A rotary actuator is an electromechanical (or fluid-powered) device that converts stored energy into a controlled angular displacement. In robot joints, it supplies the commanded torque, speed and position feedback that swing a link to an exact angle—typically within a few milliradians—so the arm can grip, weld, screw or inspect with repeatable accuracy. Brushless servo versions dominate modern robots because they pair high torque density with long, maintenance-free life.

Whether you need a single robotic cell prototype or full-scale factory automation, Norck Robotics engineers are ready to collaborate with you to bring your concept to life.
Norck Robotics engineers analyze your existing processes to provide feedback that enhances efficiency, cost-effectiveness, and productivity for robotic integration.
Choosing an actuator means balancing four key performance metrics against the task.
must exceed peak load and inertia by ~30 % to avoid stalling.
ated RPM must meet cycle-time targets without overheating.
smallest commandable angle (step size or encoder count) dictates positioning granularity.
mechanical play on reversal; aim for <1 arc-min in high-precision assembly, higher values acceptable for coarse motions.
Each technology follows a distinct physical principle to create rotary motion.
brushless motor plus encoder; a closed loop corrects current every microsecond for smooth, continuous rotation, high torque density and sub-degree accuracy.
smart alloy twists in a magnetic field; that strain is amplified through a flexure, giving backlash-free, frictionless rotation with micro-second response.
stator phases fire in sequence; every pulse moves the rotor one fixed step (e.g., 1.8 °), enabling open-loop, self-locking positioning.
