Explain the working of electric motor
Asked by Renu.R.Nair | 27 Sep, 2008, 09:49: PM
Expert Answer
Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy.
1.) An electric current in a magnetic field will experience a force
2.) If the current carrying wires is bent into a loop, when the two sides of the loop which are at right angles to the magnetic field will experience forces in opposite direction.
3.) The pair of forces creates a turning influence or torque to rotate the coil.
4.) Particle motors have several loops on an armeture to provide a more uniform torque.
