    • A motor controlling device includes an encoder to output pulse signals with a predetermined angle interval as a rotor of a motor is rotated. An energized phase of the motor is sequentially switched by detecting a rotation position of the rotor based on a value of counting the signals. An initial drive controlling portion executes an initial drive to switch the energized phase with a predetermined pattern after the device is activated so as to learn a relationship among the count value, the rotation position and the energized phase. An initial drive prohibiting portion prohibits the execution of the initial drive until a predetermined time is elapsed after the initial drive is finished.
    • 电动机控制装置包括编码器,当电动机的转子旋转时,输出具有预定角度间​​隔的脉冲信号。 基于对信号进行计数的值,通过检测转子的旋转位置来依次切换电动机的通电相位。 初始驱动控制部分在器件启动之后执行初始驱动以切换具有预定图案的通电相位,以便学习计数值,旋转位置和通电相位之间的关系。 初始驱动禁止部分禁止执行初始驱动,直到在初始驱动完成之后经过预定时间。

    • A plurality of concavities and convexities is provided on tips of all rotor teeth 24 of the SR motor 5. Depths of the concave portions α are deep on an edge side where a stator tooth 23 and rotor tooth 24 first approach and are shallow as a facing area between the stator tooth 23 and rotor tooth 24 increases. Therefore, magnetic resistance between the stator tooth 23 and rotor tooth 24 becomes high at an early stage of the stator tooth 23 and rotor tooth 24 facing each other and becomes low as the facing area between the stator tooth 23 and rotor tooth 24 increases. As a result, torque fluctuation can be suppressed at a time of a large current and a minimum generation torque can be increased at a time of a small current.
    • 在SR马达5的所有转子齿24的尖端上设置多个凹凸。凹部α的深度在定子齿23和转子齿24首先进入并且浅的面的边缘侧是深的 定子齿23与转子齿24之间的区域增加。 因此,定子齿23和转子齿24之间的磁阻在定子齿23和转子齿24彼此面对的早期变高,随着定子齿23和转子齿24之间的相对面积的增加而变低。 结果,可以在大电流时抑制转矩波动,并且可以在小电流时增加最小的发电转矩。
