摘要： An inner-rotor-type motor includes a housing, a stator, a rotor, a permanent magnet and a cover plate. The housing has a compartment. The stator is received in the compartment. There is an assembling hole arranged at the axial center of the stator and passing through the stator from the top to the bottom thereof. The rotor has a shaft with one end thereof rotatably extending through the assembling hole, with a bearing being mounted around the shaft. The permanent magnet is fixed to an outer periphery of the shaft and beside the bearing, with the permanent magnet facing the stator. The cover plate is arranged between the permanent magnet and the bearing. Consequently, impurities are prevented from entering an undesired interstice between the bearing and the shaft or from entering the inside of the bearing, such that smooth rotation of the rotor is provided and such that life of the inner-rotor-type motor is extended.

摘要： A brushless dc motor includes a PWM drive IC member, a Hall IC member, a PWM converter circuit and a Rotational Detection (RD) signal line. The PWM drive IC member electrically connects with the Hall IC member, the PWM drive IC member further includes a pin electrically connected with the PWM converter circuit. The RD signal line connects between the pin of the PWM drive IC member and the PWM converter circuit, and further connects with a RD signal source to supply RD signals to the pin of the PWM drive IC member. When the motor is jammed, the jammed RD signals can build a predetermined voltage which can determine the PWM drive IC member to be restarted or operated at a predetermined-speed mode. In this circumstance, no inrush current of the jammed motor will occur.
摘要翻译：无刷直流电动机包括PWM驱动IC部件，霍尔IC部件，PWM转换电路和旋转检测（RD）信号线。 PWM驱动IC元件与霍尔IC元件电连接，PWM驱动IC元件还包括与PWM转换电路电连接的引脚。 RD信号线连接在PWM驱动IC部件的引脚和PWM转换电路之间，并与RD信号源连接，将RD信号提供给PWM驱动IC部件的引脚。当电机卡住时，卡住的RD信号可以建立一个预定电压，该电压可以确定PWM驱动IC元件被重新启动或以预定速度模式运行。在这种情况下，不会发生卡住电机的浪涌电流。
