    • PROBLEM TO BE SOLVED: To improve the efficiency of coil cooling by effectively transmitting the heat that a coil generates to the iron core of a stator.
      SOLUTION: Smoothing is performed for a face at which the bundle 14a of coils contacts with a stator iron core (b). For this smoothing, it will do to process it to such a degree that it does not break the insulating film 18 of a rectangular coil 16, leaving an insulating material at the smoothed face of the bundle 14a of coils, or it will do to process it so far as to remove the insulating film 18 of the rectangular coil 16, and then to form an insulating film on this processed face. As regards the formation of the insulating film on the smoothed face, it will do to so form an insulating film 19 as to cover the entire bundle 14a of coils by wrapping, for example, an insulating tape, etc. (c), or it will do to form an insulating film 20 anew only on the smoothed face (d). Since the bundle 14a of coils where smoothing is applied can transmit heat efficiently when contacting with the stator iron core, the efficiency of coil cooling is improved.

    • 要解决的问题:通过有效地将线圈产生的热量传递给定子的铁芯来提高线圈冷却的效率。 解决方案:对于线圈束14a与定子铁芯(b)接触的面进行平滑。 为了平滑化,将其处理到不会破坏矩形线圈16的绝缘膜18的程度,在线圈束14a的平滑表面留下绝缘材料,或者将其进行处理 除去矩形线圈16的绝缘膜18,然后在该加工面上形成绝缘膜。 关于在平滑面上形成绝缘膜,它将会形成绝缘膜19,以便通过缠绕例如绝缘带等来覆盖线圈的整个束14a(c),或者 将仅在平滑的面(d)上再次形成绝缘膜20。 由于施加平滑化的线圈束14a可以在与定子铁芯接触时有效地传递热量,所以提高了线圈冷却效率。 版权所有(C)2005,JPO&NCIPI
