Polygon Motor Assembly Model M-660-010-LVWOB
The low cost model M-660-010-LVWOB is designed and manufactured specifically for high volume precision laser scanning applications. Available "off the shelf" with #8-32 UNC thread or M4 x .07 metric mounting threads. Precision high speed instrument bearings and a dynamically balanced polygon rotor assembly assure a trouble free service life in excess of 10,000 hours. A two piece closed slot stator eliminates eddy current drag on the rotor, providing cool running at high speeds. Facet to rotational axis dynamic accuracy is better than +/-30 arc seconds at all speeds.
