针对传统电火花加工中电极间隙难以实时控制的问题，研制了一种电磁驱动器。电磁致动器的线圈中的输入电流产生洛伦兹力，该洛伦兹力导致电极轴向移动。当电磁执行器工作时，电极被快速驱动定位，并通过控制使电极产生± 1mm的位移。实验表明，该电磁驱动器的响应时间能够满足加工要求。提高了放电概率，提高了加工效率。
In this paper, a kind of electromagnetic actuator is developed which can solve the problem of in time controlling inter-electrode gap in traditional EDM. An incoming current in the coil of an electromagnetic actuator generates Lorentz forces that cause the electrode to move axially. When the electromagnetic actuator is working, electrode is actuated positioned quickly, and electrode is produced a displacement of plus or minus 1 mm by control. The experiment shows that the response time of the electromagnetic actuator can meet the machining requirements. The discharge probability is increased and the machining efficiency is improved.
