PMDC Right Angle Gearmotors

Merkle-Korff PMDC Right Angle Gearmotors feature a high efficiency worm gear design that allows you to downsize the motor and draw less current for a given load — creating a more energy efficient solution with a smaller footprint. These Merkle-Korff gearmotors have the distinct advantage of generating very low audible noise. The right angle output configuration results in a compact, low-profile mounting.

Extraordinary efficiency — relative to standard worm gearboxes — is achieved with the use of a custom-designed, high-strength plastic worm wheel with optimized tooth profile. This special design allows the gearmotor to be easily back-driven.
