【摘要】 结合高速切削需求,详细阐述了高速数控机床选用永磁直线同步电动机(PMLSM)的计算和校验过程,并分析了选型过程中应该注意的事项。直线电动机不经过任何机械转换装置直接产生直线运动,提高了驱动系统的进给速度、加速度、刚度和定位精度,而且结构简单,噪声低,无直接机械磨损,故其在高速度、高精度数控机床进给驱动系统中的应用日益广泛。更多还原

【Abstract】 Based on the demand of high-speed cutting,it presents the computation and the verification process of Permanent Magnetic Linear Synchronous Motor(PMLSM) to Computer Numerical Control(CNC) machine tools in detail,gives some key items to apply the motor.Linear motor can accomplish the linear movement without any intermediate conversion device,and enhance the actuation system feed rate,the acceleration,the rigidity and the pointing accuracy,moreover the structure is simple,the noise is low,prevents directly machinery wearing.更多还原
