[Problem] To provide a motor control device and a motor control method by which it is possible to perform, with high responsiveness, correction of offset and amplitude unbalance of a drive current of a motor in square wave control . [Solution] This motor control device and motor control method perform smoothing processing of d axis and q axis feedback currents Id, Iq during square wave control and generate estimated d axis and q axis current commands Id*, Iq*, and also subtract the d axis and q axis feedback currents Id, Iq, and generate d axis and q axis correction currents ∆Id, ∆Iq as variable components.

Abstract

A generator having: a stator fixed to a housing having a first bracket having a bearing section that pivotally supports one end section of a rotating shaft and a second bracket covering a cooling fan that rotates together with the rotating shaft; and a rotor surrounded by the stator and fixed to the rotating shaft. The stator (25) is fixed to the first bracket (22) and a tube-shaped section (22b) is integrally provided therein, said tube-shaped section (22b) surrounding the stator (25) so as to cause cooling air sucked in by a cooling fan (29) to flow between the outer circumference of the stator (25) and same, and the second bracket (23) is joined to the tube-shaped section (22b). As a result, cost can be reduced because a long through-bolt is not required when joining the first and second brackets and stator cooling efficiency can be improved as a result of the configuration whereby cooling air flows along the outer circumference of the stator.

Abstract

Each of two inverter units has a control circuit (microcomputer). The intensity of a target waveform signal corresponding to a voltage to be outputted from each of the inverter units is successively determined by considering the effective power and the ineffective power outputted from each of the inverter units. By performing communication between the control circuits, the phases of the two inverter units are matched with each other so as to prevent output shortage of an engine or an AC generator by an abrupt load increase.
