Abstract:
A method an apparatus for providing speed control in a spindle system are provided. The apparatus includes an air turbine spindle that rotates at a speed, an electromagnetic device coupled to the spindle for creating a torque to maintain a desired speed of the spindle, and a tachometer for generating a measurement of the rotational speed of the spindle. The electromagnetic device applies a torque to the spindle in response to the measurement to change the speed of the spindle to the desired speed.
