Hiwin Ironless Motors - LMC-EFC series

The HIWIN LMC-EFC series: LMC-EFC = Height of stator 50.8mm, Peak: 150N - 600N / Continuous: 38N - 150N

Linear Ironless Motors - LMC-EFC series

The HIWIN LMC coreless U-shaped linear motor has no cogging, an excellent low velocity ripple and excellent dynamic characteristics. With no attraction between forcers and stators and very low-profille structure, the motor can be applied to the installation platform without deformation and has a light load demand for continuous movement curve. For exemple: high-speed, light-load automation equipment, dust-free environment automation equipment, flat panel equipment, optical detection quipment, scanning electron microscope equipment, semiconductor equipment.
