Nema 23 Stepper Motor 4.0A 3.0Nm(450oz-in ) Our RTELLIGENT stepper motor is specially designed for accurate control of position and speed. The biggest characteristic of step motor is "digital" For each pulse signal from the controller, the stepper motor driven by its runs at a fixed angle ("One step" for short) General specification Step accuracy: ±5%(synchronizing, no-load) Temperature rise: 80℃Max Ambient temperature: -10℃—+50℃ Insulation resistance: 100MΩmin.500VDC Voltage resistance: 500VAC for one minute Radial runout: 0.06Max.(450g-load) Axial runout: 0.08Max.(450g-load) Electronic Specification of Step Motor Size Warning Warning : Make sure the motor is connected to a constant current or chopper drive controller before testing. Connecting the motor directly to a power supply will destroy it.

Could have ordered the next size down really as loads more torque than I thought. No regrets. Review: Great, powerful motor with lots of torque - I bought this motor alongside a TB6600 stepper driver and controlled it with an Arduino. It's powered by a 24v power supply and overall I'm very impressed by this motor. It gives out a lot of holding torque, and the turning action is very smooth and precise. I used this to tilt a platform and aim a light beam at a certain point, and I have had no problems with the accuracy of this motor, even without using microstepping. Great little motor at a good price, can easily recommend (assuming you have the appropriate driver and knowledge to run it) ## Features - Features: 2 phase, 1.8 degree step angle, 3.0Nm holding torque, 4.0A-5.0A Rated Current, 4-wire, 24-50VDC operating voltage(Recommend 48VDC) - Advantage: The stepping motor is featuring low vibration, low noise, low heating, high speed - Digital Motor: With the digital character, the step motor can control position and speed accurately - Default Connection: Black (A), Red (B), Green (C), Blue (D) - Application: The stepper motor is widely use for 3D printers, medical equipment, industrial equipment, laser CNC machine, automation devices ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V9RMWMK | | Best Sellers Rank | 104,825 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 78 in 3D Printer Motors | | Brand | RTELLIGENT | | Customer Reviews | 4.9 out of 5 stars 30 Reviews | | Manufacturer | RTELLIGENT | | Manufacturer Part Number | 57 MOTOR | | Material | Alloy Steel | | Number of items | 1 | | UPC | 791315155058 | | Voltage | 48 Volts | ## Product Details - **Brand:** RTELLIGENT - **Manufacturer:** RTELLIGENT - **Material:** Alloy Steel - **Number of items:** 1 - **Voltage:** 48 Volts ## Images ![Nema 23 Stepper Motor 3.0Nm/425oz.in 4-lead 57x57x100mm 8mm Shaft High Torque Step Motor CNC Mill Lathe Router - Image 1](https://m.media-amazon.com/images/I/61qHRHamFdL.jpg) ![Nema 23 Stepper Motor 3.0Nm/425oz.in 4-lead 57x57x100mm 8mm Shaft High Torque Step Motor CNC Mill Lathe Router - Image 2](https://m.media-amazon.com/images/I/61FnGmrQexS.jpg) ![Nema 23 Stepper Motor 3.0Nm/425oz.in 4-lead 57x57x100mm 8mm Shaft High Torque Step Motor CNC Mill Lathe Router - Image 3](https://m.media-amazon.com/images/I/61+3WBOQvaL.jpg) ![Nema 23 Stepper Motor 3.0Nm/425oz.in 4-lead 57x57x100mm 8mm Shaft High Torque Step Motor CNC Mill Lathe Router - Image 4](https://m.media-amazon.com/images/I/71gMh7+CVBL.jpg) ![Nema 23 Stepper Motor 3.0Nm/425oz.in 4-lead 57x57x100mm 8mm Shaft High Torque Step Motor CNC Mill Lathe Router - Image 5](https://m.media-amazon.com/images/I/619nzPk0TrL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fine quality. *by N***T on 8 August 2025* Arrived well packaged and undamaged.
