What Are NEMA 23 Stepper Motors?
A NEMA 23 stepper motor is a brushless DC motor designed to move in precise increments or "steps" rather than rotating continuously like a conventional motor. The term "NEMA" refers to the National Electrical Manufacturers Association, which standardizes motor frame sizes.
The "23" designation indicates a faceplate size of approximately 2.3 inches × 2.3 inches (57 mm × 57 mm). While all NEMA 23 motors share the same mounting dimensions, they may differ in torque output, current ratings, shaft configurations, and winding designs.
These motors are commonly used wherever precise positioning, speed control, and repeatability are required.
How NEMA 23 Stepper Motors Work
NEMA 23 stepper motors operate by converting electrical pulses into mechanical movement. Each pulse sent by the controller causes the motor shaft to rotate by a specific angle.
For example:
- 1.8° step angle = 200 steps per revolution
- 0.9° step angle = 400 steps per revolution
This precise stepping mechanism enables accurate motion control without requiring complex feedback systems.
The motor driver energizes different windings in sequence, creating electromagnetic fields that move the rotor step-by-step. This controlled movement makes NEMA 23 stepper motors ideal for applications requiring exceptional precision.
