    • A frequency of a power supply applied to a stepping motor changes in accordance with a predetermined program to control the stepping motor such that a predetermined rotational speed of the motor is quickly obtained without generating noise. The power supply frequency is abruptly and linearly increased or decreased within an initial predetermined time interval. A high accelerating or decelerating torque is applied to the stepping motor to obtain a first rotational speed for a short period of time. Thereafter, the power supply frequency is exponentially decreased or increased within a final predetermined time interval to obtain a second rotational speed at which the noise level is low.
    • 施加到步进电动机的电源的频率根据预定程序而改变,以控制步进电动机,从而快速获得电动机的预定转速而不产生噪声。 电源频率在初始预定时间间隔内突然和线性地增加或减少。 对步进电机施加高加速或减速转矩,以在短时间内获得第一转速。 此后,电源频率在最终预定时间间隔内以指数方式减小或增加,以获得噪声电平较低的第二转速。
