Precision Rotation Stages with Stepper Motors and Closed-Loop Servo Motors / Worm Gear Precision Rotary Stages

High Angular Resolution, Continuous Rotation, High Holding Force, Self-Braking

Motorized worm gear driven rotary tables provide high angular resolution (the worm gear ratio directly multiplies the motor output torque and motor angle resolution) and holding torque. PI offers precision motorized worm gear rotary tables with both stepper motors and closed-loop servo motors with encoder feedback. While open-loop stepper motors are often used for their lower cost and ease of control, closed loop servo motors with encoder feedback provide higher speed, higher accuracy, and repeatability. PI also provides closed-loop stepper motor rotary stages, combining the best of both worlds. PI stepper motor rotation stages are provided with stepper motor controllers featuring a micro stepping mode for higher performance. For single axis applications, a compact and very cost effective single axis stepper motor controller is available.

For the best performance and highest velocity, direct-drive rotary stages with torque motors are recommended (link to new Rotary Stage Page with Direct Drive Torque Motors).
