Top 15 China Frameless Motor Manufacturers for Robotics in 2026

Frameless motors are becoming one of the most important motor architectures in robotics. As robot joints become smaller, lighter, and more integrated, traditional housed motors often create limitations in mechanical structure, heat dissipation, torque density, and system layout. For robotic arms, collaborative robots, humanoid robots, exoskeletons, mobile robots, surgical systems, and precision automation platforms, the motor is no longer just a separate component. It is becoming part of the joint itself.

This is where frameless motors, especially frameless torque motors and frameless BLDC motors, become valuable.

A frameless motor usually consists of a stator and rotor without a housing, bearings, shaft, or end cap. The robot designer integrates these motor parts directly into the mechanical joint. This allows the final actuator to be more compact, lighter, and better matched to the structure of the robot. For applications that require high torque density, low backlash, precise motion control, and flexible mechanical integration, frameless motors are often a better choice than conventional motor assemblies.

In 2026, China is becoming an increasingly important sourcing base for frameless motors used in robotics. Public industry reports and company information show that China’s robotics supply chain is developing quickly, especially around core components such as frameless torque motors, harmonic reducers, encoders, and integrated joint modules. China Daily reported in April 2026 that domestic humanoid robots in China have made progress in core hardware including frameless torque motors and harmonic reducers.

For overseas OEM buyers, China-based frameless motor manufacturers can offer several practical advantages: customization flexibility, faster sample iteration, competitive cost, and direct communication with engineering teams. However, choosing the right supplier is not easy. Some companies are very large listed automation groups, while others are smaller specialized motor factories. Some focus on frameless torque motors for robot joints, while others mainly offer BLDC motors, servo systems, or micro motors with limited frameless product coverage.

This article introduces 15 China frameless motor manufacturers and suppliers for robotics in 2026, with a focus on companies that are more suitable for small and medium OEM buyers. The ranking intentionally avoids global giants such as Maxon, Kollmorgen, Moog, Johnson Electric, and other much larger multinational companies, because those companies are not comparable in scale or business model to a China-based medium-sized manufacturer such as Modar Motor.

The goal is not to claim that every company on this list is the “largest” or “best” in China. Instead, this article provides a practical sourcing reference for overseas buyers who need China-based frameless motor suppliers for robotic joints, compact actuators, medical robotics, humanoid robot modules, and customized OEM projects.

Why Frameless Motors Matter in Robotics in 2026

Robotics is moving toward lighter structures, higher torque density, more compact joints, and better motion control. In the past, many robots used conventional servo motors connected to reducers through couplings, housings, shafts, and additional mechanical parts. This structure works, but it can increase weight, size, backlash, and assembly complexity.

A frameless motor changes the integration logic. Instead of installing a complete motor unit into the robot, the designer integrates the stator and rotor directly into the joint. This makes the motor part of the robot’s mechanical structure.

For robot designers, this brings several advantages.

Higher Torque Density

Frameless motors are often selected because they can deliver high torque in a compact package. Since the motor is not limited by a standard housing, the designer can optimize the joint structure around the stator and rotor.

Shorter Axial Length

Robot joints often have very limited axial space. A frameless motor can help reduce the total joint length, especially when combined with a harmonic reducer, encoder, brake, or hollow shaft structure.

Better Mechanical Integration

The motor can be integrated with the robot’s bearing system, reducer, and output structure. This reduces unnecessary mechanical interfaces and can improve stiffness.

Lower Backlash Potential

Backlash is a major concern in robotics. A frameless motor itself does not solve all backlash issues, because the reducer and mechanical structure still matter. However, direct integration can reduce unnecessary couplings and interfaces.

Improved Thermal Design

Because the stator can be mounted directly into the robot housing, heat can be transferred through the mechanical structure. This is useful for robotic joints that operate under frequent acceleration and deceleration.

Better Fit for High-End Robotics

Frameless torque motors are now closely connected with humanoid robots, collaborative robots, exoskeletons, robot dogs, medical robots, and compact automation. For example, MRC Motion’s frameless motor page lists robotics applications including bionic robots, humanoid robots, inspection robots, robot dogs, and robot joint structures.

What Is a Frameless Motor?

A frameless motor is a motor supplied without a traditional outer frame, shaft, bearings, and end caps. It usually includes two main parts:

Stator

The stator is the stationary part of the motor. It contains the winding and is usually fixed into the robot joint housing or another mechanical structure.

Rotor

The rotor is the rotating part. It is usually connected to the output load, reducer, or rotating structure of the robot joint.

In a conventional motor, the stator and rotor are enclosed inside a complete motor housing. In a frameless motor, the robot designer must provide the mechanical structure, bearing support, alignment, and thermal path. This creates more design responsibility, but also gives more freedom.

For robotic joints, this freedom is valuable. Engineers can design a more compact actuator with a hollow shaft, integrated encoder, reducer, brake, or cable-routing path. This is especially useful for humanoid robot arms, collaborative robot joints, exoskeleton joints, camera gimbals, precision rotary axes, and medical motion platforms.

Modar Motor’s own frameless motor page describes its portfolio as covering 25mm to 115mm frame sizes and designed for robotic joints, direct-drive rotary axes, medical motion platforms, and industrial automation equipment. This type of product structure is a strong fit for overseas OEM buyers who need compact and customizable robotic joint motors.

How We Selected These China Frameless Motor Manufacturers

This article uses a practical B2B sourcing perspective. The ranking is not based only on revenue, stock market value, or brand popularity. Instead, it considers whether a company is relevant for overseas buyers sourcing frameless motors for robotics.

The selection factors include:

3. Robotics Application Fit

The company should be relevant to robotic arms, humanoid robots, collaborative robots, exoskeletons, compact automation, medical robotics, or precision motion.

4. OEM and Customization Potential

For robotics, standard catalog motors are often not enough. Suppliers with OEM, ODM, or customization capability are more useful for B2B buyers.

5. Reasonable Scale Match

This article avoids companies whose scale is clearly far beyond Modar Motor’s position. Some larger domestic automation brands may be mentioned only when they are relevant to market context, but the ranking prioritizes specialized and medium-scale suppliers where possible.

6. Public Information Availability

The ranking is based on publicly available website pages, product pages, supplier listings, and company descriptions. Buyers should verify the latest specifications, production capacity, certifications, and project fit directly with each supplier.

How to Choose a China Frameless Motor Manufacturer for Robotics

Choosing a frameless motor manufacturer is more complex than buying a standard motor. The motor must match the mechanical structure, control system, reducer, encoder, thermal design, and production plan.

[Insert Image 2 Here: China Frameless Motor Supplier Checklist]

Confirm the Robot Joint Structure

Before contacting suppliers, define the joint structure clearly. Important questions include:

• Is the motor used in a shoulder, elbow, wrist, finger, wheel, or rotary platform?

• Will the design use a harmonic reducer, planetary reducer, cycloidal reducer, or direct drive?

• Is a hollow shaft required for cable routing?

• Is the encoder installed inside the joint?

• Is the motor stator fixed to an aluminum housing or another heat-dissipation structure?

A frameless motor supplier cannot recommend the right model without understanding the full joint design.

Define Torque and Speed Requirements

For robotic joints, torque and speed requirements should include:

• Rated torque

• Peak torque

• Rated speed

• Maximum speed

• Continuous current

• Peak current

• Duty cycle

• Required acceleration

• Holding torque or braking requirements

Many projects fail because buyers only provide voltage and diameter. That is not enough for a frameless motor selection.

Check Thermal Performance

Frameless motors depend heavily on how they are installed. The same stator and rotor may perform differently depending on housing material, cooling path, duty cycle, and ambient temperature.

Ask suppliers for:

• Continuous torque data

• Peak torque data

• Temperature rise data

• Thermal resistance

• Recommended installation method

• Maximum winding temperature

Ask About Cogging Torque and Torque Ripple

Robotics requires smooth motion. Low cogging torque and low torque ripple are important for precision control, especially at low speed.

Ask the supplier whether they can provide:

• Cogging torque data

• Torque ripple data

• Back EMF waveform

• Magnetic design information

• Sample test reports

Confirm Encoder and Controller Matching

A frameless motor is only one part of the joint. The encoder and controller must match the motor.

Important questions include:

• Is Hall sensor feedback required?

• Is a magnetic encoder required?

• Is an optical encoder required?

• What controller will be used?

• Does the motor support FOC control?

• Is the motor designed for low-voltage or high-voltage drive?

Evaluate Sample Support

A supplier should be able to support sample development, not only quote a price.

A good sample process should include:

1. Requirement review

2. Model recommendation

3. Drawing confirmation

4. Sample production

5. Testing

6. Feedback and revision

7. Pilot batch

8. Mass production

Check Production Consistency

Robotic joint motors need batch consistency. Small variations in winding, magnet assembly, air gap, or rotor balance can affect final robot performance.

Before mass production, buyers should ask about:

• Incoming material inspection

• Winding process control

• Magnet assembly method

• Dynamic balance

• Electrical testing

• Insulation testing

• Torque testing

• Final inspection reports

Why China-Based Frameless Motor Manufacturers Are Attractive for Overseas OEM Buyers

China-based manufacturers are becoming attractive for overseas robotics OEM buyers because the robotics supply chain is developing quickly in China. In addition to motors, China has strong supply networks for reducers, encoders, PCBs, controllers, bearings, magnets, shafts, cables, and precision machining.

Faster Customization

Many China-based manufacturers are willing to customize voltage, winding, stator size, rotor size, cable exit, connector type, and mounting details for OEM projects.

Better Fit for Small and Medium OEM Buyers

Large international motor brands often focus on standardized products or large customers. Small and medium OEM buyers may need more flexible engineering communication.

Competitive Cost

For the same project, China suppliers may offer better cost flexibility, especially when the buyer needs customization or medium-volume production.

Shorter Development Iteration

Robotics projects often require several design iterations. A flexible manufacturer can help adjust drawings, samples, and performance details more quickly.

Integrated Supply Chain

The motor is only one part of the actuator. China’s integrated supply chain can help buyers source related parts such as reducers, encoders, controllers, and mechanical components.

Common Mistakes When Sourcing Frameless Motors for Robotics

Mistake 1: Comparing Only Price

A cheaper frameless motor may become more expensive if it causes overheating, vibration, noise, unstable control, or batch variation.

Mistake 2: Ignoring Installation Conditions

Frameless motor performance depends on how the motor is installed. Housing material, air gap, alignment, bearing support, and heat dissipation all matter.

Mistake 3: Choosing by Diameter Only

A 70mm frameless motor from one supplier may perform very differently from a 70mm motor from another supplier. Torque, stack length, magnet design, winding, and thermal design must be compared.

Mistake 4: Not Testing the Full Joint

Testing the motor alone is not enough. The full actuator should be tested with reducer, encoder, controller, housing, load, and actual motion profile.

Mistake 5: Not Confirming Batch Control

A good sample does not guarantee stable mass production. Buyers should request pilot batches and compare consistency.

Mistake 6: Confusing Frameless Motor and Complete Actuator

A frameless motor is not a complete joint module. It usually does not include bearing, shaft, housing, encoder, reducer, or controller unless the supplier provides an integrated solution.
