Abstract: In a stator structure 1 of an outer rotor generator, a pressing portion 33 provided on a first portion 31 of a connecting terminal 30 is configured to protrude inward in the radial direction of an annular coupler 20 when the connecting terminal 30 is attached to the coupler 20. The coupler 20 is formed with a circular cylindrical guide protrusion 23, and an outlet of a stator winding 5 having wound on a salient pole 10b is configured to be guided by the guide protrusion 23, bent inward in the radial direction and reach the pressing portion 33. After fusing processing, the first portion 31 on which the pressing portion 33 is provided is bent at a right angle toward a side opposed to a side with which the stator winding 5 is connected, and then a distal end thereof is locked at a lock portion 26.

Abstract: In an insulator to be inserted into each slot to be attached to adjacent teeth formed at a rotor or a stator of an electric rotating machine, the insulator is composed of insulator segments that are made divisible in a longitudinal direction parallel to a rotational axis of the rotor at a position corresponding to 2 slots and are made divisible in a lateral direction perpendicular to the rotational axis of the rotor, the insulator segments have surfaces to be coupled to each other of a same shape in the lateral direction, and the insulator segments have a creepage distance that is made longer than a distance in the lateral direction, thereby enabling to elongate the creepage distance and to improve work efficiency.

Abstract: A multipolar magnetogenerator, which is operable under sufficient performance of its capability, permitting simultaneous extraction of various voltage outputs and is excellent in spatial efficiency, includes a magnet rotor (3) as an outer rotor and a multipolar stator (10) opposed to the radially inner surface of the magnet rotor (3) to permit extraction of an output of generated power from output windings (30) wound around the stator core 10. A transformer core (21) has a primary winding (31) and secondary windings (32, 33) wound therearound and is located adjacent the radially inner circumferential surface of the stator (10), which is remote from the magnet rotor (3), and the output windings (30) are connected to the primary wiring (32) such that transformed outputs are extracted from the secondary windings (32, 33).

Abstract: An engine generator comprises a fan cover made of die-cast aluminum alloy, and a power control unit including an aluminum base sheet. The base sheet has a power control circuit formed thereon. The fan cover includes a mounting portion to be attached to the power control unit. When the power control unit is attached to the fan cover, a surface of the aluminum base sheet comes into intimate contact with an outer surface of the mounting portion. Heat generated at the unit is transmitted to the fan cover, and then released from the fan cover serving as a heat releasing member.

Abstract: A connecting terminal for a stator which is fitted and fixed in a fitting bore provided in a bobbin included in the stator, includes an external-conductor connecting terminal section fitted and fixed in the fitting bore with one end connected to an external conductor protruding from the fitting bore, a flat plate-shaped connecting plate section connected at one end at right angles to the other end of the external-conductor connecting terminal section and extending outwards in a radial direction of the stator, and a coil connecting terminal section which extends away from the bobbin and which is connected at right angles to the other end of the connecting plate section, so that the coil connecting terminal section can be folded to a position superposed onto the connecting plate section.
