利用永磁励磁结构电磁冲击实现微驱动的原理,研制了尺寸为十毫米级任意行程亚微米步距的驱动器,可用作电加工机床的伺服进给装置,配以相应的控制系统和小型脉冲电源即构成完整的微小型电火花加工装置。
Using the principle of micro-drive by electromagnetic impact of permanent magnet excitation structure, a driver with submicrometer step of any stroke of ten millimeters was developed. It can be used as the servo feeding device of electrical processing machine, with the corresponding control system and small pulse The power supply constitutes a complete miniature EDM unit.
