Am I right for I0 at 16V ? Would be around 35/37W of heat.

It's not linear with RPM, you probably won't see that much of a reduction on IO. I would guess 2.5-2.6A

Thanks!

OK. A so small difference is surprising me because, with fresh measures, on my motor the difference is about +30% no load current between 16V (3.75A) and 24V (almost 5A). The result is almost twice the power from 40Krpm to 60Krpm (60W to 120W) ! Thx for the informations about your new motor.

That's because of the thinner, more resistive laminations. The delta in IO is much smaller with RPM.

Thanks!

OK ! thx. That makes sense. So my motor is almost just a heat generator, althought I'm not complaining about the real performance level, but when you add the high efficiency, low temp et sensored mode of this new castle motor... I'm just wondering how resistant to dirt/bad treatment this motor could be when compared to the old unsensored one, only time would tell ?

After a very long thinking (!), I just bought this 1515 1Y sensored today, I hope it will works great and reliably for a long time.
