STEPPERONLINE 5PCS Nema 17 Stepper Motor Bipolar 2A 84oz.in 48mm 4-Lead for 3D Printer/CNC

The stepper motors are rated at 2A where most others are below this current level. I have used them without any issues. They run very quietly. I am using them in a CNC wood mill. I recommend these without any reservations.

I've used StepperOnline steppers before and this newer nema 17 2004's doesn't disappoint. I'm using these along with nema 17 1004's for Voron 2.4 build and it has plenty of power and low noise. I highly recommend these if you are building a Voron.

Finally got to play with these things today. Really, just had time to put the ramps and arduino together and hook 'em up. So far, they work just fine. Other reviews mentioned a lack of connectors on the wires, which I had prepared for by purchasing a pack of dupont connectors and a crimper for them. These things had connectors on them, apparently compatible with RAMPS 1.4. A minor downside (nothing to write home about, and likely specific to the application you'd be using these for) is the cables falling around like noodles after you untie them. Definitely a good purchase. Might end up getting more.

Great Steppers, worked wonders for a 3d printer. Plenty of power and great accuracy for the job. OSM also has additional information about their products on their website so you can properly match a driver/controller and power supply with the stepper motor. My only complaint is the wires are free floating with no organization once so ever, and no I’m not a big fan of spaghetti wiring, nothing a little heat shrink won’t fix but still. Also others may want to know that these come with no connector on the end of the wires, which to me is understandable and I don’t care, but you might.

excelente motores cumple contadas las expectativas

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.

I bought a bunch of cheep steppers somewhere else to get started but the first thing I noticed was how loud they were but what’s worse was the heat. I bought these to replace the cheep ones and I sure glad I did. These run so quiet and cool especially with TMC drivers! I’ll be ordering more!

Unos motores demasiado buenos stepperonline lo mejor de lo mejor

Stable motors, strong, never had any issues. Delivery was good too 👍🏻

Decent product, as described.
