Brad, I am someone who is most certainly NOT an expert in your field, but I try to approach any problem by finding its borders first. I do know that switched reluctance (SR) motors are very enticing due to their simplicity and therefore low cost, but they are mind-numbingly difficult to control well. And an EV is s very broad-spectrum application, so good control under a wide variety of conditions is a necessity.
Several years ago I read an article on a new suite of SR motors that boasted a new level of control, but they don't seem to have taken the market by storm yet. Seems to me you'll need a mountain of expertise in SR motor theory before you start. Because that's what others have had at their disposal and haven't created an EV-suitable SR motor yet. TI and probably others have chips that are specifically designed for SR motors and they've devoted a lot of development time to the application. This is well-traveled ground. I know this appears to be throwing cold water on your plans, but in fact I'm hoping you have some new ideas that might bring SR motors to EVs. Do you? Can you share?
