What is a frameless torque motor and how does it work?

A frameless torque motor is a direct drive brushless motor consisting of separate rotor and stator components without a traditional motor housing. The motor can be directly integrated into the customer's mechanical structure, providing high torque density, high precision, and smooth rotation performance for robotic and automation applications.

What are the main applications of frameless torque motors?

Frameless torque motors are widely used in robotics, collaborative robots (cobots), robotic joints, AGV/AMR systems, precision rotary tables, CNC equipment, semiconductor equipment, and industrial automation machines where compact size and high torque output are required.

What is the advantage of using a frameless torque motor instead of a traditional motor with gearbox?

A frameless torque motor provides direct drive operation, reducing mechanical transmission components and eliminating backlash from gear systems. This helps achieve higher positioning accuracy, faster dynamic response, lower noise, and improved system reliability.

Can DXTL customize frameless torque motors according to customer requirements?

Yes. DXTL supports OEM and ODM customization, including motor diameter, rated voltage, torque, speed, winding design, encoder feedback, mounting dimensions, and mechanical interfaces to meet different robotic and industrial automation requirements.

How do I select the right frameless torque motor for my application?

The selection depends on several factors, including required torque, speed, available installation space, voltage, duty cycle, control system, and feedback requirements. DXTL can provide technical support and recommend a suitable frameless torque motor based on your application parameters.
