ABSTRACT:
The apparatus comprises a motor stator which is stationary relative to the rotating spindle, while the rotor of the motor rotates in synchronism with, for example, the nut of a screw mechanism which as a whole forms part of the spindle. A variable dependent on the angular position of the nut is controlled by corresponding operation of the motor and can be maintained irrespective of the speed of rotation of the spindle. The apparatus is particularly intended and suitable for the work spindles of machine tools.
