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.
Frameless Torque Motor
The frameless torque motor, a specialized type of permanent magnet synchronous motor (PMSM), consists of two core components: the rotor and stator, while eliminating traditional motor structures such as housings, bearings, and shafts. Designed for direct integration into a customer’s mechanical system, it requires the end-user to supply supporting bearings and enclosures. This design philosophy delivers higher flexibility, more compact dimensions, and superior performance, making it ideal for applications with stringent demands on space, weight, and dynamic capabilities. It excels in high-precision, high-dynamic-response scenarios, including humanoid robot joint actuation, precision rotary stages, medical equipment, and industrial automation systems.Frameless torque motors are further subcategorized into internal rotor frameless motors and external rotor frameless motors, depending on their structural configuration.

FMK Highly Integrated Robot Joint Frameless Torque MotorsFrameless torque motors, unlike traditional servo motors, consist only of stator and rotor components. Compared to framed motors, frameless motors offer flexible configuration and easy installation. Considering the increasing trend of highly integrated drive systems, frameless motors better meet the expectations of engineers. Engineers no longer need to consider motor interfaces in system design, allowing for maximum reduction of space occupied by the power output unit in the drive system, leading to higher system integration.The HONPINE FMK frameless torque motors are now widely used in the J1–J6 joints of collaborative and dual-arm robots, the walking joints of quadruped robots, and the flexible joints of humanoid robots.Details![Dynamic Response High Torque Density External Rotor Frameless Torque Motor]( "Dynamic Response High Torque Density External Rotor Frameless Torque Motor")
Dynamic Response High Torque Density External Rotor Frameless Torque MotorThe external rotor frameless torque motor is a specialized type of permanent magnet synchronous motor (PMSM) composed of two core components: the rotor and stator. Unlike traditional internal rotor designs, this motor features an externally mounted rotor and an internally positioned stator. The innovative design eliminates traditional motor housings, bearings, and shafts, retaining only the rotor and stator assemblies. The rotor, located outside the stator, integrates permanent magnets with the outer shell and is directly embedded into the load structure. The stator, positioned internally, contains copper windings and laminations, driving the external rotor’s rotation via electromagnetic forces. This design combines the high moment of inertia of the external rotor configuration with the compactness of the frameless structure, making it ideal for applications requiring low-speed high-torque output and efficient heat dissipation, such as medical equipment, industrial fans, and automated industrial systems.Details![Compact Lightweight High Power Density Internal Rotor Frameless Torque Motor]( "Compact Lightweight High Power Density Internal Rotor Frameless Torque Motor")
Compact Lightweight High Power Density Internal Rotor Frameless Torque MotorThe internal rotor frameless torque motor is a specialized type of permanent magnet synchronous motor (PMSM) composed of two core components: the rotor and stator. The rotor is internally positioned, while the stator is externally mounted. Its innovative design eliminates traditional motor housings, bearings, and shafts, retaining only the rotor and stator assemblies. The rotor typically adopts a ring-shaped structure integrated with permanent magnets, directly mounted on the load shaft. The stator consists of copper windings and laminations, generating electromagnetic forces to drive rotor rotation. This configuration achieves torque output through efficient magnetic field interaction, making it ideal for high-precision applications such as robotic joints and industrial automation. It enables direct load driving, minimizing mechanical transmission losses.Details
