英文摘要：

A kind of machine tool component, a direct-driven magnetic levitation linear feed unit was introduced, including its principle and characteristics. The driving force of the machine tool components was provided by the linear motor, The magnetic levitation technology was used to support and move the workbench. It can meet the requirements of high-speed and high-precision of CNC machine tools. The current research situation of direct-driven magnetic levitation linear feed unit was outlined, and the core issues were analyzed.
