Abstract
PURPOSE:To simplify a control system and heighten its reliability, by controlling a primary current ineffective component and a primary current effective component independently of each other. CONSTITUTION:The difference between a magnetism-resisting current command and a signal proportional to an ineffective current supplied from an ineffective current detection circuit is determined by a calculator 3. A signal corresponding to the difference is amplified by an amplifier 4. The amplified signal is applied to a comparator 6 which determines the output voltage of a pulse width modulation inverter 12. An effective current command and a primary current effective component are compared with each other by a calculator 23. A signal corresponding to the difference between the command and the component is amplified by a current deviation amplifier 24 so that the signal becomes a substantial slip frequency command. This command is added to the output signal of a speed detector 15 by an adder 25. The sum is applied to an oscillator 26.
