What is a motor and what does it do?

What is a motor?

Motor (Motor) is an electrical appliance that converts electrical energy into mechanical energy. It consists of a coil wound around a metal core placed between magnetic poles. When an electric current is passed to the coil between the magnetic poles, the coil will turn around the axis. And when the polarity is switched, the rotation of the coil will reverse its original direction.

What does the motor do?

The motor acts to drive various workpieces to move. The motors are found in applications ranging from electric clocks to large electric motors. Used for ship towing and compression of oil pipelines and oil storage pumps up to 100 megawatts.

How many types of motors are there?

Motors can be divided into 2 types according to the nature of the electric current.

DC electric motor

It is a motor that requires direct current. through the coil to cause the suction and repulsion of the permanent magnet and the electromagnet generated by the motor coil so it can rotate

AC electric motor

It is a motor that is used with an alternating current system. When receiving electrical energy, it creates a magnetic field. And will cause the induction of the current in the rotor winding, known as the rotor. which is the part that serves to provide mechanical energy As a result, AC electric motors are called induction motors.
