Built with durable alloy steel and designed for bipolar 4-wire operation, this motor is engineered for professionals demanding precision and power in their automation projects. ## 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: Moteur costaud, câbles bien assez longs. C'est du classique et il fait parfaitement son travail. Review: 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. ## Features - Very Huge Torque - 3Nm(425oz.in) holding torque - NEMA 23 bipolar 2.24"x2.24"x4.45" 4-wire - 1.8 deg. step angle(200 steps/rev) - Rated current 4.2A & resistance 0.9ohms ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PNEPW4C | | ASIN | B00PNEPW4C | | Brand Name | STEPPERONLINE | | Customer Reviews | 4.8 4.8 out of 5 stars (412) | | Customer reviews | 4.8 4.8 out of 5 stars (412) | | Date First Available | 20 April 2015 | | Horsepower | 3 Watts | | Is Discontinued By Manufacturer | No | | Item Dimensions W x H | 5.7W x 5.7H centimeters | | Item Weight | 1.67 kg | | Item model number | 23HS45-4204S | | Manufacturer | STEPPERONLINE | | Manufacturer | STEPPERONLINE | | Material Type | Alloy Steel Metal Copper Aluminum | | Model | 23HS45-4204S | | Model Name | 23HS45-4204S | | Product Dimensions | 5.7 x 11.3 x 5.7 cm; 1.67 kg | | Speed | 1000 RPM | | UPC | 701056340255 715624558850 | | Voltage | 36 Volts (DC) | ## Product Details - **Brand:** STEPPERONLINE - **Horsepower:** 3 Watts - **Model name:** 23HS45-4204S - **Speed:** 1000 RPM - **Voltage:** 36 Volts (DC) ## Images ![High Torque Nema 23 CNC Stepper Motor 114mm 425oz.in/3Nm CNC Mill Lathe Router - Image 1](https://m.media-amazon.com/images/I/61GNLS91CQL.jpg) ## 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.
