Worm gear reducers have a distinct advantage of having very low audible noise. The right angle output configuration result 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 plastic worm wheel with optimized tooth profile. This special design allows the gearmotor to be easily back-driven. The high efficiency allows the use of a smaller, more energy efficient motor to achieve the same output power versus a standard worm gear reducer. The 5700B brushless motor offers extended life, high efficiency, and controllability for demanding applications.
