The problem with that is then his servo amps won't work. They need some sort
of
velocity feedback for the control loops, and position info for the motor
commutation. That is generally done with either a resolver or encoder,
but it needs one. Unless it can accept either, you can't just pull the
resolver out.

He can't use these on AC or brushless motors.
