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.
