DRT-100™ Rotary Table Direct Drive Rotary Table Features : : Speeds to 10 revolutions per second : : 2 micro-radian (0.4 arc-second) resolution : : No gear wear, torque variations, or backlash : : Ultra-stiff 4 point contact ball bearing : : 25mm through-bore Danaher Precision Systems’ DRT-100 Rotary Stage is an ultra-compact, direct drive rotary table that establishes a new level of price, performance, and compactness. Its direct drive technology eliminates the gear wear, torque variations, and backlash conventional rotary tables encounter. Speed, resolution, and repeatability are also increased by a factor of ten or more over gear driven rotary tables. Despite its high level of performance, the DRT-100 Stage is very compact, with body dimensions of 105mm x 105mm x 65mm. Its 25mm through-bore allows convenient routing of optical beam paths or vacuum/pneumatic lines. The DRT-100 Table offers a standard resolution of 20 micro-radians (~4 arc-seconds, or 0.0011 degrees); due to its direct drive technology, the repeatability is +/- 1 count, or +/- 20 micro-radians. Speeds to 10 revolutions per second, and accelerations to 400 revolutions per second2, permit rapid pointto-point moves. Settling times are minimized due to the direct drive design, which allows high servo bandwidths to be achieved. Unlike other direct drive rotary tables, the electronic interface is completely standard, with digital A Quad B encoder outputs, a standard three phase brushless motor, and three digital Hall commutation sensors. This allows the DRT-100 Stage to be driven by any commercial motion controller/amplifier that can drive standard three phase brushless motors. The ultra-stiff 4 point contact ball bearing provides a high degree of axial and torsional stiffness, and a once per revolution index sensor allows a unique home location to be defined.
