How does one control the speed of a wound rotor indution motor and how does this speed change affect the torque of the motor?
The motor in question is a 220HP.

Actually, what you are really controlling is a WRIM is the torque, which indirectly determines the speed based on the load. Changing the resistance in the rotor changes the torque-speed curve that you are working with. This gives a more detailed description.
