    • A cooling device for an electrical rotating machine is provided. The cooling device comprises; a yoke of an electric motor, end brackets and a rocker positioned in the outer circumferential portion of a commutator and fastened through the mediary of ventilation spaces to the inner circumference of one of the aforesaid end brackets. The cooling device further comprises; a screening plate for controlling the direction of cooling air being blown and a strength thereof, which is disposed between one end of the aforesaid rocker and the yoke; and a forcibly blowing device. With this cooling device, the cooling air is introduced through ventilating spaces defined radially inwardly of the aforesaid one end bracket into an electric motor by the forcibly blowing device, thereby forcibly cooling the surface of the commutator and the peripheral portion thereof.

    • Stator claw poles are disposed at a stator core at a position facing opposite a rotor so as to alternately range from the two sides along the axial direction. With a plurality of magnetic poles thus formed, the distance by which the gap between the front end portions of the stator claw poles and the stator outer circumference ranges is increased, which, in turn, reduces the reactance guided to a stator coil. It is ensured that the magnetic reluctance manifesting between the front end portions of the stator claw poles and an enclosing member that holds the stator core, facing opposite the centers of the claw poles along the circumferential direction, is greater than the magnetic reluctance manifesting between the front portions and the stator core enclosing member facing opposite the front end portions.
    • 定子爪极在与转子相对的位置处设置在定子芯上,以便沿着轴向从两侧交替地范围。 通过这样形成的多个磁极,定子爪极的前端部和定子外周的范围之间的间隙的距离增加,这又减小了引导到定子线圈的电抗。 确保在定子爪极的前端部和保持定子铁芯的围绕着爪极的中心的圆周方向相对的磁阻大于磁轭的磁阻, 前部和定子芯包围构件面对着前端部分。

    • The present invention supplies a position detection circuit, and a motor controller, that can not only obtain rotor position detection signals properly over the entire PWM control region, but also obtain these signals properly during PAM control. In a brushless motor controller based on the present invention to detect the magnetic pole position of the stator in the motor in accordance with the stator coil terminal voltages of multiple phases and control the energization of the stator coils, the comparison result information signal, after being obtained through comparison between the detected voltage values corresponding to the foregoing terminal voltages, and a reference voltage value, is directly entered into control circuits, then the position of the rotor in the motor is properly detected immediately after power-on switching, without a rotor position detection inhibition time interval being provided, and the motor is controlled properly.
    • 本发明提供一种位置检测电路和电动机控制器,其不仅可以在整个PWM控制区域上适当地获得转子位置检测信号,而且还可以在PAM控制期间适当地获得这些信号。 在基于本发明的无刷电动机控制器中,根据多相的定子线圈端子电压来检测电动机中的定子的磁极位置,并且控制定子线圈的通电后的比较结果信息信号 通过将对应于前述端子电压的检测电压值与基准电压值进行比较而获得的电压直接输入到控制电路中,则在通电切换之后马达中的转子位置被适当地检测到,而没有转子 提供了位置检测禁止时间间隔,并且电机被适当地控制。
