how about 2 brushless motors (modelairplanes), 2 propellers, 3 wires for motorsupply and as vertical. Only question: what about the 3 chokes at 15 kV rf?

 

Regards, Peter, dj9dw.

 

 

Dear Peter, LF Group,

 

Simple – just design the motor drive to run from a 137kHz AC supply – then you won’t need chokes :-)

 

Cheers, Jim Moritz
