摘要:
A motor control system that reduces noise while reducing power requirements but providing sufficient torque. A one-phase-on drive mode modified to microstep between "one phase on" positions is used to accelerate the motor in a non-linear manner to a maximum speed. The microstep drive modes have a constant period, and the step rate of the motor is increased by decreasing the number of microsteps in succeeding steps of the motor. A modified full step waveform maintains the motor at the maximum speed, where the current to one winding of the step motor changes polarity within one motor step while the other remains approximately constant providing increased smoothness in the drive and reduced noise. The polarity changes in accordance with the inductance and the compliance voltage of the motor. A one-phase-on waveform modified to include microsteps between "one phase on" positions later decelerates the motor in a non-linear manner, and the motor stops in a detent position until another waveform of steps in delivered to the motor.
摘要(中):
一种电机控制系统,可减少噪音,同时降低功率需求,但提供足够的扭矩。 在“一相”位置之间修改为微步的单相驱动模式用于以非线性方式将电动机加速到最大速度。 微步驱动模式具有恒定周期,并且通过减少马达的后续步骤中的微步数量来增加马达的步进速率。 改进的全步波形将电动机保持在最大速度,其中步进电机的一个绕组的电流在一个电动机阶跃期间改变极性,而另一个保持大致恒定,从而提高驱动器的平滑度和降低的噪声。 极性根据电机的电感和顺从电压而变化。 修改为包括“一相”位置之间的微步的单相接通波形稍后以非线性方式使电动机减速,并且电动机停止在制动位置,直到传递到电动机的另一个步骤波形。
