STEPPERONLINE 5PCS Nema 17 Stepper Motor 1.5A 12V 45Ncm (63.74oz.in) 4-Lead 39mm Body W/ 1m Cable and Connector for DIY CNC/ 3D Printer/Extruder

These are great stepping motors - I used them to build a magnetic coil winder and a positioning system for a monochromator shaft in a spectrophotometer.

The best stepper motors you can buy, without paying an arm and a leg.

Overall, this stepper motor is an excellent choice for anyone looking for a powerful and reliable stepper motor. Its high torque output, precise movements, and durability make it ideal for a wide range of applications, and it is an excellent investment for anyone looking to upgrade their machinery or build their own.

These Motors came very well packaged. Everything worked as expected.

Used to replace a motor in my 3D printer. This one works. I cannot yet say how long it will last but it seems to be of good quality.

These motors seem to work fine but I had to use their cable and not the cable that was original to my printer. Their wiring is straight through - their motors are +-+- (a+ black, a- green, b+ red, b- Blue). Many other motors are +--+ (a+, a-, b-, b+). As you can see in the picture there is a crossover in the ribbon cable.

I bought these motors not for their ability to move things, but to make songs. They worked great. I made several songs, and all 5 of them carry the same rotational frequency used to make music. While I cant vouch for their torque, I did drop one off a table and it suffered no ill effects.

Was well packaged and arrived fast. I had the bearings lock up in my stock motor and needed a fast replacement and I am very pleased that I chose this one. It runs very smooth and is quiet so my machine is running better than ever.

Many of the positive reviews have already stated the important bits. Good strong motors at a fair price, work well and at their rated specifications. But as Mark stated in his review, the cables provided with these motors will likely not line up to your 3D printer if that is your intended purpose, and you will likely need to map the connection and re-pin the connectors. In my case, I ended up replacing the black blade-style 4-pin connector with a 2.54mm JST-XH 4-pin connector for a factory mate to the printer board. Connector kits are all over Amazon here.

Connected to my ender 5 and it would just rotate back and forth. Replaced with a different motor and it works fine. 0/10
