This post explains for the Stepper Motor NEMA 23.


NEMA 23 datasheet


Nema 23 is a stepper motor with a 2.3 x 2.3 inch faceplate. It is suitable for 3d printer, robot arm, cnc machine,etc. In low-speed applications, the stepper motor can be driven at the desired speed without missing a single step.

This stepper motor has different torque, the max torque is 3 Nm. We provide nema 23 stepper motor datasheet and torque curve. The torque is different for each operating speed, but decreases as the stepping speed increases. The reason is the operating principle of the stepper motor. The drive signal of the stepper motor generates a magnetic field in the coil of the motor to generate a step force. The time it takes for the magnetic field to reach its maximum intensity depends on the inductance of the coil, the drive voltage and current limit. As the drive speed increases, the coil maintains its full strength for a shorter period of time and the torque that the motor can produce decreases.
