PI V-857 High-Speed Direct-Drive Linear Modules
PI V-857 High-Speed Direct-Drive Linear Modules
V-857 is a 132 mm-wide direct-drive linear-stage family for fast industrial positioning. PI identifies an ironless three-phase linear motor, high-precision linear feedback and load capability up to 1000 N. The supplied generic high-speed-module listing corresponds to this V-857 scope, rather than the different 166 mm-wide V-817 platform.
Review Summary
Consider V-857 when high-speed scanning or repeated transfer motion justifies a linear motor and the installation can support its thermal and power demands. The catalog’s 5000 mm/s maximum and 50 m/s² unloaded acceleration are separate upper-limit conditions, not guaranteed simultaneous loaded production performance.
