High Torque Stepper Motors NEMA 17

Nema 17 (42mm) High Torque Hybrid Stepper Motors

Motion Control Products range of high torque NEMA 17 Hybrid Stepping Motors are available with a holding torque up to 43Ncm.

A high torque stepping motor output more torque than standard hybrid stepping motors due to the use of powerful rare earth magnets instead of the traditional permanent magnets. The motors are 1.8 degrees-per-step have single or double shaft and the option of optical encoder and planetary gearbox available for most motors.

A mid size hybrid stepper motor we also supply NEMA 8 (20mm), NEMA 11 (28mm),Nema 16 (39mm), NEMA 23 (57mm) and NEMA 34 (86mm) versions.

Applications:

Typical applications for Nema 17 stepper motors include: 3D printers, Prototyping machines, Telescopes, Pick and place machines, Linear actuators, Analytical Devices and Medical Instruments  and CNC machines.
