Direct-Drive Motors for Outstanding Control

To maximize positioning and velocity performance,

AMG-LP gimbal mounts utilize Aerotech’s high torque

S-series brushless, slotless servomotors. These motors

have all of the advantages of a brushless direct-drive

motor — no brushes to wear, no gear trains to maintain,

high acceleration, and high speeds. Since it is a slotless,

ironless design, there is zero cogging, meaning there is

absolutely no torque ripple. This results in smoother motion

throughout travel and more precise positioning. These

motors are available in different winding configurations to

work with high- or low-voltage power supplies.

Notes:

1. ±24 µrad calibrated (HALAR); ±192 µrad uncalibrated.

2. Repeatability and accuracy are dependent on encoder resolution. To achieve the listed specifications, encoder resolution must be 0.36 arc sec or less.

3. Maximum speed based on stage capability; maximum application velocity may be limited by system data rate and system resolution.

4. Unloaded inertia.
