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 :-)
