摘要:
A welding set and a welding method that suppresses the unnecessary magnetization of a permanent magnet member by a welding current when welding one metal member including a permanent magnet member and the other metal member together are obtained. The welding set is provided with a work retaining part 3 that retains a work 14; a pressure device 4 located over the work retaining part 3 with a work-providing space interposed; a first welding electrode 8 mounted on a moving part 4a of the pressure device 4; a second welding electrode 10; and a welding transformer 11 that supplies a welding current to both of the welding electrodes 8, 10. Both of the welding electrodes 8, 10 are located on one end side of the work 14 with respect to one metal member and the other metal member respectively, as well as are located so that there is no permanent magnet member 18 between respective abutment terminal of one metal member and the other metal member.

Stator terminals are fastened between head portions and coupling seats in a state of surface contact by screwing relay members onto external screw thread portions of output terminal bolts. Three-phase wire terminals are fastened in a state of surface contact to end surfaces of the relay members at opposite ends from the coupling seats by screwing nuts onto the external screw thread portions of the output terminal bolts. In addition, insulating tubes are interposed between the relay members and extraction apertures so as to cover outer sides of the relay members.

A cylindrical magnetic pole portion of a rotor core is constituted by first and second cylindrical magnetic pole sub-portions prepared as solid bodies. First and second magnetic poles are formed on the first and second cylindrical magnetic pole portions so as to be arranged in a circumferential direction so as to be separated from each other on an inner peripheral side by first and second recessed grooves recessed into an inner peripheral surface, and linked to each other on an outer peripheral side by first and second thin layer portions constituted by floor portions of the first and second recessed grooves.

First and second permanent magnets are each disposed between circumferentially-adjacent pairs of first and second claw-shaped magnetic pole portions so as to contact a circumferential side surface of the first and second claw-shaped magnetic pole portions. An axial length (L1) of a stator core relative to an axial distance (L2) between facing end surfaces of first and second yoke portions is constructed so as to satisfy an expression L1>L2.

摘要:
An output terminal board of this invention is capable of improving easy and simple installation of an electric rotating machine and wiring output harnesses so as to avoid thermal influence from a stator. The electric rotating machine 2 for vehicle acting as a moter or a generator includes brackets 7 and 15 on both front side (pulley side) and rear side of a stator. Further, the electric rotating machine 2 includes a stator three-phase output line output portion and is provided with an output terminal board 8 at one bracket 7, the output terminal board 8 having a terminal for connecting the three-phase output harnesses 6 connected to an external controller. This output terminal board 8 is disposed in such a manner as being capable of joining to the bracket 7 side on which the output terminal board 8 is mounted, and the three output harnesses 6 are taken out substantially in parallel to one another.

An automotive staffer generator apparatus that is inexpensive and compact, enabling engine starting functions and generating functions to be made compatible by improving maximum torque without having to increase the number of turns in an armature winding. An automotive starter generator machine includes: an armature core onto which an armature winding is wound; and a rotor having: a claw-pole rotor core disposed on an inner peripheral side of the armature core; and a field winding installed on an inner peripheral side of claw-shaped magnetic poles of the claw-pole rotor core, and has a starting function for starting an engine and a generating function. Permanent magnets are disposed between adjacent claw-shaped magnetic poles.

[Problem] In a conventional rotating electrical machine to perform starting and power generation, an inverter and a rotating electrical machine body are constructed to be separate bodies, and a three-phase harness is provided between the rotating electrical machine and the inverter, and by a voltage drop or loss in this portion, there have been limitations in the improvement of starting and power generation output, and efficiency at the time of same operating current (determined by thermal limitation of the inverter). [Means for Resolution] Since an inverter unit 22 is integrally attached to a rear bracket 44 and is integrally mounted on the end face of a rotating electrical machine 20 in an axial direction, harnesses to be connected can be made short, and reduction in weight of the harness and improvement in resistance to outer disturbance noise can be realized. Besides, as a rotor 40, since a claw-pole type rotor is constructed in which permanent magnets 40c and 40d are added, inverter base current is reduced, so that the size of the inverter unit 22 can be miniaturized, and it can be integrally mounted to the starting and power generation electrical machine.
