​

What is electric motor?

​Construction of an electric motor

• It has a rectangular coil of wire ABCD.

• It has got a strong horseshoe magnet. The coil ABCD is placed perpendicular to this magnet.

• The ends of the coil ABCD are connected to split rings P and Q. These split rings play the role of the commutator. It helps reverse the direction of the current flow.

• The inners part of the split rings is insulated. It is attached to the axle. The axle is free to rotate.

• The external side of the conducting edges of the split rings is connected with the stationary brushes. These brushes X and Y are connected with the battery. This completes the circuit.
