Working Of Electric Motor

Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor : A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. ... Whereas the force on the side CD of the coil is in the upward direction.

Working
Most electric motors operate on the principle of electromagnetic induction, but there are motors that use other electromechanical processes, such as electrostatic force and the piezoelectric effect. The fundamental principle of electromagnetic motors is based on the mechanical force that acting on the conductor through which electric current passes and it is located in the magnetic field. The direction of the mechanical force is perpendicular to the conductor and the magnetic field.



Electric motors have found widespread application in various industrial processes, systems and devices.

Electric motors have found widespread application in various industrial processes, systems and devices. These are some of the application fields:

In industrial processes – motors with highly standardized characteristics and dimensionsBlowers and special pumpsHousehold appliances and devicesMachine and power toolsElectric watches – with small motorsHybrid vehicles (such as Tesla motor)Ship propulsion – motors with high capacity and powerPipeline compressionPumped-storage applications

All electric motors are powered by two sources. They are mainly powered by direct current (DC) sources (batteries, rectifiers or motor vehicles), but some are powered by alternating current (AC) sources (power grid, generators or inverters).

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.
