Review: These are pretty well-made. I think my only real complaint is ... - I was surprised to see such a large stepper for so cheap, so I decided to buy one and see how well it was put together. Well, I've since bought two more, and I plan on using them in a CNC router/milling machine. These are pretty well-made. I think my only real complaint is that the shaft is a D-shaft and not a keyed shaft, but I suppose it probably won't matter in the end. Can't wait to get the machine running. I did test the motor, and while I don't have a way to verify the torque rating, it seems relatively accurate. Given the price, I don't think I'd mind if it only really did 75% of the "rated" torque.
Review: Motor - Was ok but smaller than expected

## Questions & Answers

**Q: where can i find a schematic of the dimensions for this nema 23 stepper motor?**
A: Google "23HS45-4204S datasheet".  23HS45-4204S is the part number of the motor.  The first page of links will have the motor datasheet which includes a mechanical drawing for the dimensions and a electrical schematic for the wiring.  When I run the google search the first link I see is a sales page that includes the datasheet in the form of a PDF link.

**Q: How many wires is this?**
A: 4

**Q: Will my tb6600 driver work with this motor?**
A: It should work, the drive is on the smaller side so it might overhear if you use at a higher duty cycle.

**Q: What are the motor specs for Mach 3 setup?**
A: Ask the supplier of your main board, i dont think its determined by motor.

### ⭐⭐⭐⭐⭐ Great Motor.
*by B***N on January 27, 2019*

Bought these for my first CNC build. Motors work great without issue. Once I received them, a quick web search of the model/part number gave me a data sheet, which gave me everything I needed to hook them up. If you are a newb like me, keep in mind the 4.2a current rating. A cheap $7 driver wont cut it. These bad boys need big-boy drivers. When construction was complete, and testing began, cheap drivers worked fine. When cutting, the cheap drivers just couldn't keep up. Spend the money to buy good drivers to take full advantage of these motors performance.
