What does NEMA 17 mean?

NEMA 17 stepper motors' means is a stepper motor type specified by NEMA. NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (42 x 42 mm) faceplate. The Nema 17 stepper motor is larger and generally heavier than a Nema 14 stepper motor, but this also means it has higher torque. 

NEMA 17 is a hybrid stepper motor, the driving voltage is 12-36V. The maximum speed can be as high as 2500 rpm, the step angle is 1.8°(200 steps/revolution) or 0.9° (400 steps/revolution).

NEMA 17 stepper Motor Applications:

CNC routers

Precise control machines

3D printer

Prototyping machines 

Laser cutters

Pick and place machines

Linear actuators

Mid-torque precise movement applications


Nema 17 stepper motor example17HT15S4150C1

This Nema 17 stepper motor have 4 lead wires and rated voltage is 3.5 volt, rated current is 1.5A. It can be operated at lower voltage. The step angle is 1.8 deg, this means that it has 200 steps per revolution for every step it will rotate 1.8°.  Each phase draws 1.5 A at 3.5 V, the holding torque is 45 Ncm. So if you are looking for a compact easy to use stepper motor with high torque then this motor is the right choice for you.
