with a motor control chip or circuitry, changing the voltage changes the speed changing the wattage changes the spinning power.
you can use a resister set or analog resister for speed control only they change speed and power so theres a reduction in power.

Variable frequency drives help to control the speed of the motors. It helps a lot to save energy as well as regulate speed. When you install variable frequency drive in any motor, it helps to increase the speed of the motor as well as ensure efficient workings of the motor.
