I've been reading some more about these motor's. In Germany some rc-boaters have been using them and are reporting they are 0.5-3% less efficient as comparable lehner motors and that they weigh less than the lehners .

There isn't much yet on the web about these motors, but the few reports are positive.

I don't think google translate can handle this:
Quote:
Tenshock 2220/8 vs. LMT 1930/6
Beide Motoren decken praktisch denselben Drehzahl- und Leistungsbereich ab und lassen sich gut direkt vergleichen. Hier mal die Werte MEINER BEIDEN EXEMPLARE.

LMT: (255g, 2-Polig)
Ri: 5,1mOhm
Io: 3,7A (8V)
Lastdrehzahl: ca. 3450rpm/V bei 50A

TS: (170g, 6-Polig)
Ri: 5,1mOhm
Io: 3,9A (8V)
Lastdrehzahl: ca. 3400-3425rpm/V bei 50A

Bei den Lastmessungen hat der LMT zwar bei Vollast 1% und bei Teillast 2% mehr eta, dafür ist der TS gut 1/3 leichter und hat einen leichteren Rotor mit weniger Massenträgheit. Im Boot wird das vermutlich den geringen Wirkungsgradnachteil kompensieren.

Und...der TS kostet nur die Hälfte eines 1930 HiAmp.
