Industry Deep-Dive: Inner Rotor vs. Outer Rotor Frameless Torque Motors for High-Precision Positioning and Smooth Torque Output
Global Leading Market Research Publisher QYResearch announces the release of its latest report “Toroid Shaped Frameless Torque Motor – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. Based on current situation and impact historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global Toroid Shaped Frameless Torque Motor market, including market size, share, demand, industry development status, and forecasts for the next few years.
Core User Pain Point & Solution Direction: Precision equipment designers face a critical motion control challenge: traditional servo motors with gearboxes suffer from backlash (position error), limited dynamic response, and high moment of inertia. Toroid Shaped Frameless Torque Motor (TFM) solves this through direct-drive technology. This motor utilizes a toroidal coil and radially distributed permanent magnet structure. Eliminating the traditional frame structure (base and bearing supports), it integrates directly into the user’s mechanical system, offering high torque density, zero transmission backlash, extremely low moment of inertia, and high dynamic response. Its toroidal structure ensures a large hollow channel while also achieving greater torque uniformity and low cogging. TFMs are ideally suited for satellite attitude control systems, aerospace servos, semiconductor wafer handling, medical imaging equipment, and advanced robotic joints. In 2025, global TFM production reached approximately 2 million units.
Global Market Size & Growth Trajectory
The global market for Toroid Shaped Frameless Torque Motor was estimated to be worth US795millionin2025andisprojectedtoreachUS795millionin2025andisprojectedtoreachUS 1,569 million, growing at a CAGR of 10.2% from 2026 to 2032. With increasing demand for high-performance direct-drive technology in precision equipment, aerospace exploration, and the new energy industry, TFMs are becoming a key growth area in the drive sector. The demand driver is shifting entirely from traditional industrial automation to humanoid robot joint applications.
Market Share & Competitive Landscape
Leading players include Kollmorgen, Moog, Nidec, Kinco Automation, Tecnotion, Aerotech, Wittenstein, Maxon Motor, Allied Motion, and Shenzhen Mosrac Motor. The top five players account for approximately 38% of global market share. Chinese manufacturers (Kinco, Haozhi, Weijing, Leadshine) are gaining share rapidly in robotics applications.

Recent Breakthrough – Humanoid Robot Joint Integration
During its 2025 earnings call, Weiguang Holdings disclosed that robotic joint modules developed by its subsidiary have entered small-batch delivery, integrating TFM with encoders. Jiangsu Leili confirmed on its investor platform that its frameless torque motors integrated with planetary gearboxes and encoders have achieved small-batch shipments. Kinco Automation disclosed that sales of frameless torque motors increased significantly, driven by industrial robots, humanoid robots, and collaborative robots.
Policy Support
The Science, Technology and Economy Commission of Shanghai Pudong New Area issued a special application notice supporting enterprises undertaking industrialization of frameless torque motors for humanoid robots, providing financial support based on first-batch sales contract value. This local incentive policy guides enterprises to push TFMs from prototype trial toward scaled supply.
Exclusive Observation: Profit Model Upgrading
The industry is transforming in three ways: (1) demand driver shifting from industrial automation to humanoid robot joints; (2) profit model upgrading from single motor sales to system solutions (joint modules integrating encoders and reducers); (3) company revenue growth depends on industrialization of magnetic circuit optimization, process consistency control, and module integration capabilities.
