Description
These motors provide a mighty 50N-cm (70oz-in) of torque while running at 1.5A! Heaps of power without stressing out your stepper driver - perfect for direct-drive / bowden style extruders!
The motor's shaft has been ground flat, making it easy to get a good grip with a pulley, drive gear - or anything that uses a grub screw, really.
Another handy feature of these motors is their detachable leads - this makes installation a breeze, and it's easy to redo your wiring later if you'd like. We've had the included cables customised to plug straight into a RAMPS board, so installation of these motors is literally plug-and-play!
We recommend these motors for geared / direct-drive / bowden extruders - they provide enough torque to handle nearly anything. They'd also be suitable as axis motors for delta-style 3D printers, where high-torque is a necessity. For X/Y/Z motion in a cartesian printer, our lighter 34mm steppers are a great choice.
