The LS motors are ideal for low speeds of less than 1 mm/sec and down to 10 microns/sec, and can maintain very low position error at these velocities. The Low Speed (LS) series of motors consist of three motors, LS-2, LS-4 and LS-8, which were designed specifically for high resolution and low speed applications. These motors were designed for maximum no-load velocity of 20 mm/sec and stall forces of approximately 25% of the standard Nanomotion HR series motors.
The new features offered in the LS series of motors are as follows:
- New friction pair optimized for requirements of high resolution and low speed.
- Reduced starting voltage (dead band).
- Dual phase operation of the finger tips. Each pair of finger tips operates at 180º out of phase.
Each motor within the LS series has its own special AB-1 driver box, with dedicated LC circuits that differs from the LC circuits used with the standard Nanomotion HR series motors. The dedicated AB1 Driver Box limits the output to the motor to a maximum command of 3.5V.Brief specifications for the LS series motors are presented in the table below:
| Specification | LS-2 | LS-4 | LS-8 |
| Maximum allowed velocity [mm/sec | 20 | 20 | 20 |
| Stall force [N} | 2 | 4 | 8 |
| Static Holding force (reference value) [N] | 3.5 | 7 | 14 |
| Starting command voltage [V] (reference value) | 1 | 1 | 1 |
| Maximum voltage [V-RMS} | 180 | 180 | 180 |
