explain the construction and working of an electic motor
Answers
Constructions
The main components of a typical electric motor are:
Rotor – The moving part of the motor. It turns the shaft to transfer the mechanical power.
Stator – The stationary part, which has windings or permanent magnets.
Air gap – It is the space between stator and rotor.
Windings – Wires that are wrapped around the iron magnetic core.
Commutator – The mechanism that switches the input of DC and certain AC machines.
A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. A force acts on the coil which rotates it continuously. When electric current is passed into the rectangular coil, this current produces a magnetic field around the coil.
ELECTRIC MOTOR
An electric motor is an electrical machine that converts electrical energy into mechanical energy is known as electric motor.
CONSTRUCTION AND WORKING FOR ELECTRIC MOTOR
- The electric motor construction can be done using the rotor, bearings,stator ,air gap,windings,commutator etc.
- The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power.
- The electric motor works on the principle of magnetic effects of currents.
- Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it,the coil rotates as a results of the forces acting on the coil.
