How does an electric motor works?

An electric motor is a device used to convert electricity into mechanical energy opposite to electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field Motors have many different working parts in order for them to continually rotate, providing Power as needed. Motors can run off of direct current (DC) or alternating current (AC), and both have their benefits and drawbacks.

Working of an electric motor

  1. Stator: The stationary part of the motor, specifically the magnet. Electromagnets are often used in order to provide more power.
  2. Rotor: The coil that is mounted on an axle and spins at high speeds, providing rotational mechanical energy to the system.
  3. Commutator: This component is key in DC motors, Without it, the rotor would not be able to spin continuously due to opposing forces created by the changing current. The commutator allows the rotor to spin by reversing the current each time the coil does a half turn.
  4. Power source: Supplies an electromotive force which causes current to flow in the system.
  5. Brushes: These are connected to the terminals of the power source, allowing electric power to flow into the commutator.
