As high-speed developments in humanoid robots, precision medical devices, smart photoelectric equipment, and high-end industrial automation continue to surge, the demand for miniaturized, lightweight, high-precision, and ultra-stable power transmission systems is escalating. Traditional motor-gearbox combinations suffer from severe mechanical backlash, response lag, bulky structures, high wear, and high maintenance costs—falling short of modern precision engineering standards.
XH Motor Frameless Torque Motors (FT Series) adopt a split rotor-and-stator design without an outer housing. By eliminating redundant structures like casings, bearings, and end caps, they can be directly embedded into the mechanical transmission structure. With their unique frameless architecture, exceptional low-speed high-torque performance, and ultra-high integration, they have become the mainstream direct-drive solution for robotic joint modules and precision motion systems.
I. Core Advantages of XH Frameless Torque Motors
Compared to traditional integrated motors and geared transmission modules, XH frameless torque motors deliver comprehensive performance advantages in structural design, transmission accuracy, dynamic response, lifespan, and mass production adaptability.
1. Embedded Integration Design for Extreme Lightweighting
- Space-Saving: The split structure with no external frame supports nested, embedded installation directly inside robotic joints, precision rotary tables, and photoelectric gimbals.
- Compact Footprint: Significantly reduces overall equipment volume and weight under identical power parameters, perfectly matching space-sensitive applications such as humanoid robot dexterous hands, micro-photoelectric devices, and portable medical instruments.
2. Direct-Drive Zero-Backlash for Ultimate Precision
- Zero Mechanical Backlash: Eliminates all intermediate transmission components to completely eradicate gear backlash, transmission lag, and mechanical vibration.
- Smooth Control: Optimized magnetic circuit design minimizes cogging torque for ultra-smooth low-speed operation, precise angle positioning, and minimal repetitive positioning error.
3. Wide-Range Torque Coverage & Strong Power Adaptability
- High-Torque Density: Features a ring-shaped hollow, high-torque electromagnetic structure providing low-speed constant torque and high starting thrust without high-speed gear reduction.
- Versatile Range: Covers micro-precision torque to industrial heavy-load ranges, satisfying micro-drives, standard automation, and heavy-duty continuous operations alike.
4. Low Loss, Long-Term Maintenance-Free Reliability
- High Durability: Minimalist direct-drive structure drastically cuts mechanical wear points. Combined with premium winding and magnetic steel materials, it ensures low electromagnetic loss, controllable temperature rise, and long operational life without regular maintenance.
