LOL - are you two using ESP or am I missing some posts here?

I've gleaned you have six wire motors and bi-polar drivers. Other than that it's impossible to say which wiring scheme would be best for you without knowing a) the torque curves and specs. of your motors (phase I, V, L etc.) and b) your PS specs. c) your driver specs. d) the demands/requirements of your system. You simply can't generalize.

I think I've gleaned that you may or may not have a problem with something overheating, is that motors or drivers or what? and what do you regard as hot?
