摘要： PROBLEM TO BE SOLVED: To enhance the space factor of a stator coil in a slot of a stator and to facilitate winding of the stator coil in the slot.
SOLUTION: The core comprises an annular outer core, and an inner core where a plurality of slots for winding the stator coil periodically open to the outer circumferential side, and the slot is formed to have the substantially same width from the inner circumferential side to the end of outer circumferential opening so that the stator coil is arranged in line. Consequently, the space factor of the stator coil in the slot can be enhanced. Furthermore, since the outer circumferential opening of each slot can be spaced apart in the circumferential direction, the stator coil can be prevented from being inserted into an adjacent slot accidentally in winding and the stator coil can be wound easily in the slot.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular dynamo-electric machine system whose power-generating characteristics in a high speed are improved. SOLUTION: A stator winding comprises two independent three-phase windings 3a, 3b. An inverter 101 is connected to the three-phase windings 3a, 3b.

摘要： PROBLEM TO BE SOLVED: To provide an alternator in which a stator winding can be easily wound to improve an occupied area in a stator iron core, and winding resistance is reduced due to no coil end in structure. SOLUTION: In the stator iron core, stator pawl magnetic poles alternately extend from both sides of an axial direction on positions opposing a rotor to form a plurality of magnetic poles. To easily mold such a complicated shape, the stator iron core comprises an iron dust core molded by compressing iron powder having an insulation-processed surface. In this way, since the stator winding can be wound circularly in the stator iron core to facilitate winding, an occupied rate in the stator iron core can be improved. Further, since the there is no coil end in structure, a winding resistance value can be reduced. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To apply a stator coil to a core without causing any damage while enhancing the space factor of the stator coil in a slot, and to facilitate the formation of a magnetic path between the stator coil and a rotor. SOLUTION: The core is constituted of an annular outer core and an inner core having a plurality of slots in the outer circumference, and a stator coil is placed in the slot of the inner core in wave winding and turned up at the start-of-winding slot so that the number of turns in the slot becomes constant. Consequently, the stator coil can be attached easily with no interference even if overlap portions exist at both ends of the stator coil. Since the stator coil can apply a load to both end sides of each slot in the circumferential direction, the joint of the inner core and the outer core is prevented from being released even if a magnetic path is formed between the stator coil and the rotor.

摘要翻译：要解决的问题：为了将定子线圈施加到铁心上而不会造成任何损坏，同时增加了定子线圈在槽中的空间因数，并且有助于在定子线圈和转子之间形成磁路。解决方案：芯部由环形外芯和内芯构成，内芯在外周具有多个槽，定子线圈放置在内芯的槽中，并在起始时向上卷起使得槽中的匝数变得恒定。因此，即使定子线圈的两端存在重叠部分，也能够容易地安装定子线圈。由于定子线圈可以在周向上的每个槽的两端侧施加负载，所以即使在定子线圈和转子之间形成磁路，也防止内芯和外芯的接合被释放。版权所有（C）2008，JPO＆INPIT
