High Speed Rigid Compact Planetary Joint Motor The planetary joint motor is also a core component of robotic power systems. Compared to harmonic joint modules, it features a smaller reduction ratio, higher output speed, and greater rigidity, though with slightly lower overall output accuracy. Through highly integrated components including planetary reducers, frameless torque motors, brakes, encoders, and drivers, its size and weight are significantly optimized, enabling precise joint motion control. This results in higher torque, more compact dimensions, and lighter weight. Planetary joint motors typically support a wide voltage range, adapting to low-voltage DC 24V~48V. We also offer customized solutions based on individual customer requirements.
