Abstract

PURPOSE:To make it possible to control motor gap magnetic flux and execute ideal current control and constant output control, by giving a given reference exciting current from outside by an exciting current regulator. CONSTITUTION:An operation circuit 3 transmits a current command from a speed control current amplifier 3a in accordance with a deviation between a command value of a speed setting circuit 1 and a detected value of a speed detecting generator 2. A multiplication calculater 5 and a division calculator 5' convert this current command value to a value which is corresponding to a reference exciting current command value and proportional to a slip frequency. A 2-phase sine wave generator 7 puts out a sine wave output voltage of 90 deg. phase difference. Multiplication calculators 8, 8', 9 and 9' multiply this sine wave output voltage over the current command and an output of an exciting current regulator 1'. OUtputs of the multiplication calculators 8, 8', 9 and 9', after having been added by addition circuits 10a and 11a, are given to an exciting winding through power amplifiers 12 and 13.
