I think that it uses a conventional BLDC drive, what I can't figure out is what their "rotating return path" is. I suspect it just means that the current return is in the opposite direction, but through the adjacent, opposite polarity, magnet. But then, if you do that, do you need commutation at all? As for price, I think they did a motor for RCplane use at around $200. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
