进给螺杆用于各种工业机器和机器人中，以将旋转运动转换为线性运动。机械螺杆，如滚珠螺杆和滑动螺杆，通过摩擦接触传递力，通过摩擦接触产生噪音和热量;因此，驱动效率降低。为了解决这些问题，我们提出了一些类型的磁导螺杆（MLS）没有螺旋永磁体。该设计没有螺旋永磁体，并且包括相对较少的部件。然而，由于结构差异而导致的推力密度和生产率的差异尚未报道。本文基于三维有限元法的磁场分析，研究和讨论了无螺旋永磁体的MLSs的性能和生产率。在相同的尺寸和基本设计参数下设计了MLSs。的推力和扭矩特性的MLSs的分析结果显示和比较，和他们的生产率进行评估的部件的数量。© 2021日本电气工程师协会。出版社：Wiley Periodicals LLC
Feed screws are used in various industrial machines and robots to convert rotational motions into linear motions. Mechanical screws, such as ball screws and slide screws, transmit force via frictional contacts through which noise and heat are being generated; thus, the drive efficiency is decreased. To address these problems, we have proposed some types of magnetic lead screws (MLSs) without spiral permanent magnets. The design has no spiral permanent magnets and comprises relatively few components. However, the differences in the thrust density and productivity due to the structural differences have not been reported. This paper investigates and discusses the performance and productivity of the MLSs without spiral permanent magnets based on a magnetic field analysis using a three‐dimensional finite element method. The MLSs are designed under the same size and basic design parameters. The analysis results of the thrust and torque characteristics of the MLSs are shown and compared, and their productivity is evaluated by the number of components. © 2021 Institute of Electrical Engineers of Japan.
