Introduction (Covering Core User Needs & Pain Points):
Robotics engineers, aerospace actuation designers, and precision motion control specialists face a critical torque delivery challenge: achieving high torque density (Nm/kg), zero backlash, low cogging, and high dynamic response without the bulk, complexity, and compliance of traditional gearboxes (harmonic drives, planetary gears). Conventional framed motors with external housings, bearings, and couplings add weight, inertia, and mechanical play, reducing positioning accuracy and bandwidth for direct-drive applications. The Frameless Permanent Magnet Torque Motor – a direct-drive torque motor utilizing a toroidal coil and radially distributed permanent magnet structure, eliminating the traditional frame (housing, bearings, shaft), integrated directly into the user’s mechanical system – directly addresses these gaps by providing: (1) high torque density (5-20 Nm/kg), (2) zero transmission backlash (direct drive), (3) extremely low moment of inertia (rotor only), (4) high dynamic response (acceleration >10,000 rad/s²), (5) low cogging torque (<1% of rated), (6) large hollow shaft (for cables, optics, fluids). However, procurement managers face complex decisions: rotor type (inner vs. outer), diameter (50-500mm), torque rating (1-1,000 Nm), peak speed (100-5,000 rpm), and integration (customer-supplied bearings, housing, encoder). This industry research report by QYResearch provides a data-driven roadmap for humanoid robot developers (Tesla Optimus, Boston Dynamics Atlas, Figure 01, 1X Technologies), semiconductor equipment OEMs, and medical device manufacturers. Global Leading Market Research Publisher QYResearch announces the release of its latest report “Frameless Permanent Magnet 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 Frameless Permanent Magnet Torque Motor market, including market size, share, demand, industry development status, and forecasts for the next few years.
Market Size & Product Definition:
The global market for Frameless Permanent Magnet Torque Motor was estimated to be worth US946millionin2025andisprojectedtoreachUS946millionin2025andisprojectedtoreachUS 4,511 million by 2032, growing at a CAGR of 25.0% from 2026 to 2032. In 2025, the global average price was US$ 350 per unit, with annual sales of approximately 2.7 million units. (Note: Price estimated based on industry data; original report had placeholder.)
A frameless permanent magnet torque motor consists of a stator (toroidal winding) and a rotor (permanent magnets – NdFeB, SmCo) with no housing, bearings, or shaft. The user’s mechanical structure (robot joint housing, gimbal, direct-drive rotary table) provides support and thermal management. Key advantages over framed motors: 30-50% smaller volume, 40-60% lower inertia, higher system stiffness (no coupling).

Section 1: Technology Segmentation – Inner vs. Outer Rotor
By Type (2025 Market Share – QYResearch data):
- Inner Rotor Type (Magnets on inner surface of rotor, stator outside): 60% share (largest; lower inertia, higher speed (5,000+ rpm), suitable for collaborative robots, semiconductor wafer stages, medical scanners)
- Outer Rotor Type (Magnets on outer surface of rotor, stator inside): 40% share (fastest-growing at 30% CAGR; higher torque density (20-40% more torque for same diameter), larger hollow shaft, suitable for humanoid robot joints (hip, knee, shoulder) and direct-drive rotary tables)
By Application (2025 Market Share):
- Collaborative Robots (cobots) (Universal Robots, Doosan, Techman, Rethink, Franka Emika): 35% share (largest; frameless motors for joint modules (6-7 axes), low voltage (48V) for safety)
- Humanoid Robots (Tesla Optimus, Boston Dynamics Atlas, Figure 01, 1X Neo, Xiaomi CyberOne, Honda Asimo, Agility Digit): 25% share (fastest-growing at 50% CAGR; 30-50 motors per robot (finger, wrist, elbow, shoulder, hip, knee, ankle); requires high torque density, low cogging, hollow shaft for wiring, and low voltage (48-96V))
- Medical Equipment (CT scanner gantry (direct-drive), MRI patient table, surgical robots (da Vinci), prosthetic joints, exoskeletons, dental milling machines, robotic rehabilitation devices): 20% share (requires low cogging (<0.5%), smooth motion, and reliability)
- Others (Semiconductor wafer handling (direct-drive rotary stages, theta stages), aerospace (satellite solar array drives, gimbal actuators, antenna positioning), defense (radar, directed energy weapons), machine tools (direct-drive rotary tables), packaging (indexing drives), printing (CMYK registration), energy (wind turbine yaw drives), electric vehicles (wheel hub motors)): 20% share

Section 3: Exclusive Industry Observation – Humanoid Robot Market Catalyst
A 2025-2026 trend: Humanoid robots (Tesla Optimus, Figure 01, 1X Neo) are entering pilot production (10,000-100,000 units/year). Each humanoid requires 30-50 frameless torque motors (fingers, wrists, elbows, shoulders, hips, knees, ankles). Specifications: 48-96V DC, torque density >10 Nm/kg, diameter 30-150mm, hollow shaft (for wiring), low cogging (<1%), integrated encoder (hall, resolver, optical). TQ Robodrive (ILM series) and Kollmorgen (TBM2) are qualified for Optimus.
A典型案例 (case study): Tesla Optimus Gen 2 (2025) uses 28 frameless torque motors (Kollmorgen TBM2, Chinese suppliers for cost reduction). Key joints: hip (150 Nm peak, 80mm OD, hollow shaft), elbow (30 Nm, 50mm OD), finger (0.5 Nm, 15mm OD). Motor cost per robot: US2,800(28×US2,800(28×US 100). At 1 million robots/year (2030), the humanoid motor market reaches US$ 2.8 billion (50% of total frameless motor market).
Section 4: Technical Challenges and Design Barriers
- Low voltage, high power: Humanoid robots operate at 48-96V (safety). Achieving high torque (100 Nm) at low voltage requires high current (200-500A), challenging for PCB (printed circuit board) bus bars and connectors.
- Thermal management: Frameless motors rely on user’s housing for cooling. Humanoid joints (enclosed, no fan) require low copper loss design (high fill factor, low resistance).
- Magnetic design: Cogging torque reduction (<1%) via skewing, fractional slot concentrated winding (FSCW), or segmented magnets.
Section 5: Market Forecast
By 2032, Asia-Pacific will be largest (45% share – China (Tesla Optimus supply chain, Ubtech, Xiaomi, Fourier Intelligence), Japan, South Korea), North America 25%, Europe 20%, RoW 10%. Inner rotor will maintain 55-60% share (for cobots and medical). Humanoid robots will become largest application (40% share) by 2030, surpassing cobots. Market growth drivers: humanoid robot commercialization (Tesla, Figure, 1X, Boston Dynamics, Xiaomi, Honda, Hyundai), collaborative robot expansion (Universal Robots, Doosan, Techman, Fanuc, Yaskawa, ABB, Kuka), and semiconductor equipment growth (wafer handling stages). Key success factors: low voltage (48V, 96V), high torque density (>15 Nm/kg), low cogging (<0.5%), hollow shaft (>50% of OD), encoder integration (Hall, resolver, optical, magnetic), and cost reduction (target US$ 50-150 per motor).
