Abstract:
An electric motor-generator and an engine are linked using a first belt that is looped around a crank pulley that is mounted to a crank shaft and a one-way clutch pulley that is mounted to a rotating shaft. An electronic control unit drives the electric motor-generator as an electric motor and drives the compressor by the electric motor-generator if engine speed is less than or equal to a predetermined value.

Abstract:
An engine, an electric motor-generator, an oil pump, an air conditioner, and a first power transmitting means that performs power transmission among a crank shaft of the engine, a rotating shaft of the electric motor-generator, and rotating shafts of the oil pump and the air conditioner are included. The first power transmitting means has: a crank pulley; a first electric motor-generator pulley; an oil pump pulley; an air conditioner pulley; a first belt that is wound around these pulleys; and a first one-way clutch that is interposed between the rotating shaft and the first electric motor-generator pulley so as to transmit a rotational driving force from the crank shaft to the rotating shaft without transmitting a rotational driving force from the rotating shaft to the crank shaft, and the electric motor-generator is motor driven while the engine is being driven.

Abstract:
A method of controlling an electric rotating machine for a vehicle includes an electric rotating machine (1) including a rotator having a field winding (5) and a stator having an armature winding (3), a field current controller (9) for controlling a field current supplied from a direct-current power supply to the field winding (5), and a power converter (6) for converting a direct-current power into an alternating-current power and applying the power to the armature winding (3). When the field current controller (9) starts to supply a current to the field winding (5) for starting an internal combustion engine, the power converter (6) supplies a power to the armature winding (3) so that magnetic flux in a direction opposite to that generated by the field winding (5) is generated simultaneously with or immediately before starting the power supply.

As a result, the rotating electrical machine for a vehicle can be obtained in which exciting force of harmonic components is reduced, electromagnetic noise, torque ripple and the like are effectively suppressed, and the productivity is excellent.
Abstract:
A material of the stator core is different from a material of the housings, in a state where one end portion in the axis direction of the stator core is contacted to the first housing, and the other end portion in the axis direction of the stator core is contacted to the second housing; and a neighboring portion of a contact portion, at which the first housing is contacted to the stator core, and another neighboring portion of a contact portion, at which the second housing is contacted to the stator core, are connected by a connecting component in the axis direction, of which material is the same as a material of the stator core, whereby the first housing and the second housing are connected each other; and the first housing and the second housing face each other in a state where a gap intervenes between both housings.

A method of manufacturing a rotor for a magnet type rotating electrical machine includes the steps of: cutting and laminating pieces of the core of the rotor, to thereby form a core (3); mounting the core (3) on a rotating jig (10); forming a magnet piece (2p) into a predetermined shape by sintering; mounting a predetermined number of the magnet pieces (2p) on a regulating jig (20); pressing the magnet pieces (2p) by the regulating jig (20) while rotating the core (3) by the rotating jig (10), to thereby mount the magnet pieces (2p) on the core (3); and adjusting an axial position of the magnet piece (2p) so that an axial end surface of the core (3) and an axial end surface of the magnet piece (2p) are aligned with each other.
