Stepper motor
Ideal for 3D printers, CNC machines, or any other machineĀ that requires reliable, high torque,Ā incremental movement.
The three sizes of NEMA stepper motors hereāNEMA 14, 17, and 23ārefer 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:Ā while the NEMA 14 and 17 come with detachable cables terminating inĀ female headers, the cable on the NEMA 23 is non-detachable and terminates in bareĀ wires.
