## 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.
