Here are some of the most desirable motor winding materials today: Motor Winding Material #1: Copper. Copper is the most common material used for motor winding construction. This is primarily due to its high electrical conductivity ( 5.96 x 10 7 S/m) and relatively low cost. Designers typically use copper with a very thin enamel coating since ...
Field magnets produce a magnetic field that passes through the winding. These may be permanent magnets or electromagnets. The field magnet is generally on the stator and the winding on the rotor, but in other motor types these are reversed. Electric Motor Bearings. Bearings support the rotor and allow the rotor to spin on its axis.
Copper wire is used in the stator coils. The size of the wire is a function of the motor's expected full-load current, insulation type, and rated operating temperature.

It is because of the low cost, simple and rugged construction of the motor. Moreover, it has good operating characteristics with an efficiency as high as 90%. An induction motor does not have any commutator, like the one we saw in a DC motor. Hence it provides a good speed regulation without any sparking.
