Abstract
PURPOSE:To eliminate the influences of the jitters and drift of a delay circuit by handling phase data equivalent to a delay time after phase ajustment without delaying pulses, whose phases are to be adjusted, directly. CONSTITUTION:Dectection pulses from a rotation detector 22 are applied to the latch pulse input terminal of the 1st latch circuit through an amplifier 23. To the latch pulse input terminals of the 2nd and 3rd latch circuits, a reference signal ref and the output pulse of a monostable multivibrator 28 (operating with, for example, the zero output of a cyclic counter 27 mentioned hereafter) are applied. Those three latch circuits latch the output of the cyclic counter 27 with latch pulses and send latch outputs to a microprocessor 30. The microprocessor 30 performs arithmetic (reference signal numeral-detection pulse numeral+fixed phase phase-difference numeral) and with the output, the rotary phase of a motor 21 is controlled through a DA converter 31 and a driving amplifier 32.
