A control apparatus and a control method of an on-vehicle dynamo-electric machine 1 are provided for efficiently controlling functions as a starter-motor and as a charging generator. In case that the dynamo-electric machine 1 acts as a charging generator, when a rotation speed of the dynamo-electric machine 1 is not higher than a predetermined value, a power is generated by applying a compensation current from and inverter to an armature coil 3 for phase control. On the other hand, when a rotation speed of the dynamo-electric machine 1 is not lower than a predetermined value, operation of the inverter is stopped. Thus, controlling a current applied to a field coil 4 by a field coil current control means 5 generates a predetermined target voltage.

A coil conductor for a dynamoelectric machine which is a coil conductor to be inserted into slots of an iron core of a dynamoelectric machine, the coil conductor being made of a plurality of wire elements compression-bonded to each other by press-forming so as to have a substantially rectangular cross-section. The wire elements may be twisted by at least 360 degrees and the twisted wire elements may be further twisted. The coil conductor includes straight sections and crossover sections, providing an overall shape of a crank wound in a serpentine manner and the straight sections have different intervals that are different in accordance with the different periodical numbers n th and (n+1) th. The coil conductor for a dynamoelectric machine may further include an electrical insulating material disposed around the conductor of a square cross-sectional shape that is formed by simultaneously pressing the conductor bundle with an electrical insulating material placed therearound before press-forming.

A control device for a vehicle AC generator which restricts an upper limit of a field current to the maximum field current at a set voltage even when a power generation voltage becomes large, is obtained. In the control device for the vehicle AC generator, in which a DC voltage obtained by rectifying an AC output voltage of an armature coil in the AC generator with a rectifier is applied to a field coil to obtain a field current and the field current is controlled by ON/OFF of a switching element connected in series to the field coil, an upper limit restriction unit in which an upper limit of on-duty of the switching element is set to a set voltage/the DC voltage, is included.
