    • PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a size reduction and a high performance are realized by improving a cooling method.
      SOLUTION: In the rotary electric machine, assuring of a magnetic path by the deflection of a magnetic flux line 25 and enlarging of a region 26 which can be cooled are realized by forming a stator core 23 of a dust core material and adding a collar-like additional region 23a to this stator core 23. The reason why such a constitution is formed is because since a loss heat is generated in response to a magnetic flux in the stator core 23 and simultaneously the heat is added as the current loss of the stator coil 22 itself at the place where the magnetic flux in the stator core 23 is generated around a stator coil 22 from the stator to the magnet of a rotor, it is desired to set a refrigerant channel 26 in the region which surrounds the magnetic flux in the stator core 23. In other words, the stator core 23 is suitable to have the refrigerant channel 26 in the interior or the front surface of the stator core of the region which is not interfered with the dense part the magnetic flux line 25 generated with the stator coil 22, and passing through the interior of the stator core 23.

    • PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a size reduction and a high performance are realized by improving a cooling method.
      SOLUTION: In the rotary electric machine, assuring of a magnetic path by the deflection of a magnetic flux line 35 and enlarging of a region 36 which can be cooled, are realized by forming a stator core 33 of a dust core material and adding a collar-like additional region 33a to this stator core 33. The reason why such a constitution is formed is because since a loss heat is generated in response to a magnetic flux in the stator core 33 and simultaneously the heat is added as the current loss of the stator coil 34 itself at the place where the magnetic flux in the stator core 33 is generated around a stator coil 34 from the stator to the magnet of a rotor, it is desired to set a refrigerant channel 36 in the region which surrounds the magnetic flux in the stator core 33. In other words, the stator core 33 is suitable to have the refrigerant channel 36 in the interior or the front surface of the stator core of the region which is not interfered with the dense part the magnetic flux line 35 generated with the stator coil 34, and passing through the interior of the stator core 33.

    • PROBLEM TO BE SOLVED: To perform more effective motor cooling with a simple structure.
      SOLUTION: In an axial motor 10, stators 16 are arranged opposite to a rotor 14 through a prescribed gap 22. An inlet 24 leading a cooling medium to an inner peripheral side end 22a of the gap 22 is formed in the case 18 of the motor 10. The cooling medium 20 supplied to the inner peripheral side end 22a of the gap 22 from the inlet 24 is transported to an outer peripheral side end 22b of the gap 22 with a rotation operation of the rotor 14. In a process of transportation, the cooling medium removes heat of the rotor 14 and the stator 16. The cooling medium 22 discharged to an outer side of the gap 22 is discharged to an outer part of the case through an outlet 25 arranged at a lower part of the case 18.

    • 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
