An electric car motor uses a current to create a magnetic field at the fixed part of the machine, called the stator, whose displacement sets in motion of a rotating part (called the “rotor”).

Understanding how an electric motor work is pretty simple. Here’s a simplified explanation of how a car's four-pole three-phase AC induction motor works. It starts with the battery in the car that is connected to the motor. Electrical energy is supplied to the stator by the car’s battery. The coils within the stator (made from the conducting wire) are arranged on opposite sides of the stator core and act as magnets. 

Therefore, when the electrical energy from the car battery is supplied to the motor, the coils create rotating magnetic fields that pull the conducting rods on the outside of the rotor behind it. The spinning rotor creates the mechanical energy needed to turn the car gears, which, in turn, rotates the tires.
