Hi,
I am building a machine with 3 sixfilar coils and a small rotor with three magnets. First I ran a test with only one of the coils -- trigger and one power strand, found the sweet spot as you usually do, and nothing unusual when changing the 1k pot.
I then mounted two more coils, connected as slaves with one power strand each. Now when I run it I find a sweet spot at first as usual, but when I back off a little on the pot suddenly the already fast spinning small rotor accelerates like mad. I increase a little on the pot again and find a new sweet spot without the rotor decelerating, its still spinning really fast. Anybody that can explain what is happening and why it suddenly accelerates and finds a "new balance"?
This seems like a powerful machine already and I still have four strands on each coil to connect... It spins really fast so maybe I should get a bigger rotor and more magnets.
The coils are AWG 20 (trigger also) and I'm using 2N3055 transistors.
And: A big thanks to Peter and Aaron for the Bedini Beginners- and Intermediate sg handbooks! Very interesting, informative and well-written. Thanks!
