I think you should see about 1/2 the iron losses with our motor, vs a motor with standard .35mm laminations. In our motor, the iron losses are the minority losses -- more important is the copper losses. At 5 milliohms, the iron losses are about 50 watts at 100A.
Thanks!

This new motor is really efficient ! the hpi 2350kv (also made by castle for hpi but low cost) is more than 5A at 24V no load (125W of heat...), almost twice the current of the new castle 2200kv sensored at the same voltage ! Not bad at all. My current motor need a big fan (delta 40*28mm FFB0412VHN 15.79CFM 1400LFM) to stay cool for long time run (offroad track with turnigy graphene 4S 10000mah, 30 to 40 min run time with 18 pinion 48 spur), I think that with the castle, no need for a fan.
Raaahhh I think I need to spend some money...
