摘要： A control device for motor generator is provided in which different field current limit values are set in a low rotation speed zone and a high rotation speed zone in power generation, thereby enabling improvement in the degree of freedom in design, and in which continuous operation can be safely carried out since Ifg in power generation at high temperature is made smaller than Ifm in electric driving. In the control device for motor generator in which an engine is started and power generation is performed while a vehicle is running, a field current limit value Ifm in electric driving to start the engine is larger than a field current limit value Ifg in power generation. In the power generation, an inverter mode in a low rotation speed zone for boosting and an alternator mode in a high rotation speed zone for rectifying and outputting a generated voltage without boosting are provided. A field current limit value Ifgi in the inverter-mode power generation and a field current limit value Ifga in the alternator-mode power generation are set differently from each other, and the larger value is set as the value Ifg.

摘要： An output voltage controller for an AC vehicle generator is proposed. The output voltage controller can easily suppress variation in rectified output voltage due to a switching surge without using a slope generation circuit in a voltage adjustment circuit. An excitation circuit that excites a field coil 13 includes a circulation element 31, a semiconductor switch element 33, an inductor 35, and transient voltage absorption means 40. The circulation element 31 is connected in parallel to the field coil 13. The semiconductor switch element 33 is connected in series with the field coil 13 and turned on and off by a voltage adjustment circuit 60. The inductor 35 is connected in series with the field coil 13 and the semiconductor switch element 33. The transient voltage absorption means 40 absorbs a transient voltage generated in the inductor 35 in association with the switching of the semiconductor switch element 33 between ON and OFF.

摘要： A rotational angle sensor constituted of a stator provided with a single-phase excitation winding and two-phase output windings and a rotor having a salient pole and a rotary electric machine comprising this sensor. The two-phase output windings are wound around teeth of the stator. Since the number of turns of each two-phase output winding is the number of turns determined by virtually defining m-phase windings (m is an integer of three or more) and converting the number of turns of the m-phase windings into the number of turns of two-phase windings is smaller than that of the m-phase windings. Therefore, the structure is simple, and the manufacturing process is easy.

摘要： The present invention provides an automotive rotary electric machine and a winding assembly manufacturing method that can simplify complicated connecting operations by mounting into a stator core a winding assembly that is produced using a predetermined number of conductor wires so as to enable windings that are electrically equivalent to zigzag connections to be configured using single conductor wires. In the present invention, a stator winding is constituted by a winding assembly that is mounted into a stator core. The winding assembly is produced by winding wires that are constituted by 2N continuous wires, and includes: slot-housed portions that are housed inside each of the slots of the stator core so as to form pairs that line up in an inner layer and an outer layer relative to a slot depth direction; first return portions at a first axial end of the stator core that link end portions of the slot-housed portions that are housed in the inner layer inside each of the slots and end portions of the slot-housed portions that are housed in the outer layer inside the slots that are (N - M) slots away; and second return portions at a second axial end of the stator core that link end portions of the slot-housed portions that are housed in the outer layer inside each of the slots and end portions of the slot-housed portions that are housed in the inner layer inside the slots that are (N + M) slots away, two ends of the (N-M) wires project at the first axial end of the stator core, and two ends of the (N + M) wires project at the second axial end of the stator core.
