PROBLEM TO BE SOLVED: To provide a controller of rotary electric machine capable of properly reducing electromagnetic force which may cause to generate noises even when the load on the rotary electric machine changes.SOLUTION: The controller of rotary electric machine includes: a harmonic calculation section that calculates a harmonic current to be superimposed on a fundamental wave current which flows on wirings 12U to 12 W to suppress an electromagnetic force which acts on a motor 10; and an operation part that operates an inverter 20 so that a drive current, in which the fundamental wave current flowing on the wirings 12U to 12 W is superimposed with the calculated harmonic current, flows on the wirings 12U to 12 W. The harmonic calculation section calculates the amplitude and the phase of the harmonic current to be superimposed based on the conditions relevant to variation of the load on the motor 10.SELECTED DRAWING: Figure 1 |
