    Are you looking for the power train schematics? Control? Sensing?

    Good places to look would be application notes from semiconductor manufacturers. Search National, ON Semi, Fairchild and TI for motor drive, full bridge, pwm converter etc. chips. The app notes will usually have a relevant circuit design. Even if it's not exactly the power range or frequency you're looking for, it will include a lot of the functionality and components you will need.
