JMC closed loop steppers - anyone have any experience?

If your going closed loop make sure the motors are 3 phase. They are much smoother and give more power. Lot of the larger motors are 2 phase.

Thanks for the replies. I need Nema34 motors which seem to be rated at 4, 4.5, 8.5 and 12NM. Coincidentally, I was just thinking about the issue of two or three phase motors, but it does appear that both the Leadshine and JMC Nema34 motors are two phase.
