The motor speed control for controlling the speed
of an electric induction motor is by modulating the
amplitude and frequency of the driving voltage. When load
increases the speed control controls the speed of the
machine so as to be relatively constant with respect to
frequency of the driving voltage. Obviously,the speed
control controls the amplitude of driving voltage in
proportion to the square of the frequency.
