Motors Motors are devices that convert electrical energy into mechanical energy. A motor is a generator operating in reverse. Instead of generating a current by rotating a loop, a current is supplied to the loop by a battery and the torque acting on the current-carrying loop causes it to rotate.

AC Theory Circuits Generators & Motors. Key Points Electrical machines include both generators and motors Motors can usually function as generators, and vice versa Electrical machines can be divided into AC and DC forms The rotation of a coil in a uniform magnetic field produces a sinusoidal e.m.f., proportional 2to I so it gives the highest torque per current ratio over all other dc motors. It is therefore used in starter motors of cars and elevator motors (p. 563 Chapman, 4e, 2005 McGrow Hill). 4.

Motors Motors are devices that convert electrical energy into mechanical energy. A motor is a generator operating in reverse. Instead of generating a current by rotating a loop, a current is supplied to the loop by a battery and the torque acting on the current-carrying loop causes it to rotate. Generators provide nearly all of the power for electric power grids. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators …
