Frameless Torque Motor FAQs
Understanding how frameless torque motors perform, integrate, and compare to other drive technologies is essential for successful system design. This FAQ provides clear technical guidance on selection, customization, thermal management, control systems, and application suitability for robotics, automation, and advanced mechatronic platforms.
A frameless torque motor consists of only the stator and rotor, allowing integrators to embed it directly into their mechanical structure. This eliminates the housing and shaft constraints of traditional motors, enabling compact integration, lower inertia, and higher torque density.
They excel in robotic joints, humanoid robots, quadruped robots, industrial manipulators, gimbals, medical devices, semiconductor tools, and high-precision automation systems where smooth, direct-drive motion is required.
Selection is based on required continuous torque, peak torque, speed, available installation space, inertia matching, and thermal conditions. Our engineering team can assist with sizing based on your application’s mechanical and electrical requirements.
Continuous torque is the load the motor can sustain indefinitely without overheating.
Peak torque is the maximum short-term torque available for dynamic movements like lifting, acceleration, or stabilization.
Yes. We support customization of windings, stator dimensions, mounting holes, rotor geometry, cable routing, connector types, insulation class, and other mechanical or electrical parameters.
Frameless torque motors work with a wide range of encoders, including absolute, incremental, magnetic, optical, and high-resolution encoders commonly used in robotic joints and precision control systems.
Most BLDC or PMSM servo drivers that support three-phase sinusoidal commutation are compatible. We can recommend suitable controllers depending on your speed, torque, and resolution requirements.
Proper thermal paths are essential. This typically involves bonding the stator to the housing and ensuring sufficient conduction to the frame. We can provide thermal guidelines and integration support for optimal performance.
Direct-drive systems eliminate backlash, reduce mechanical wear, increase lifespan, improve control accuracy, and provide smoother, quieter motion—especially important in robotics and precision automation.
Yes, depending on winding and mechanical design, but they are primarily optimized for high-torque, low-to-medium-speed applications. We can customize winding profiles for speed-focused applications if needed.
Yes, with appropriate sealing, housing, and cooling design. We offer specialized coatings and material options for applications requiring moisture, dust, or corrosion resistance.
Absolutely. Our team provides support for motor sizing, CAD models, thermal design, controller selection, encoder pairing, and complete integration guidance for robotic and automation platforms.
Frameless torque motors are ideal when you need direct-drive motion with zero backlash, smooth rotation, and high precision—such as in robotic joints, gimbals, medical devices, and semiconductor equipment. Geared motors are better for applications requiring high torque at very low speeds but with less focus on smoothness or precision. Choose frameless torque motors when accuracy, responsiveness, and long-term reliability are top priorities.
Cost is influenced by motor size, custom winding requirements, quantity, magnet grade, insulation class, thermal specifications, and any mechanical customization such as modified stator or rotor geometry. Higher performance materials and tight tolerances also impact cost. We provide tailored quotations based on performance targets and production volume.
