近年来在许多液压伺服系统中常用液压马达作为精密控制的执行元件,而液压伺服系统的品质往往取决于所选用的马达;伺服马达不但要有很低的起动压差和很小的转动惯量,而且要有很宽的调速范围,以便于在系统中对速度的直接控制。国内外出现了不少低速性能良 In recent years, many hydraulic servo systems commonly used hydraulic motors as the precise control of the executive components, and the quality of the hydraulic servo system often depends on the choice of motor; servo motor not only has a very low starting pressure and a small moment of inertia, And to have a wide speed range, in order to facilitate the direct control of the speed in the system. There have been many good low-speed performance at home and abroad
