RT-3 Motorized Rotary Stage

The RT-3 Series rotary stage is machined from 6061 aluminum alloy to provide a light yet stiff and stable platform.

The RT-3 has a low profile coming in at just over 2″ thick. This rotary stage is to interface with a Nema 17 motor which can be factory installed or installed by the customer. The RT-3 utilizes a worm gear drive with a gear ratio of 90:1. The worm gear is preload to minimize the backlash in the gear train.
