DC linear motor LM Series

iron-corecoreless48 V

Product overview
INFRANOR linear motors are direct‑drive actuators engineered for very high dynamics and precision. Available in coreless (U‑shaped) and iron‑core variants, they deliver fast accelerations, high peak speeds and a wide thrust range suited to ultra‑precision machining, semiconductor handling and high‑speed industrial automation.
