There are inverters available from most electrical manufacturers that are designed for the speed control of induction motors.
Have a look at http://www.motor-control.co.nz for some examples.
There are some special motors with a very high resistance rotor that can be reduced in speed by a reduction in the applied voltage. Thes are a high slip motor with a high resistance rorot and sometimes are used as the integral moto on a fan unit. Do not try tovary the speed of a standard induction motor by voltage control as the motor will be damaged.
