Frameless Torque Motors

Lin Engineering designs and manufactures frameless torque motors that integrate seamlessly into a wide range of applications, providing engineers with unmatched flexibility, precision, and reliability. The frameless design allows the rotor and stator to be incorporated directly into the system, reducing weight and optimizing space. With high power density and customizable specifications, Lin Engineering’s frameless torque motors ensure optimal performance and durability, empowering engineers to achieve greater efficiency and innovation in the most demanding applications.

In the world of motion, precision, and reliability, our motors form the Core—the backbone of movement across diverse applications. The name "Core" reflects our belief that, whether driving a gimbal, supporting cobots, or powering demanding, high-performance systems, each motor series is an essential element that enhances the function and reliability of any system it serves.

FlexCore, PowerCore, and XtremeCore are engineered to be integral to your application, providing the foundation upon which efficiency, high performance and innovation are built.
