    • A drive apparatus is disclosed which is designed to switch/excite a plurality of excitation windings of a stepping motor in a predetermined order. Periodic velocity fluctuation data of the stepping motor is stored in a memory unit in advance. An arithmetic unit reads out the velocity fluctuation data stored in the memory unit. The arithmetic unit outputs a pulse train whose pulse rate fluctuates to have a phase opposite to that of velocity fluctuation obtained from the velocity fluctuation data. This pulse train is used as switching timing signals for switching/exciting the plurality of excitation windings in a predetermined order.
    • 公开了一种驱动装置,其被设计成以预定顺序切换/激励步进电机的多个励磁绕组。 预先将步进电机的周期性速度变动数据存储在存储器单元中。 算术单元读出存储在存储单元中的速度波动数据。 运算单元输出脉冲波动的脉冲串,与从速度变动数据得到的速度波动相反。 该脉冲串用作用于以预定顺序切换/激励多个励磁绕组的开关定时信号。
