3 Pack Nema 17 Stepper Motor 1.7 A 0.59 Nm 84 oz.in 48mm Body w/ 1m Cable & Connector for 3D Printer/CNC

Well they work fine. I am using these steppers for a school science project. Just wanted to start out saying! These are 100% not even close to 84 oz.in they are all ranging from 58-62 oz.in in fact 58.3 out of one/ 59.3 out of next/ 62 on button with 3rd. Mine you all driven same setting and only used one driver to test all 3 one at time. gonna give me all this ??? questions what not. Just as a control! used a 90oz.in nema 17 stepper and it read 90.2 oz.in so just saying. lol whole point of these motors was to do this type of science example for a school project! So not like this was some kind of redneck thing done in a shed on youtube! Just saying clearly not 84oz.in and not even close to same coil structure those number where very off for 3 steppers suppose to be identical! I think this another one of those cases where they kinda fib a bit to sell an item!They work alright. I could see these cause of the huge gap in how each is made causing some real problems with like 3d printing and such making off prints.when coils are not same they don't move the same!

Issues with end play in 1 motor - wave washer was broken, another binding and bearing seat in housing had to be cleaned up, and third was fine. Typical generic/low cost steppers with problems that come with not spending more for quality brand.

Zyltech Stepper Motors have the best torque per watts that I have found ANYWHERE on the net. These means they run cooler with the same required torque. I run my stepper motors in 60c to 70c environment and these seem to run the "coldest"These need to have a connector at the motor so the wire can be replaced. Most other motors have a connector at the motor for easy maintenance.

very fragile wiring. right out of the box one of the motors had three broken wires. there is no strain reinforcement where the wires come out of the motors. The wires are a little light and stiff and unmanageable. If you're going to use these put some epoxy or hot glue in there or be prepared to take them apart and re-solder wires. otherwise the motors are quite well built.

I ordered this three pack because they're cheap. They work very well. I'll definitely look at getting more Zyltech parts in the future!

Using for a CNC project. Came packaged together nicely. Work perfect, very good quality. I would purchase again. Especially like the length of the connection wires and having the connectors.

Seem to be more efficient than the crappy Nema17's they replaced. Less amperage is producing more torque.

Motors are running great as of right now, 2 weeks after purchase.
