Electromagnetic induction is the key to why a motor like this spins—and that's why it's called an induction motor.Photo: An efficient AC induction motor. Photo by Al Puente courtesy of NREL.How does an AC induction motor work? Here's a typical, everyday AC induction motor with its ...
How does an EC motor work? The EC (electronically commutated) motor is asynchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a ...
How Does an AC Induction Motor Work? In simple terms, the AC induction motor works by electrifying conducting copper coils positioned around the stator. The alternating current flowing through the copper coils induces a rotating magnetic field. Obviously, in an EV, the electricity that allows this...

How does an electric motor on an EV function? Before learning how the electric motor functions, you need to know a few basics of electricity. First, electric current/ electricity moving through a conductor generates a magnetic field around it. Moreover, when a current-carrying conductor is in...
There are many other types of electric motors, such as AC induction motors, AC synchronous motors, stepper motors (really a specialized form of brushless motor), and so on. All of these motors operate on variations of the principles we’ve looked at. They differ only in how they perform ...
A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stat...
