The GO-M8010-6 is a Unitree brushless outrunner motor designed as a quasi-direct-drive (QDD) joint actuator for Unitree quadrupeds. Its 36-slot stator and 42-pole rotor with delta winding deliver very high torque density and low cogging torque, which is why only a short, low-ratio planetary reducer is needed for precise leg control.
The motor is used at series scale in the hip, knee and ankle joints of Unitree Go1 and Go2, as well as in the larger B1 platform. Paired with an absolute encoder and an integrated FOC controller it enables low-impedance torque control — essential for dynamic running, jumping and impact-tolerant balance recovery.
BLDC Motor · serves as: Joint Actuation, Locomotion Drive, Motion Generation, Closed-Loop Drive Control. · compatible with: Quadruped, Legged Robot, Research Robot.
Which group Unitree GO-M8010-6 belongs to and how it is built
The BLDC (Brushless DC) motor is widely used in robotics due to its high efficiency, long service life, low mechanical wear, and the ability to precisely control speed and torque. BLDC motors are found in robot joints, grippers, dexterous hands, cooling fans, and mobile platforms. Combined with an appropriate controller and encoder, they form the foundation of modern electric drive systems.
