I bought a couple of mystery motors on ebay http://www.ebay.com/itm/151913003555?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT because mysteries are fun.
I've been trying to figure out the correct hall/phase combination with a Lyen 123770ST controller. After trying all combinations, the lowest no load (unbuilt in a truing stand) amp draw is 3.9 amps measured with a cycle analyst (correct shunt value) with a 36v battery around its full capacity charge of 41.8v (~160w). The hub spins around 500rpm at this voltage, or a theoretical ~440rpm at 36v. Both of these numbers seem really high, but I've gone through all of the possible combinations and can't find anything that is either a lower rpm or lower power consumption. Any chance this is normal for this hub? Not much for marking on the hubs. EDIT: I think these might be Mac motors, see below
