Induction Motor – Brief Review
One of the ‘best’ invention of human beings – Induction Motor (IM) –
simple, robust, heavy-duty applications, low maintenance
Main components – rotor, stator, slip ring (mechanical interface)

Induction Motor – Brief Review
(Based on notes by Prof. F Rahman, UNSW)
, SKEM 3133 : EM&D
Induction Motor – Brief Review
In induction motor – stator currents produce the magnetic field for
excitation and also induces flux in rotor to produce the torque-producing
current
Figure above shows the flux pattern of 4-pole induction motor at three
instant of time with ¼ cycle apart.
Refer to video shown in the e-learning.
