Default Potential Relay for phase converter

You can get a Steveco No. 90-65 potential relay rated 50 amps at a motor or
AC service establishment.
They are around !2 - 15 $.

If you or a friend can get into some experimenting, you can build

hysteresis
into a DPDT relay by using one set of contacts and some power resistors
wired to add a "boost" to the coil voltage once the relay pulls in.
Resistance and power rating would depend on the particular coil and

current.
Seems like something that ought to work but that is only ni theory.

I have to make a 10HP rotary converter.. what do you suggest for the
capacitors and what are the potential relay on/off voltages? I might
whip up something electronic to switch a regular contactor if someone
can tell me what it should do.
