how speed control of induction motor?..

Answer / eugene

Speed control control of induction type motors (also known
as squirral cage motors), are mainly achieved by
controlling the input voltage to the motor terminals. This
can be done by altering the frequency of the supply by
using a Variable Speed Controller, or if the speed control
is allowed to be multi-staged, resistive circuits can be
inserted using contactors and resistors, thus limiting the
voltage applied.

how speed control of induction motor?..

Answer / karpagam

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.
