I've been using it all weekend, and so far everything is working out pretty good. I haven't gotten around to reinstalling my Flexion extruder kit back on after changing back to the stock block with the all-metal upgrades, but this thing can definitely power that. Not that noisy (although nothing is that noisy when sitting next to the fans that came on the Wanhao), and haven't had any clogs or skipped steps yet. I know the stock motor is 34mm, but a 6mm difference is negligible for me, and the tradeoff in torque gain was worth it. One note though, I had to remove some metal from the heatsink to make it fit, since the shaft is a bit longer than stock as well. Also, be sure to adjust your voltage, because the stock motors run at a pretty significantly lower voltage than these. Review: Solid performance and a good price - I use a lot of stepper motors and I've never had an issue with these. They work well with every driver I've used them with and the threading and dimensions are always very accurate for installation in a variety of projects. ## Features - 45Ncm(637ozin) holding torque - NEMA 17 bipolar 165"x165"x157" 4-wire - 18 deg step angle(200 steps/rev) - Rated current 2A & resistance 11ohms ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PNEQI7W | | Best Sellers Rank | 305,860 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 317 in 3D Printer Motors | | Brand | STEPPERONLINE | | Customer Reviews | 4.5 out of 5 stars 217 Reviews | | Horsepower | 1.1 Horsepower | | Item Dimensions W x H | 42W x 42H millimetres | | Item Weight | 308 g | | Manufacturer | STEPPERONLINE | | Manufacturer Part Number | 17HS16-2004S | | Material | Aluminum Copper steel | | Model Number | 17HS16-2004S | | Product dimensions | 42W x 42H millimetres | | Shaft Diameter | 5 Millimetres | | Speed | 200 RPM | | UPC | 191579036757 190657066570 190657464598 714485343629 701056337583 701056510245 | | Voltage | 24 Volts | ## Product Details - **Brand:** STEPPERONLINE - **Horsepower:** 1.1 Horsepower - **Product dimensions:** 42W x 42H millimetres - **Speed:** 200 RPM - **Voltage:** 24 Volts ## Images ![Stepper Motor Nema 17 Bipolar 40mm 64oz.in(45Ncm) 2A 4 Lead 3D Printer Hobby CNC. - Image 1](https://m.media-amazon.com/images/I/61+t-Jj8sFL.jpg) ![Stepper Motor Nema 17 Bipolar 40mm 64oz.in(45Ncm) 2A 4 Lead 3D Printer Hobby CNC. - Image 2](https://m.media-amazon.com/images/I/61bCg4h8f+L.jpg) ![Stepper Motor Nema 17 Bipolar 40mm 64oz.in(45Ncm) 2A 4 Lead 3D Printer Hobby CNC. - Image 3](https://m.media-amazon.com/images/I/41m9NLMDsLL.jpg) ## Questions & Answers **Q: What i be able to use this on my 2001 nissian primera** A: Sorry, this motor will work for the previous generation Nissan Primeras (1990-1996), but not the 1997-2002 models, like yours. What you're gonna want for your 2001 is this: https://www.amazon.com/Adafruit-Small-Reduction-Stepper-Motor/dp/B01BMRR0FM/ref=sr_1_17?ie=UTF8&qid=1537639600&sr=8-17&keywords=28byj-48 **Q: Do you have a preferred stepper driver for use with this stepper motor? Thanks. :-)** A: If using it in a 3D printer look into a TMC2208 or TMC2209 if your control board support UART-configured stepper drivers. **Q: What's the drive shaft's measurement, 5mm?** A: Yes, it's 5mm shaft. **Q: Is this an ac or a dc motor?** A: Well, I don't know if you know about stepper motors, but it is DC. Depending on your application, it will work from 12-24V. It uses about 2 amps, but will work fine at about 1.1 amps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great motor upgraded for Wanhao i3 extruder if you don't mind the small loss in space. *by P***E on 18 July 2016* I bought this motor is replace the weak extruder motor on my Wanhao Duplicator i3 v2 that I recently changed to a RAMPS 1.4 board.

They work well with every driver I've used them with and the threading and dimensions are always very accurate for installation in a variety of projects. ### ⭐⭐⭐⭐ Good motor, Great torque, but be careful and do your research before you pick your driver! *by D***. on 25 April 2016* So far it's a good little motor, however the low 1.1ohm coil resistance is causing me some issues with one of the L298N H-bridge modules I also bought off amazon. In order to drive this motor you either need a current limited power supply <2A or you need to drive it at about 2V. If you supply it with 12V as stated in the spec sheet, it will draw about 11A, which is plenty to smoke-check both the motor and your H-Bridge. If you're going to use this with the L298N, you must use PWM, or wire 4-8ohm@5W resistors. If you don't know what any of this means, don't use it with the L298N modules you will end up smoke checking the motor or the bridge. ## Frequently Bought Together - STEPPERONLINE Stepper Motor Nema 17 Bipolar 40mm 64oz.in(45Ncm) 2A 4 Lead 3D Printer Hobby CNC - HiLetgo 5pcs A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap Suitable for Mendel Huxley Arduino - HiLetgo 2pcs A4988 V3 Engraver Drive Shield 3D Printer CNC Drive Expansion Board for Arduino 3D Printer CNC --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/175548717-stepper-motor-nema-17-bipolar-40mm-64oz-in-45ncm-2a](https://www.desertcart.gr/products/175548717-stepper-motor-nema-17-bipolar-40mm-64oz-in-45ncm-2a) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-16*
