FAQ – Frameless Torque Motors
What is a frameless motor?
A frameless motor is a direct-drive motor consisting of a stator and rotor without housing, bearings or shaft. Frameless motors provide higher torque density, compact integration and zero backlash motion for precision automation systems.
Frameless torque motors are widely used in robotics, semiconductor equipment, CNC rotary tables and medical imaging devices.
What are frameless torque motors?
Frameless torque motors are a type of electric motor with a toroid-shaped design that can directly drive an application without additional mechanical components such as belts, pulleys, or worm gears. Because they eliminate mechanical transmission elements, they are also known as direct drive motors.
What are the advantages of frameless torque motors?
Key advantages include:
- Compact and lightweight design
- High torque at low speeds
- High positioning accuracy
- Reduced mechanical complexity
- Easy integration into custom systems
- Lower overall system costs
Where are frameless torque motors commonly used?
Frameless torque motors are widely used in applications that require high precision, reliability, and smooth motion, including:
- Food and packaging machinery (conveyor belt propulsion)
- Robotics and semiconductor equipment
- Industrial and agricultural HVLS fans
- Machine tools and automated systems
- Medical equipment such as imaging systems
- Aerospace systems including satellites, gyroscopes, and inertial navigation systems
