Introduction to Frameless Torque Motors
Frameless torque motors are a type of direct – drive motor with a unique design. Unlike traditional motors with an integrated housing, bearings, and shaft, frameless torque motors consist of only a rotor and a stator. This design offers several advantages. Firstly, it allows for more flexible integration into various machine designs, enabling engineers to create more compact and efficient systems. Secondly, frameless torque motors can provide high torque at low speeds, making them ideal for applications where precise motion control is required, such as robotics, machine tools, and aerospace equipment. They also eliminate the need for intermediate transmission components like gears, which reduces mechanical losses, noise, and maintenance requirements. Frameless Torque Motor
