Draw a labelled circuit diagram of a simple electric motor and explain its working . In what why are these simple electric motors different from commercial motors ?

Text Solution

Verified by Experts

Commercial motors differ form the motor explained above in the following aspects : (i) an electromagnet replaces permanent magnet, (ii) the coil consists of a large number of turns, and (iii) the coil is would on a soft iron core. The coil and the core are together known as armature and they enhance the rotation speed of the motor .
