摘　　要：介绍直线电机的结构原理,分析其在机床进给系统中应用的优越性,设计采用循环液冷却的智能温控系统。样机试验结果表明,使用该智能温控系统能得到满意的冷却效果,解决了因直线电机电磁热引起导轨变形、进而导致位移和速度控制精度下降的问题。The structure and principle of linear motor were showed. Advantages of it in machine tool feeding system were analyzed. The automatic temperature control system using circle fluid cooling was designed. The sample machine experiment results show cooling effect of the system is obvious. The problem that displacement and speed control precision decline due to the lead rail transmutation caused by linear motor＇s electromagnetism heat is solved.
