Lower total phase current per controller.TilmanBaumann wrote: ↑Mar 05 2019 2:36amThe benefit of winding it like that is lower phase current per driver only?
Naively I would think that a six pole motor can be hooked up to a three phase driver by hooking up the phases in parallel. Is that so?
Sorry for those questions, I just wondered if I understood that right?
Think of the power curve and smoothness of a 6 cylinder engine vs a 3 cylinder. you get similar effects from 6 phases vs 3 phases.
Yes you can, just be sure you are connecting the correct phases to each other.
For a small motor...like say an 80mm outrunner, there's not much point in it other than to mess with 6 phases, but for larger motors where controller costs start climbing in cost rapidly, there is. Ever look at what a 40kw controller costs? They are NOT cheap...something like $1200. Now look at the cost of 2 20kw controllers. You can probably buy 2 20kw controllers for a little more than half the cost of a single 40kw controller. Go higher...to like 80kw...and do that math again. Those big controllers get expensive really fast!
