Cost effective linear stages on roller guide

Stage consist of a movable solid iron core with rollers, encoder head and epoxy encapsulated windings (forcer) and fixed steel plate with guide shafts, encoder band and glued permanent magnets (stator). The smoothness of movement is achieved by sinusoidal commutation of motor phases currents.

Available strokes: S =101+64*n mm, where n=1..14; Stage length: L=S+137mm. Cables length is 3 m. Use 4xM4-6H threaded holes for load mounting to forcer carriage; use all Ø4.5/Ø8x4.4 holes for stator mounting to machine stand. To assembly stages to gantry or cross table adjust right angle with precise corner and tight upper stage trough it’s stator holes with 4 screws M4-10 DIN912 strength 8.8 to lower stage’s carriage thread holes crosswise in 3 stages to 40%, 70%, 100% of max torque 2,3Nm. For short strokes axis can be overturned (fixed carriage with windings and cables, movable stator with magnets), screw carriage by 4xM4 threads to stand, and load by 4xØ6.6/Ø11x6.4 holes to stator. Attention: only attraction force 500N forcer’s iron core to stator’s magnets prevents backlash and holds carriage rollers on linear guide shafts, do not apply force over 500N away from stator and tilting torque 23Nm, else carriage will be loose from guide
