Ron, we´re modellers, not full scale pilots

11000 W

14s3p

2,6m electric hovering and then vertical accelerating

The link doesn´t work for me, but with the video is enough


Many thanks

Para los que no sepais ingles, con bajaros el video lo entenderéis todo

Site owner changed the link, right after I posted it in several fora and mailgroups New link:

How about this 10kW Lehner 3080 with star/triangle selection:

I´ve to correct myself, with the video wasn´t enough... THAT´S A MOTOR!!!!


Ron, it´s too much for me...
What´s the star/triangle configuration?
What can you change with it?

A brushless motor has 3 sets of coils (three fases). You can connect the beginnings of all three phases, that will gave you star. You can also connect the end of one phase with the start of the next fase, that will give you delta/triangle. A motor in delta will run 1.7 times faster ( = √3) than in delta for a given voltage.


In the picture you see a 9statorteeth outrunner motor, with 3*3 sets of coils.

too expensive for me

Thanks for the explanation

Thanks for correcting me

delta = triangle
wye = star
