wound rotor motor mill drives

The wound rotor induction motor has some distinct application advantages historically, it has been used for hardtostart, high inertia fans, or where power system requirements demand a soft start with a liquid rheostat, or a static secondary speed control, the wound rotor is an important alternative drive where limited range adjustable speed is required
