LS4 Motor


Nanomotion’s family of LS Series motors are available in configurations with 2, 4 and 8 elements. The LS Series provides unmatched resolution for repetitive step and settle applications with zero servo dither when in position. The LS Series is capable of reach step sizes in the few nanometers range with the maximum speed of 50mm/sec.
The LS2 motor offers 2N force, the LS4 motor offers 4N and the LS8 offers 8N force.
