SGR Series – Linear Motor Stage
The SGR Series is a compact direct drive positioning stage integrating a coreless rod linear motor, single linear guide and encoder feedback. Available in four frame sizes with travel lengths from 70 mm to 720 mm, it provides 0.2 μm encoder resolution and repeatability up to ±2 μm for fast, precise point-to-point positioning.
The SGR Series Linear Motor Stage is a compact direct drive positioning module designed for fast, precise point-to-point motion. It integrates a coreless rod linear motor, single linear guide, encoder feedback and aluminium housing into a complete ready-to-integrate stage.
Its direct drive design eliminates mechanical transmission components such as ball screws, belts and couplings. This supports smooth, responsive positioning with reduced backlash, mechanical wear and maintenance requirements.
Four frame sizes are available: SGR30, SGR40, SGR60 and SGR70. The range provides continuous force ratings from 3.1 N to 114.8 N and peak force ratings from 9.3 N to 344.5 N, allowing the required motor performance and payload capacity to be matched to the application.
Available travel lengths range from 70 mm to 720 mm, with customised configurations also available. An integrated grating encoder provides 0.2 μm resolution and repeatability up to ±2 μm for micron-level positioning performance.
The SGR Series offers a simple, economical construction for equipment requiring compact dimensions, high speed and accurate linear positioning.
