This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-generating the gearmotor so a posture can be held even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is backed by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and light weight aluminum structure offers a rigid framework without adding unnecessary weight and is definitely easily installed to any flat surface by utilizing the base mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (electric motor marketed separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-swiftness applications that require high precision and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (in max speed)
