摘要： Starting, accelerating and rated rotation of a rotor is carried out without any detector for the rotor position. A motor is controlled with an openloop circuit a short time in a starting area of low speed rotation, and thus the motor can be certainly started. In a rated rotation area, turning timing of the motor is precisely controlled by detecting counter-electromotive force of a stator coil.
摘要翻译：不用转子位置的任何检测器就能进行转子的起动，加速和额定转速。在低速旋转的起始区域中，电动机在短时间内由开环电路控制，因此电动机可以肯定地起动。在额定旋转区域中，通过检测定子线圈的反电动势来精确地控制电动机的转动正时。

摘要： A battery charger and a charge controller therefor are disclosed, the battery charger including a supply circuit for supplying a charging current to a battery and a control circuit for controlling the supply of the charging current to the battery. The control circuit shuts the charging current when the detected voltage of the battery is smaller than the maximum peak value by a predetermined quantity. A control means shuts the charging current after a predetermined time has elapsed from a time at which the detected voltage of the battery has raised to the maximum peak value. The control means reduces the charging current when the detected voltage of the battery is made to be a switching voltage. Furthermore, the control means shuts the charging current after a predetermined time has elapsed after the charging current had been reduced.
摘要翻译：公开了一种电池充电器及其充电控制器，电池充电器包括用于向电池供应充电电流的供电电路和用于控制向电池供应充电电流的控制电路。当电池的检测电压小于最大峰值预定量时，控制电路关闭充电电流。在从电池的检测电压上升到最大峰值的时间经过了规定时间后，控制装置关闭充电电流。当电池的检测电压为开关电压时，控制装置减小充电电流。此外，控制装置在充电电流减小之后经过了预定时间后关闭充电电流。

摘要： A fan motor has a pair of ball bearings placed in the vicinity of each end of an inner side of a bearing race. A plurality of projections are sequentially placed circumferentially around a center portion of the bearing race to axially locate both the ball bearings. A plurality of low-profile projections are sequentially formed between neighboring projections on the inner side surface of the bearing race and are axially elongated from one installing position to that of another installing position of respective ball bearings. The ball bearings are supported by the inner side of each low-profile projection respectively at one end portion and the other end portion of the low profile-projections.
摘要翻译：风扇马达具有放置在轴承座的内侧的每个端部附近的一对滚珠轴承。多个突起沿圆周方向依次放置在轴承座的中心部分上以轴向定位两个滚珠轴承。在轴承座圈的内侧表面上的相邻突起之间依次形成多个低轮廓突起，并且从一个安装位置轴向延伸到相应球轴承的另一个安装位置。球轴承分别在低轮廓突起的一个端部和另一个端部处由每个低轮廓突起的内侧支撑。
