PURPOSE:To improve the accuracy and the reliability irrespective of temperature conditions by using a rotor angle position signal division signal generator and a torque signal generator. CONSTITUTION:An oscillator 3 for generating a carrier, a rotor angle position detector 2 for generating a rotor angle position signal modulated by the carrier, a rotor angle position signal division signal generator 12 which receives the carrier and a torque command signal E(X) and generates a rotor angle position signal division signal Z, an inversion Z, torque signal generators 13, 14 for generating torque signals, 2-phase/3-phase converter 8 for converting the torque signal from 2-phase to 3-phase to generate a 3-phase AC signal proportional in amplitude to the torque command signal and proportional in frequency to the rotating speed of the rotor, and a 3-phase AC generator 9 for controlling the conduction angle are provided. |
