switched reluctance drive

Hello, I have a friend that has a appliance store that gave me a motor and a driver card that they are using in the new Maytag washers. The driver board is labled "switched reluctance drive". It has six 13A 120V fet's driving a 3Ph motor rated at 3A per Ph. Also the duty cycle seems lower than desired. I haven't determined the pulse method to drive the board. The motor also has a timed encoder on the end which they use as a tach. These motors are labled variable speed, reversable. Would these make a good spindle drive?
Also, with these drivers producing variable freq, would these have potential as a "VFD"? I realise the circuit would have to be amplified, and I suspect the output as square wave, which induction motors don't like. It seems these motors and drives are plentyful.
