Abstract: PURPOSE:To simplify the constitution of a rotational angle and speed arithmetic circuit by performing control through the operation of a PLL circuit so that the output of a phase difference computing element is zero and obtaining an angle signal proportional to the rotating speed of a rotor from a counter. CONSTITUTION:A phase difference computing element 1 inputs two-phase signals Asinkthetam and Acoskthetam from a rotational angle and speed detector for the rotator and outputs a phase difference signal V=Asin(kthetam-thetas) according to two-phase signals sinthetas and costhetas from a function generator 7. The signal V is applied to a comparator 5, which compares it with the zero level and outputs a U/D switching signal for an up/down counter 6. Here, when the input signal to the comparator 5 is positive, the output is '1' and the counter 6 counts up, but when negative, on the other hand, the output '0' and the counter counts down. The counter 6 is applied with clock pulses of reference frequency fs. The output thetas of the counter 6 is applied to the generator 7. Thus, the constitution of the arithmetic circuit can be simplified.
