Not sure that would work, brake rotor temperatures can easily exceed the Curie temperature of the magnet, and I imagine the reduced induction of the coils could fry something somewhere.

In case it wasn't clear, I was talking about bolting a motor to the spindle that applies torque directly to the rim.
