Unitree A1 Joint Motor

Product Description

Unitree A1 Motor is the high-torque integrated joint actuator developed for the Unitree A1 quadruped, and is equally suited for use in other large-load robotic platforms requiring powerful, reliable joint actuation. Weighing just 605 g, it delivers a maximum output torque of 33.5 N·m and a maximum joint speed of 21 rad/s, enabling the explosive acceleration and dynamic agility that made the A1 quadruped capable of backflips and 3.3 m/s running. The motor features a highly integrated design combining the motor body and controller in a single unit for plug-and-play installation with no external wiring. High-quality electromagnetic wire with dip paint technology, single-strand copper winding for reduced resistance, and 0.2 mm silicon steel sheets with electrophoresis coating ensure thermal performance, rust resistance, and long service life. Built-in FOC control delivers low torque ripple, low noise, and smooth operation.
