## Overview

The STEPPERONLINE High Torque Nema 23 CNC Stepper Motor delivers a commanding 3Nm (425oz.in) holding torque with a precise 1.8° step angle, housed in a compact 114mm frame. Rated at 4.2A current and built with durable alloy materials, this motor is engineered for demanding CNC milling, lathe, and router applications. Trusted by professionals for its reliability, smooth operation, and compatibility with standard bipolar drivers, it’s the go-to choice for millennial makers and managers who demand both power and precision.

## Description

This is the strongest model for Nema 23 stepper motor, it with 1.8 deg. step angle (200 steps/revolution). Each phase draws 4.2A, allowing for a holding torque of 3.0Nm(425oz.in). Electrical Specification: * Manufacturer Part Number: 23HS45-4204S * Motor Type: Bipolar Stepper * Step Angle: 1.8 deg. * Holding Torque: 3.0Nm(425oz.in) * Rated Current/phase: 4.2A * Phase Resistance: 0.9ohms * Inductance: 3.8mH+/-20%(1KHz) Physical Specification: * Frame Size: 57 x 57mm * Body Length: 113mm * Shaft Diameter: 10mm * Shaft Length: 24mm * D-cut Length: 20mm * Number of Leads: 4 * Lead Length: 400mm * Weight: 1.8kg Connection: Black(A+), Green(A-), Red(B+), Blue(B-) Warning: Make sure the motor connect to a constant current or chopper drive controller before you test motor. Connecting the motor directly to a power supply will destroy the motor.

Review: Fonctionne parfaitement - Moteur costaud, câbles bien assez longs. C'est du classique et il fait parfaitement son travail.
Review: It's high torque, works well - used these for a rail system and an arduino build that required a good 50lbs of lift across two motors. These don't disappoint. They can heat up, so I set the stay current to 50% and they still hold steady but stay cool. Good motor.

## Questions & Answers

**Q: Is there an adapter available to fit the 11mm input shaft of a 20:1 speed reducer nmrv030?**
A: They are researching it here, where the motor is sold. Wish I had an answer, but at least I'm not THAT guy.

**Q: How many RPMs will the motor run before the torque drops in half?**
A: The torque is highest at a slow 10 RPM. The torque drops linearly at the RPM increase. It starts to skip pulses because of low torque at about 200 RPM. I had to add a 100 tooth to 36 tooth xml timing pulleys to increase the torque.

**Q: Where can I get a gear that works with this 10mm shaft? Most of those I've seen are in standard, not metric units.**
A: I've had luck finding pulleys on EBay. I'm not sure about gears but it would be worth a shot if you haven't already looked. Also you could buy something to fit on a 3/8in shaft and drill it out to 10mm.

**Q: What is the maximum power output in Watts? I’m sure it’s higher than the 3W they have listed.**
A: Hello, 

The power is calculated as:
P = V *I* # of coils active, or equivalently 
P = I^2*R* # of coils active
For instance, if only one coil is active,
P=4.2^2*0.9*1 = 15.87 watts
If two coils are active, such as when the motor is holding a position, then the power doubles, which comes down to 31.75 watts. 

Hope this helps,

Hector
