摘要： A method and circuit to stop a spindle motor in the absence of the external supply voltage in which the spindle motor is structured to move a hard disk provided with at least one reading or writing head moved by a voice coil motor, the spindle motor provided with a plurality of coils. The method includes rectifying the backelectromotive force of the spindle motor to produce a braking current, driving the voice coil motor with at least a portion of the braking current until the speed of the spindle motor becomes lower than a predetermined stop speed, and, after the parking of the at least one reading or writing head of the voice coil motor, stopping the spindle motor by short-circuiting the coils of the spindle motor.
摘要翻译：一种在没有外部电源电压的情况下停止主轴电机的方法和电路，其中主轴电机被构造成移动设置有由音圈电机移动的至少一个读/写头的硬盘，多个线圈。该方法包括整流主轴电动机的反电动势以产生制动电流，以至少一部分制动电流驱动音圈电动机，直到主轴电动机的速度变得低于预定的停止速度，并且在停放音圈电动机的至少一个读写头，通过使主轴电动机的线圈短路来停止主轴电动机。
