    • A rotary electric machine comprises a rotating shaft 7 rotatably supported by bearings 2, 3, a rotor 23 attached integrally with the rotating shaft 7, and a stator 5 arranged facing the rotor 23. The stator 5 includes a plurality of coils arranged substantially in a circular (annular) form in a rotating direction of the rotating shaft 7. The rotor 23 includes a circular-disc rotor yoke 26 made of a ferromagnetic material, such as iron. Depressed portions and raised portions 28 on a surface of the rotor yoke 26 facing the stator 5, except for the center portion, are arranged in a circumferential direction of the rotor yoke 26. N-pole magnets 29 and S-pole magnets 30 are alternately arranged in the depressed portions 27. Therefore, in addition to torque generated by the magnets 29, 30, reluctance torque is generated between the raised portions 28 on the rotor yoke side 26 and the teeth on the stator side 25, thus making it possible to increase the range of rotation speeds of the motor.
    • 旋转电机包括由轴承2,3可旋转地支撑的旋转轴7,与旋转轴7一体地安装的转子23和面向转子23设置的定子5。 定子5包括沿旋转轴7的旋转方向大致呈圆形(环形)形状的多个线圈。 转子23包括由诸如铁的铁磁材料制成的圆盘转子轭26。 除了中心部分之外,转子轭26的面向定子5的表面上的凹陷部分和凸起部分28布置在转子轭26的圆周方向上。 N极磁铁29和S极磁铁30交替排列在凹部27中。 因此,除了由磁体29,30产生的转矩以外,在转子轭侧26的凸部28与定子侧25的齿之间产生磁阻转矩,能够提高转子轭 电机。

    • A cooling device suitable for cooling a laser diode bar constituting a surface illuminating device as a light source for exciting a laser medium of a solid-state laser oscillator of high power. The cooling device is capable of flowing coolant at sufficient flow rate by reducing the pressure loss in the flow passage of the coolant in the device, to realize a light source device of small thickness with high cooling capability and high reliability. The cooling device comprises a first plate member, one or more second plate member and a third plate member to be joined together to form a laminated body. The second plate member has grooved paths formed on both surfaces thereof and having depths greater than a half of thickness of the plate member, and also opened paths for communicating grooved paths formed on the first plate member and the third plate member. The pressure loss in the flow passage of coolant is reduced by increasing a sectional area of the flow passage by the grooved paths and the opened path of the second plate member without lowering mechanical strength of the device and without increasing a manufacturing cost of the device.
    • 一种适于冷却构成表面照明装置的激光二极管条的冷却装置,作为用于激发高功率的固态激光振荡器的激光介质的光源。 冷却装置能够通过减小装置内的冷却剂的流路中的压力损失,以足够的流量流动冷却剂,实现具有高冷却能力和高可靠性的小厚度的光源装置。 冷却装置包括第一板构件,一个或多个第二板构件和第三板构件,以将其接合在一起以形成层压体。 第二板构件具有形成在其两个表面上并且具有大于板构件的厚度的一半的深度的凹槽路径,以及用于连通形成在第一板构件和第三板构件上的沟槽路径的开口路径。 通过在不降低装置的机械强度的情况下增加通过槽形路径和第二板构件的打开路径的流动通道的截面积而减小冷却剂的流动通道中的压力损失,并且不增加装置的制造成本。
