Question

Draw figure and explain the construction of 'Electric motor' with its help.

Answer 1

An electric motor is a rotating device that converts electrical energy to mechanical energy.

Construction: An electric motor, as shown in Fig, consists of a rectangular coil ABCD of insulated copper wire. The coil is placed between the two poles of a magnetic field such that the arm AB and CD are perpendicular to the direction of the magnetic field. The ends of the coil are connected to the two halves P and Q of a split ring. The inner sides of these halves are insulated and attached to an axle. The external conducting edges of P and Q touch two conducting stationary brushes X and Y, respectively, as shown in the Figure.
