... designed to control a brush-less DC motor. However, by
constructing a feedback loop that can detect the outputs of an induction motor, we
can use this motor controller to control an induction ... responsible for the induction
motor s many advantages are clearly explained. Wildi also presents the two types of
induction motors: “the squirrel cage induction motor and the “wound motor . An
explanation ... a control strategy that varies the frequency and voltage of the
signal applied to the windings of the induction motor, while controlling the flux created
in the air-gap of the induction motor. ...
