FMK Series Frameless Torque Motor
Designed for Humanoid / Collaborative / Quadruped Robotic Joints
FMK Frameless Torque Motor
The FMK medium & large frameless torque motor is designed for robotic joints and other high-precision integrated equipment. Compared with the FMC series, it provides lower temperature rise, a larger hollow bore, higher continuous torque, faster dynamic response and improved operational stability.
Its enlarged hollow bore supports flexible cable routing, while the compact design delivers high continuous power with high torque density in limited installation space. These characteristics make the FMK series suitable for humanoid, collaborative and quadruped robot joint motor applications, as well as other precision motion systems.
