Nema 23 Stepper Motor
A NEMA 23 stepper motor uses the standard 2.3-inch (57.15 mm) square faceplate. The frame number tells you the mounting interface—electrical ratings depend on the specific model. Most NEMA 23 motors are hybrid steppers, using a permanent-magnet rotor with a variable-reluctance stator structure.
A common full-step angle is 1.8° (200 full steps per revolution); microstepping in the drive can increase commanded resolution. Stack length and winding choice influence holding torque, heat rise, and overall motor length. Lead options are typically 4, 6, or 8 wires for bipolar or unipolar drive methods. In common configurations, phase current is often in the 2–6 A range and holding torque is frequently around 1–3 Nm, but both are model dependent and should be confirmed in the datasheet.
NEMA 23 stepper motors are commonly used in CNC axes, 3D printers, robotics mechanisms, packaging equipment, and laboratory automation. For selection, verify torque at your operating speed, driver voltage/current capability, mounting hole pattern, shaft dimensions, and duty cycle. The torque–speed curve and electrical table for the exact part number are the references for final confirmation.
