My own answer to the "motor too big, need easy starting" problem was
to use two idlers, to be started in sequence. Mine are 10 and 7.5 HP.

Yes. Mine was slightly more clever than this.

1) I used two contactors instead of 3. Which worked well, they just
needed to be wired differently.

2) The first motor had a capacitor on legs 1-3. It assisted with
starting, but resulted in unbalanced 3 phase.

3) The second motor had a capacitor between legs 2-3. When it was
connected to the network, the capacitors became equal between legs 1-3
and 2-3. That resulted in a much more balanced 3 phase.


But mine is better than yours because if the incoming supply power drops out
then it kills them all and i have 400 amps feeding the ****ing buss so
nanaanananna.

Bye bye followups set crossposting removed.
