Turnigy 120-70 8.6kW and irfb3006?

I hope the no load current isn't 17A

<edit>
I just renamed this thread to start a discussion about the right FETs for an infineon mod.
I think 60v is more than enough to heat up the skirt bearing. I guess that's where the high no load current comes from.

So irfb3006 would be my choice ATM.

just got me one...

That is a pretty decent looking motor, for a good price too.

Keep us updated with your progress of finding a controller for that beast.

How many stator teeth / magnet poles does it have? 12/14?

It's 24 teeth, 28 poles. We have a pretty big thread started on it all ready. I would love to have you take a look and give your insight.

I hope to get some halls glued in the stator and then fire it up with a sevcon millipaq controller. It was designed for the etek brushless and this one is known to have a very low phase resistance as well.

If testdrives work well, I'll try to use a modified infineon in combination with a manual wye/delta switch and/or a centrifugal clutch.

@ mods: we could use a new controller-mod section in the forum tree.
There are several guys starting with DIY controllers or heavily modding existing ones.
IMHO this belongs in a new category.

BTW: testing such a monster will make the turnigy WattsUP quite useless. :lol:

I have a 400A amperemeter too, but it's not quite handy during a testdrive.
How much current is allowed on a CA? ( link?)

Can we not use this forum for controllers as well? It is Motor Technology.... We're trying to avoid too many sections.....
