This motor is lighter and shorter than a typical NEMA17 motor, however it produces almost as much torque. It is suitable for driving geared or direct extruders and is used on E3D's Titan extruder.
This is popular geared Nema 17 stepper motor with a medium body and torque. It has an integrated planetary gearbox with a 5.18:1 gear ratio, the resolution reach 0.35° step angle. It's a good solution in applications that need very low rotation speeds and/or lots of torque.
This is high torque Nema 17 stepper motor with 1.8° step angle (200 steps/revolution). Each phase draws 2A, allowing for a holding torque of 59Ncm(83.6oz.in). It's good ideal for 3D printers, as well as CNC and robotics applications. The motors are supplied with a 1 metre long power cable with a 4-pin Dupont female connector already fitted.
Bipolar stepper motor, 1.8°step angle, 28 Ncm holding torque, 1.3A rated current, dimensions 42x42x34 mm, 22 mm shaft (5 mm diameter), comes with 1m lead wires.
This is the shortest bipolar Nema 17 stepper motor we have, it with step angle 1.8° and size 42x42x20mm. It has 4 wires (40 cm long, without connector), each phase draws current 1.0A, with holding torque 16Ncm (22.66oz.in). Works great with various 3D printer extruders.
