The main difference is the step angle of the motor. 3 phase motors are 1.2deg(sometimes 0.9Deg) and 2 phase is 1.8Deg. This translates into a slightly smoother action from the 3 phase motors, they are also slightly stronger and hold torque higher up the speed curve. However, they only sell 3 phase motors with 50Vdc drives up to 3Nm with Nema 23 motors.

This is the one I use and would ask about. Slightly more Nm than required but can be run on AC or DC power up to 70Vac or 100Vdc. They come with 3mtr length encoder cables but if you require longer then just ask and they will provide up to 7mtr lengths.

This is why I say always email them for a price rather than paying the listed price, they will often lower the price. Plus if you are prepared to pay outside of ebay or Aliexpress they will knock a little more off because not paying fees. I do this all the time with Lichuan and BST and never had any issues with either.

I was skeptical at first, but I checked nema 23/24 sizes and I did not know the mounting holes were the same distance. I'm totally getting these then. Thanks!

The only difference between them is NEMA 23 width is 57mm NEMA 24 are 60mm. You can get NEMA 24 with 50mm Hole spacing if required.

Just to make you aware that depending on your country then you will pay Vat and possibly Import tax and often the courier will charge a handling fee. In UK I only get charged for VAT and handling charge of approx £15-20.
