Five profile single-axis positioning stages have been added to the AQ150 series of linear stages. Available off-the-shelf in travel lengths of 600 mm (23.622 in), 700 mm (27.559 in), 800 mm (31.496 in), 900 mm (35.433 in) and 1,000 mm ( 39.370 in.), these stages are available with either a two-phase stepper motor or a three-phase brushless motor with a quadrature incremental optical encoder. Stepper motor-driven models feature a resolution of 2.1 micron. The knob on the stepper motor series can be replaced with an optical encoder for position verification. For closed-loop operation, high precision, higher travel speeds and greater throughput, the stepper motors are replaced with three-phase brushless servo motors and quadrature encoders.
