Just wondering if those who have been paying attention or done this type of thing have any insight into what it takes to have a dual motor setup. The Agnis only need one controller, but how much of a pain is it to get 2 motors and controllers dialed in? Is one controller better and easier than 2? I'm think the KISS method applies.
Also, what are the real differences to running motors parallel or in serial? And how might that affect the battery cells?
Here's what has been going through my head. I'm thinking of a dual Motenergy motor setup with a max of 75kW going to both motors, or 37.5kW each. Now, do the motors care how the 37.5kW is delivered to each of them? Because it could be (well any combo, but) 187.5v at 200A or 93.75v at 400A at each motor. For some reason I have it my head that the higher voltage lower amp way of doing things would mean down the line there would be less stress put on each individual cell in the battery pack. I could just run 2 of these motor kits, but it would seem to be cheaper an easier to run one controller.
Lets look at that for a second. Say I ran the dual Sevcon setup. How much of a pain would that be? And then, I could only get 84v out of the Sevcon, so I would be running about 450A per motor, which is well within Sevcons 550A. What performance difference would I notice between those 3 different voltage/amp combos? Obviously it would be for a race bike so that has to be taken under consideration.
Ok, I've boiled it down. Wire the motors for serial or parallel? And, within a power (kW) limit is more voltage or more amperage better? Then, I can start thinking about this hypothetical bikes controller.
Thank you for any insight you can provide. And apologize if I am rehashing old subjects.
