won't work with a series controller.
I think that it is actually configurable. If you look at this document:
It says the rotor types are configurable. Three of them can be AC IM type. As far as the permanent magnet type goes, I am not sure if it is BLDC or PM AC type..
It was interesting that this was pointed out as Vaxosystems offer only the PM type. EvDrive.com does not say what is the type of the systems offered. But looking at the costs it might be the PM type..
While the PM is slightly more efficient, the AC IM stands out in cost, ruggedness and environmental friendliness(does not use rare-earth PMs).
It would be interesting to know what the cost of a Remy250 AC type motor would cost..
