Cycloidal Pinwheel Joint Motor 91 · 660W with Brake
The cycloidal pinwheel joint motor (with brake) integrates a frameless torque motor, cycloidal pin-wheel reducer, encoder, and a 24V brake with backlash under 3 arcmin. Widely used in robotic arms, humanoid robots, and multi-legged robots.
The cycloidal pinwheel joint motor (with brake) is a highly modular and integrated actuator incorporating a frameless torque motor, a cycloidal pin-wheel reducer, an encoder, and a 24V brake. The reducer delivers backlash under 3 arcmin and 125 N-m rated torque, giving high repeatability and shock resistance; the power-off brake holds the output position for fail-safe vertical-axis applications. Operating temperature is -40 to +65 degrees C. Widely used in robotic arms, humanoid robots, and multi-legged robots.
