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

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.

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.

Some of the best stepper motors Ive bought.

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.

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.

The web page indicated that these motors had removable wires but they were hard wired to the motor and I had to add connectors in ordered to have them work on my printer.

Great product well priced

Everything works well as expected. I mean, that what you expect out of a product, right?

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.

good motors. They have gotten ridiculously cheap! I cant say anything about the internal bearing quality - which is a BIG factor if youre running them with a belt.
