Read MoreThe Dunkermotoren ST11 Series Linear Motor is a compact and precise solution, delivering exceptional linear motion performance for high-speed, high-accuracy applications. With peak forces reaching 91.9 N and continuous stall forces up to 19.28 N, the ST11 Series is ideal for automation, medical devices, and robotics.
Key features include an integrated high-resolution sin/cos feedback sensor for repeatability of ±6 microns and absolute accuracy of ±350 microns. Available in actuator (STA) and component (STB) versions, the ST11 Series offers flexibility to meet diverse application requirements. The actuator version includes high-performance polymer bearings, while the component version is optimized for compact installations. The motor’s robust IP67-rated design ensures durability and resistance to demanding environments.
The ST11 Series supports speeds of up to 5.6 m/s (STA version) and accelerations as high as 422 m/s², making it a high-dynamic solution for precision applications. With low maintenance and integrated feedback for enhanced control, the ST11 Series is a versatile choice for industries requiring reliable linear motion systems.
For advanced linear motion performance and adaptability, the Dunkermotoren ST11 Series Linear Motor delivers precision, speed, and durability.
