The single on-off control of linear induction moter,DC motor and electromagnet is implemented by using data acquisition card digital I/O port. At the meantime the linear motor voltage and frequency are controlled by the D/A output of data acquisition card.
同时利用数据采集卡的数字I/O口,实现对直流电机、直线电机和电磁铁的简单开关控制,采用两路D/A输出,实现了直线电机电压和频率的数值控制。
