摘要： PROBLEM TO BE SOLVED: To attain low vibration and a low noise while utilizing reluctance torque.
SOLUTION: A rotating electric machine includes a rotor 3 with a plurality of permanent magnets 5 arranged to a rotating shaft 2 in a cylindrical face of the same shaft as the rotating shaft; and a stator 6 which has an annular stator core 7 placed to the rotating shaft 2 on the same shaft as the rotating shaft, and an annular coil to magnetize the stator core 7. The stator core includes an annular portion to cover and fit the annular coil, a plurality of clicks which are arranged at equal intervals on an inner diametrical face of the annular portion and are extended in an axial direction, and a plurality of magnetic gaps formed between the clicks. The number of the clicks is equal to the number of the permanent magnets 5. There is more magnetic flux of a direction intersecting perpendicularly at an electrical angle to a central axial direction than magnetic flux of the central axial direction, which is generated by each permanent magnet 5 between the permanent magnets and the adjoining permanent magnets 5. In order to attain such constitution, metal interpolar auxiliary poles 15 are provided between the permanent magnets 5.

摘要： PROBLEM TO BE SOLVED: To improve the space factor of coils by solving a problem that, usually when coils are formed by winding in an annular shape, one draw-out line can be drawn to the outside out of a portion near the outside circumference of a stator but the other draw-out line is drawn to the outside out of the inside circumference of the stator, so that the draw-out line occupies a part of an inner space formed of a stator core and the space factor of the coils is reduced in a motor comprising claw poles.
SOLUTION: A space through which the wiring of a plurality of coils is passed through is formed in a part of the claw type magnetic poles of the stator core of the stator comprising the claw poles. Thereby, the draw-out line is constituted to draw out in the axial direction one draw-out line of the coils from the outside circumference (or the opposite side which is not the side facing a rotor) of the stator and the other draw-out line from a space of the claw poles of the stator. As a result, an influence by the draw-out line can be eliminated, the number of turns of the coils can be increased even in the same space, and the motor can be miniaturized.

摘要翻译：要解决的问题：为了通过解决通常当线圈通过卷绕成环形形成线圈时可以将一个拉出线从外部附近的部分拉出的问题来提高线圈的空间系数定子的外周，而另一个引出线从定子的内周拉出到外侧，使得拉出线占据由定子铁芯形成的内部空间的一部分，空间因子在包括爪极的马达中减少线圈。解决方案：在包括爪极的定子的定子芯的爪型磁极的一部分中形成有多个线圈的布线通过的空间。由此，引出线构成为从定子的外周（或不是面向转子的一侧的相反侧）沿轴向抽出线圈的一个引出线，从定子的爪极的空间排出线。结果，可以消除引出线的影响，即使在相同的空间中也可以增加线圈的匝数，并且电动机可以小型化。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method that can improve the space factor for winding, even if a motor does not have such a structure that winding space does not have a substantially oblong shape that allows easy winding, and even if a drive voltage is low, the diameter of a conductor becomes large, and the number of windings is small, in the motor having claw-shaped teeth. SOLUTION: The claw-pole motor maximized in the winding space factor can be provided by using a rectangular electric wire for a circular coil of the claw-shaped teeth motor, by winding the rectangular electric wire in a shape almost similar to the cross section of the winding space, and by arranging it. Furthermore, a draw-out portion is formed with the shape of a draw-out wire portion left to be in a shape of the rectangular electric wire, as it is, processed into a prescribed connector shape by using methods, such as the press-punching, cutting, welding, and electric discharge machining of the terminal portion of the draw-out portion, and by forming it into a shape that allows exfoliation of coating, significant reduction in man-hours for a terminal connection portion can be made.
