OES (Optimal Engineering Systems, Inc.) has added two larger rotary stages to their AY110 Series of motorized rotary stages. The low-profile 400 mm AY110-400-01 (step motor driven) and AY110-400-02 (servo motor driven) rotary stages feature a 180 mm (7.087 in.) open aperture. The height of the stage is just 71 mm (2.795 in.). A precise pattern of 16 threaded holes in two bolt circles allows for easy mounting of custom tooling and fixtures, and easily accessible mounting holes in the base are for easy integration into new and existing applications.
The diameter of the rotary table is 400 mm (15.748 in.) and the range of travel is a full 360˚ of continuous rotation. The table is driven by a smooth 360:1 worm gear and has a resolution of 0.0005˚ (18 arcsec) with a 10 micro-steps per step stepper motor driver and repeatability is +/- 0.02˚ (72 arcsec). The AY110-400 rotary stages also feature positional accuracy of +/- 0.05˚, surface roundness of 20 microns and parallelism of 120 microns.
The AY110-400-01 rotary stage is equipped with a stepper motor and a knob for manual adjustment which can be replaced with an optical encoder for precision position verification. The AY110-400-02 rotary stage is fitted with a dc servo motor and quadrature incremental encoder for closed-loop operation. These black anodized stages have a load capacity of 75 kg (165.3 lb). Each of the stages can be ordered plug-and-play with a fully compatible controller from OES.
