Example: You use A and C phase and you switch to C and B phase
I can pull out some of my references that do get into the math of it, but with 3 phase motors in general, changing any two connections will give you a rotation oppositie of that which you started with.
Without math, it has a lot to do with the phase relationships within the windings and the poles of the rotor/armature, and the fact that the magnetic flux within a winding is 90 degrees out of phase of the current applied.
My scanner decided it did not want to function anymore, so I will have to look for the simplest explanation with as few greek letters as I can find so I can enter via ASCI format.
You achieve dynamic braking by switching two connections, and as long as the heat can be dissipated within the motor effectively, it is not a problem.
I guess one question that ought to be asked too, due to how you phrased your question, are you trying to operate three phase power off of your normal single phase house supply? If so, there is an easy way to do that which has a proven track record.
:In a open wye delta connection and you have two phases hooked to the high side and switch one later on will it change the rotation in the secondaries and why?
