Typically, automotive alternators are used to convert a vehicle’s mechanical energy into electrical energy that can be used to power the electrical devices in the automobile. An electric motor is a machine that converts electrical energy to mechanical energy. There are two main groups of electrical motors: DC and AC motors. They make our lives easier, so it is important that they run as efficiently as possible. A 3 phase AC motor is the absolute standard for car companies when they make an electric vehicle.
