Abstract

PURPOSE:To minimize a phase shift between a rotating field and a rotor, and improve efficiency, by reading a phase adjustment degree according to speed command, out of memory, and by correcting commutation signal according to the phase advancement degree for phase advance. CONSTITUTION:The input of the rotational position theta of a servo-motor 4 to the speed arithmetic means 11 of a servocontroller 1 and a commutation signal producing means 12 is provided. The commutation signal producing means 12 is formed with a ROM, and when the input of the absolute rotational position thetato the means 12 is provided, then sin(theta) according to the input is read out, and the output is generated. In the meantime, by an adder 13, a deviation V between speed command V0 and detection speed V is found. The deviation V is multiplied by the commutation signal sin(theta) with a multiplier 14, and as a result, the input of current controlling signal i0 having the momentary value of a level corresponding to the speed command, to a phase adjustment means 15 is provided.
