Hint: An electric motor can be defined as an electrical device that converts electrical energy into mechanical energy. Most electric motors operate on the basis of interaction between the motor's magnetic field and electric current in a wire winding, which is the underlying principle, to generate force in the form of torque applied on the shaft of the motor.

Complete step-by-step answer:
The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.
The following are the parts of an electric motor:
DC Power Supply: It is the component in which the operating power source is generated.
Commutator: the direction of the electrical source provided by the power source is aided by this part of an electric motor.
Rotor Armature: It performs continuous rotation while the motor is running. It is also there to aid with the movement and supply of electrical power to other parts of the motor and vehicle.
Axle: The axle of an electrical vehicle contains part of the main power source, which provides one with the ability of direction of the vehicle, through steering and gear usage.
Field Magnet: A field magnet is within an electrical motor and it provides a magnetic field, which enables the inner coil wire within a DC motor to rotate.
The basic idea of an electric motor is really very simple, you put electricity into it at one end and a metal rod rotates at the other end giving you the power to drive any machine.

Note: Electric motors are so important that they impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and many other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy.
