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.
The Nanomotion LS Series offers unique servo performance at low velocities, with exceptional constant velocity stability. The LS Series is well suited to high step/repeat applications such as auto focus, where small steps are required over a long period of time.
The LS2 motor offers 2N force, the LS4 motor offers 4N and the LS8 offers 8N of driving force.

Nanomotion supplies ceramic drive strips, rings, and CCS Ceramic Coated Steel for all our motor types. Standard strips, rings and disks are available in a wide variety of sizes and shapes. Nanomotion can also provide custom drive strips/rings for different application requirements. The mating drive surface is critical to the motor’s performance. All specifications are based on using Nanomotion’s drive surfaces. Most of Nanomotion’s standard drive strips are provided with vacuum compatible, double sided tape for easy mounting. The motor user manual defines the proper mounting procedure.
Standard Ceramic Strips:
CCS (Ceramic Coated Steel)
CR (Ceramic Rings)
Available length:
