Construction and Working of Electric Motor

Construction and Working of Electric Motor Points : Construction and Working of Electric Motor, Definition Definition It is a device, which converts electrical energy into mechanical energy. Construction It consists of a suspended rectangular coil between the poles of a permanent magnet. The ends of the coil are attached to a split copper ring, which rotates along the coil. This split ring made to have a continues contact with the two stationary pieces of carbon called brushes, which are connected to a battery. The current enters through one brush and leaves through the other. Working When electric current pass through the coil a mechanical force act on the coil and electrical energy is converted into mechanical energy.
