ABSTRACT:
A directly motor-driven spindle assembly in a rotary shaft having one end supported on a bearing and the other end connected to a load a, driving apparatus fixed to the rotary shaft to rotate the rotary shaft, and control apparatus for controlling the movement of the rotary shaft toward the side of the load according to the movement of the rotary shaft from a predetermined position. The control apparatus prevents the jumping motion of the rotary shaft which occurs as the load increases to enable the directly motor-driven spindle assembly to operate at a high rotating speed without the jumping motion.
