Modern automation demands motors that are smaller, lighter, and more efficient than ever before. Traditional motors with bulky housings often can't meet these strict requirements.
Frameless motors solve this problem by eliminating the outer frame entirely. They offer direct integration into machines. This creates compact, powerful solutions for robotics, aerospace, and medical devices.
In this guide, you'll learn what frameless motors are and how they work. We'll explore their key advantages over traditional motors. You'll discover when to choose frameless technology for your applications.
A frameless motor is exactly what it sounds like - a motor without a frame or housing. It consists of just two essential parts: the rotor and stator.
The rotor contains permanent magnets arranged in a specific pattern. The stator features copper coils wound in a circular design. These components work together to create rotational motion.
Traditional motors come with many extra parts. They have housings, bearings, shafts, and cable connectors. Frameless motors eliminate all these components. You get only the parts that actually produce motion.
Think of it like removing the shell from a complete motor. You're left with the core components that do the real work. This stripped-down design offers incredible flexibility for custom applications.
The differences between frameless and traditional motors go far beyond just the housing.
Structural Differences
Traditional motors come as complete units ready to bolt into place. They include everything needed for operation. Frameless motors require you to provide the housing, bearings, and mounting system.
Integration Approaches
Traditional motors mount externally to your machine. They connect through couplings or belt drives. Frameless motors integrate directly into your machine's structure. The rotor can mount directly on your application's shaft.
Key Comparison Points

Cost Implications
Traditional motors cost less upfront. They're ready to use immediately. Frameless motors require additional engineering and custom components. However, they often provide better value in high-volume production.
Frameless motors come in several configurations. Each type serves different application needs.
Frameless BLDC Motors
Brushless Direct Current motors are the most common frameless type. They use electronic switching instead of physical brushes. This eliminates wear points and reduces maintenance needs.
BLDC frameless motors offer excellent efficiency. They provide precise speed and position control. They're ideal for applications requiring high performance and reliability.
Frameless Torque Motors
These motors prioritize torque over speed. They feature short axial length compared to their diameter. This design maximizes torque density.
Torque motors excel in direct-drive applications. They eliminate the need for gearboxes in many cases. This reduces complexity and improves precision.
Kit Motors and Rotor/Stator Kits
Some manufacturers offer frameless motors as complete kits. These include the rotor, stator, and sometimes feedback sensors. You still need to provide housing and bearings.
Kit motors simplify the integration process. They ensure compatibility between components. This reduces engineering time and potential issues.
Servo vs Torque Motor Configurations
Servo configurations feature longer axial length. They're optimized for speed and dynamic response. They work well with feedback systems for precise positioning.
Torque configurations prioritize maximum torque output. They're shorter and wider than servo types. They're perfect for applications needing high torque at lower speeds.
The choice depends on your specific requirements. Consider torque needs, speed requirements, and space constraints when selecting.
Frameless motors work through electromagnetic principles. They create motion by generating magnetic fields between two key components.
The stator contains copper wire coils arranged in a circular pattern. When electricity flows through these coils, it creates a magnetic field. This field rotates around the stator's center.
The rotor holds permanent magnets in a complementary arrangement. These magnets interact with the stator's rotating magnetic field. This interaction causes the rotor to spin continuously.
Power enters the system through the stator windings. The magnetic field interaction converts electrical energy into mechanical motion. This process happens instantly when you apply current.
Feedback devices monitor the rotor's position constantly. They send position data to the control system. This creates a closed-loop system for precise motion control.
Frameless motors need precise alignment during installation. The air gap between rotor and stator must be exact. Even small misalignments can cause vibration or reduced performance.
Electrical connections require careful planning. You must route power cables to the stator windings safely. Heat-resistant wiring is often necessary for high-power applications.
The feedback device needs proper mounting and alignment. Encoders or resolvers must track rotor position accurately. Poor feedback alignment leads to control problems.
You'll need to provide your own housing and bearings. The housing must support both stator and rotor securely. Bearing selection affects motor life and performance significantly.
Key Integration Components:
