摘要： PROBLEM TO BE SOLVED: To improve the efficiency of an electric motor having a split core.
SOLUTION: A core 20 split with a foundation portion 32 split and an erect portion 34 are fastened with bolts 36. This brings a joint surface 46 of the foundation portion 32 to the erect portion 34 into close contact with each other, thus reducing magnetic resistance and improving efficiency. The bolt 36, made of non-magnetic material, reduces the number of magnetic fluxes passing through the bolt, thus reducing an eddy current developed in the bolt. Moreover, a ratio (H/D) of a distance H between a teeth front end face 48 and a bolt head top face 50 to a diameter D of a bolt hole is set at ≤0.3.

摘要： 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.

摘要翻译：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

摘要： 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.

摘要翻译：要解决的问题：提供通过改进冷却方法来实现尺寸减小和高性能的旋转电机。解决方案：在旋转电机中，通过磁通线25的偏转确保磁路的径向，并且可以冷却的区域26的扩大通过形成防尘芯材料的定子芯23并添加形成该定子铁芯23的轴环状附加区域23a。形成这种结构的原因是因为由于在定子铁心23中响应于磁通量而产生损耗热量，同时加上热量作为电流损耗定子线圈22本身在定子铁心23的磁通量从定子绕转子的定子线圈22周围产生的位置处，因此希望将制冷剂通道26设置在围绕定子铁芯23中的磁通量。换句话说，定子铁心23适于将制冷剂通道26设置在不干扰密实部分的区域的定子铁芯的内部或前表面中，磁通量 ne 25与定子线圈22产生并穿过定子芯23的内部。版权所有：（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To attain an effective operation in an inverter system provided with two inverters. SOLUTION: A three-phase motor currents are fed to a correction voltage addition/subtraction judging section 102. The addition/subtraction judging section 102 judges whether two of the three-phase motor currents are positive or not. If two are positive, a positive correction voltage ΔV is fed to an adder 104 and if two are negative, a negative correction voltage ΔV is fed to the adder 104. Output from the adder 104 is the voltage command value of a motor and the neutral voltage of the three-phase motor is corrected by adding the correction voltage. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an axial type motor capable of reducing the support rigidity of a rotor, with regard to the axial direction of a rotor shaft, using a simple structure.
SOLUTION: A second stator 14, constituted of a strong magnetic body, is disposed opposite to a first stator 12 in the axial direction of the rotor shaft, where the first stator 12 and the second stator 14 are disposed so as to face each other holding the rotor 10 in between in the rotary shaft direction. Neither teeth projecting to the rotor 10 side nor coil for applying torque to the rotor 10 are provided to the surface 14-1 which faces the rotor 10 in the second stator 14. A suction force, the direction of which is opposite to that of the suction force working between the rotor 10 and the first stator 12, acts between the rotor 10 and the second stator 14, enabling the suction force applied to the rotor 10 to be reduced.

摘要： PROBLEM TO BE SOLVED: To efficiently cool a rotor of an axial permanent magnet motor, especially a permanent magnet.
SOLUTION: An air channel 36 where a fluid such as air flows is formed between permanent magnets 34 constituting the magnetic pole of a rotor 30. The air channel 36 is provided almost in the radial direction of the rotor 30, and the fluid in the channel flows under the action of a centrifugal force when the rotor rotates. Thus, cooling is carried out near the permanent magnet, which heats more, inside the rotor, and the generated heat is promptly exhausted, while the heat radiation area of the rotor increases for more efficient cooling.
