Dual Rail, Linear Servo Motors

The DR (dual profile rail) positioning stages are a series of low cost, stable, linear motor driven stages with travel lengths to 160". These wide footprint - up to 15.6" - brushless linear motor stages have large load capabilities of 442 lb, high continuous force to 445 lb/1,978 N (1,335 lb/5933 N peak force), high resolution to 0.00004", high velocity up to 200ips, and acceleration up to 9G's.

The DR positioning stages are ideal for use as the base or X axis in stacked multi-stage (X-Y and X-Y-Z) applications for: vision inspection, pick-and-place, robotics, assembly, packaging, parts transfer, testing, semiconductor manufacturing, and clean room applications.

The DR positioning stages are supplied with a non-contact, three-phase brushless linear motors commutated either sinusoidally or trapezoidally with Hall effect sensors. Available options include: matching servo amplifiers and controllers; a high resolution, non-contact glass or metal scale; and optical encoder or magnetic linear encoders with reference mark for homing. Water cooling doubles the continuous force to 890 lb/3,956 N, custom mounting holes (on base and stage), and a large easy access cable carrier that can accommodate additional cables and hoses. Typical encoder output is A and B square wave however sinusoidal output is available. These custom high performance stages have very short lead times.
