    • Disclosed is an optimized brake method for braking a motor rotating at a high speed. When the motor rotates at the high speed, the present invention reduces the rotation speed of the motor using a mechanical brake method which has a relatively high rate of energy exhaustion, and when the rotation speed of the motor reduces below a predetermined speed, the present invention stops the motor using an electrical brake method. Therefore, since the mechanical brake method is used during the high speed rotation interval, heat occurrence can be prevented, and the electrical brake method is used during the relatively low speed interval so that the motor can be stopped within a short time.
    • 公开了一种用于制动高速旋转的电动机的优化制动方法。 当电动机高速旋转时,本发明使用具有较高的能量耗尽率的机械制动方法来降低电动机的转速,并且当电动机的转速降低到预定速度以下时,本发明 本发明使用电制动方法停止电动机。 因此,由于在高速旋转间隔期间使用机械制动方法,因此可以防止发热,并且在相对低速的间隔期间使用电动制动方法,从而可以在短时间内停止电动机。
