ABSTRACT:
A rotary body control apparatus for controlling both speed and phase of the rotary body such as d.c. motor in a single circuit. Speed control is accomplished on the basis of a reference signal without provision of independent control system and, a phase comparison unit serving as means for detecting speed is provided to control phase. A number of stabilized regions is provided so as to effect locking-in with the reference signal in a suitable stabilized region with a reduction in time. The apparatus consists of speed signal generating means, reference signal introducing means, output signal forming means, output signal sampling means, and oscillating means.
