Pay attention to the inductance of the motors. If the square root of the inductance isn't 1/32nd of the voltage you're supplying to it (or at least close) then performance at high speed (which you need for cutting wood) will be compromised. Here's a chart for a motor like you're talking about: https://www.automationtechnologiesin...100-50-4BM.pdf It has 2.5mH inductance per phase, which is pretty good for a motor that size; according to the formula above it wants about 40v to run at full speed. Your Leadshine drives can handle 50v, so the combination should work pretty well. But all motors with the same holding torque don't necessarily have the same inductance, so make sure to check that before you buy.
