PMDC Right Angle Gearmotor
Model RA40 (120 to 240W)
Worm gear reducers have a distinct advantage of having very low audible noise. The
right angle output configuration results in a compact, low profile mounting.
Extraordinary efficiency, relative to standard worm gear reducers, is achieved with the
use of a custom-designed. High-strength bronze worm wheel with optimized tooth profile
for high torque transmission. Die cast Zinc alloy housing.
