Answer»
An electric motor is a device which converts electrical energy into mechanical energy. Electric MOTORS and their functions: A power supply – In general, a simple motor has a DC power source. It PROVIDES power for the armature of the motor or field coils. ... Armature Coil – Supporting the engine to run. An AC generation is an electric generation that converts mechanical energy into electrical energy in form of alternative emf or alternating current it WORKS as the principals of Electromagnetic Inductor working of an generator: Whne the armature rotate between the poles of the magnet an axis perpendicular to the magnetic field the FLUX which links with the armature changes continuously Due to this on emf is induced in the armature This produces on electric current through galvanometer & the slip rings & brushes. The galvanometer rings between the POSITIVE & negative values This indicates that there's is an alternating current flowing through the galvanometer. |
