Abstract:
1. A control apparatus for an electrical rotating machine, comprising: a stator to arrange coils, the coils generating a rotating field by permitting a driving current to flow into the coils; two rotors disposed in the electrical rotating machine on the same axis of rotation and being driven by the rotating field and associated with the stator; an inverter to supply driving currents to the coils, the inverter compounding the driving currents to drive the two rotors independently of each other by a compound current which is a sum of the driving currents for the respective rotors; and a controlling section that controls the driving currents to drive each of the rotors on the basis of desired speeds respectively, the controlling section controlling a phase difference between the respective driving currents for driving the respective rotors to suppress a maximum amplitude value of the compound current to a small value.
