Five Key Evaluation Criteria When Purchasing Frameless Motors

Brand reputation alone should not determine supplier selection. Based on extensive international purchasing experience, suppliers should be evaluated from the following five perspectives.

Product Capability: Standard Products vs Customization

Confirm whether the supplier can meet your application requirements, including:

• Outer diameter

• Motor thickness

• Hollow shaft diameter

• Continuous torque

• Peak torque

• Rotor inertia

For prototype development, standard models may be sufficient.

For mass production, customers should evaluate customization capabilities including:

• Winding design

• Magnet configuration

• Sensor options

Important Note:
For robotic joint applications, continuous torque performance is more important than peak torque.

Many suppliers show impressive peak torque values in catalogs but cannot maintain stable continuous output.

Engineering Support Capability

Frameless motors are not finished products. They consist of separate stator and rotor components, requiring customers to complete:

• Mechanical integration

• Thermal management design

• Encoder matching

• Servo drive tuning

A professional supplier should provide:

• Torque-speed curves

• Temperature sensor specifications

• Air gap requirements

• Rotor/stator assembly instructions

• Electrical parameter files

For overseas customers, English technical documents and assembly manuals are especially important.

Delivery Time and Supply Chain Stability

For overseas OEM projects:

• Prototype stage requires small-batch supply

• Mass production requires stable capacity

Some international premium brands may have lead times of 12–24 weeks.

High-quality Chinese manufacturers can often provide prototypes within several weeks and support stable mass production.

Purchasing decisions should match the supplier's delivery capability with the project timeline.

Export Capability and Certifications

Export equipment requires suppliers capable of providing:

• CE-related documents

• Insulation grade information

• Temperature resistance data

• Wide voltage customization

• High/low temperature adaptation

Without export experience, motors that perform well domestically may fail under overseas conditions such as:

• High humidity

• Extreme temperatures

• Different power systems

Cost and Mass Production Capability

European and American brands offer excellent performance but higher prices.

For large-scale humanoid robot production, manufacturers must balance:

• Performance

• Cost

• Delivery

• After-sales risks

The cheapest supplier is not always the best choice.

How to Select the Right Frameless Motor Manufacturer for Different Applications

Humanoid Robots / Collaborative Robot Joints

Priority should be given to suppliers with:

• Large hollow-shaft motor experience

• Strong continuous torque performance

• Proper inertia matching

• Customization capability

• Prototype-to-production support

Medical Precision Equipment

Focus on:

• Insulation grade

• Clean environment compatibility

• Certifications

• English technical documentation

Semiconductor Equipment / Precision Rotary Tables

Important factors:

• Continuous torque stability

• Direct-drive technology experience

Aerospace and Defense Equipment

Choose manufacturers capable of:

• Vacuum customization

• Extreme temperature operation

• Special environmental testing

Prototype Development

Select suppliers with:

• Complete standard product range

• Short delivery cycles

• Small-batch production support

Common Purchasing Mistakes When Selecting Frameless Motors

Mistake 1: Assuming Famous Brands Always Fit the Project

International brands have strong technical capabilities, but their products may not perfectly match every application.

Some suppliers specialize in industrial standard models, while customized large hollow-shaft robot motors may require long lead times and high costs.

Mistake 2: Comparing Only Catalog Parameters

The success of frameless motor integration depends heavily on system engineering.

If suppliers only provide hardware without:

• Assembly instructions

• Electrical parameters

• Integration support

customers may face problems such as:

• Rotor-stator friction

• Overheating

• Control instability

Mistake 3: Ignoring Export Environment Requirements

Motors tested in domestic environments may fail in:

• High temperature regions

• Cold climates

• High humidity environments

Potential issues include:

• Magnet demagnetization

• Insulation failure

Always confirm the target export environment with suppliers.

Mistake 4: Using Prototype Suppliers as Mass Production Suppliers

Prototype suppliers focus on rapid development.

Mass production requires:

• Production capacity

• Consistency

• Yield control

Not every prototype supplier can support large-scale production.

Frequently Asked Questions

Q1: Should prototype and mass production use the same frameless motor supplier?

A: Ideally yes.

Different suppliers may have different winding designs and magnet technologies. Switching suppliers later requires repeating:

• Load testing

• Temperature testing

• Inertia verification

which increases development costs.

Q2: What technical documents should overseas buyers request?

A: Recommended documents include:

• Motor datasheet

• Torque-speed curve

• Rotor/stator assembly requirements

• Air gap and concentricity requirements

• Temperature sensor specifications

• Resistance and inductance data

• English assembly manuals

• Export certification documents

Q3: What are the main differences between Chinese and European/American frameless motors?

A:For extreme applications such as aerospace vacuum environments, overseas brands still have deeper experience.

However, for mainstream robotics and medical automation applications, leading Chinese manufacturers can already achieve comparable performance while offering advantages in:

• Customization flexibility

• Delivery speed

• Cost efficiency

• Export support

Q4: Can HOLRY provide both prototypes and mass production?

A:Yes.

HOLRY supports:

• Prototype development

• Small-batch trial production

• Large-scale OEM manufacturing

The company provides standard frameless motor series and customized solutions including:
