Abstract

PURPOSE:To rotate a periodic motor at the predetermined torque by obtaining a speed feedback signal from a phase modulation signal outputted from a resolver, an inductosyn, etc. CONSTITUTION:A numerical control device 11 outputs an instruction voltage Vref corresponding to a rotating speed value responsive to the phase modulation signal Esin(omegat+theta) outputted from a phase modulation signal generator 21, and a speed signal converter 15 outputs a speed signal K2.E.dtheta/dt relative to theta from the phase modulation signal Esin(omegat+theta). A multiplier 14 multiplies the error signal ERR of the instruction voltage and the second signal by the phase modulation signal Esin (omegat+theta). After synchronization rectifier 16, 18 synchronize and rectify the output of the multiplier 14 by the rectangular waves S1, S2 of difference phase of 90 deg. applied from an oscillator 23, and the rectifier 16, 18 will supply the rectified waves to the sin coil and the cos coil of a synchronous motor 20.
