Stepper motor

Ideal for 3D printers, CNC machines, or any other machine that requires reliable, high torque, incremental movement.

The three sizes of NEMA stepper motors here—NEMA 14, 17, and 23—refer to the size of the motor and hence the amount of torque that the motor is capable of; the larger the motor, the more torque (specific torque values are in the tables below).

Please note: while the NEMA 14 and 17 come with detachable cables terminating in female headers, the cable on the NEMA 23 is non-detachable and terminates in bare wires.

Wiring

For the NEMA 14 and 17 stepper motors, the red (+) and blue (-) wires control bipolar driver A and the green (+) and black (-) bipolar driver B.

For the NEMA 23 stepper motor, the red (+) and green (-) wires control bipolar driver A and the yellow (+) and blue (-) wires control bipolar driver B.

Perfect for what I needed at a reasonable price compared to other companies. My old motors gave up on the CNC they just couldn't handle the torque needed to push through the material. These can, highly recommended and super fast delivery.
