Quite sure it¡¯s the reverse Cliff. It¡¯s the phase perfect that delivers smooth power... Bill Belanger?

One of the members? did a work of of the PP vs a rotary? the PP?
produces dirty power? uneven spikes on the phases where as the
rotary can be tunes to be sm,ooth as glass.
Dunno why they suggested the PP but I wouldn't use one.

When I bought all my machines, I asked Felder and the
strongly suggested Phase Perfect. I believe they also said all
the electronics would be covered under warranty if I used PP. Other devices might be questionable concerning warranty. It
was a bit of a choke on the price but I have never had any
issues. Yes I believe it was L2 for the electronics.

Why would you chance ruining your equipment when you can get a Phase Perfect and have none of these issues?
Hi Dave, which model do you have and what equipment are you running with it, does the equipment have electronics like felder powerdrive? I ask because felder tells me no more than 250v and some RPC can have a large variation between legs.
American rotary also told me that if I wanted to run a bandsaw or dust collector then I should get the ¡°ADX¡± because of the harder startup
? Mark, ? They both make noise.? I have the
motor for my American Rotary? RPC up in
the attic and I can hear it but it isn't
very loud.? I'm in Shreveport so not too
cold in the winter but blisteringly hot in
the attic during the summer.? I also have
a PP in the shop and it buzzes.? Neither
are overly objectionaable Dave
Have a few more questions,?
I know this is not most important factor in making a decision but which is noisier a PP or RPC In small shop 24¡¯ x 24¡¯ when not using machines and if on is it a distraction? Can the RPC motor be installed in a unconditioned space or outdoors? Not to worried about heat but temps are 0f to -10f for a good 3 months here and do go to -30f on occasion during the winter months?
? Thanks
everyone for the excellent
responses, sounds like i have
options be it VFD, RPC or PP.
Will revisit this post for more
q&a if things workout. Regards, Mark On

?Brian,
I
did not go into the details
but if VFD is used then it can
(probably should) be used to
brake as you are suggesting
but I would disconnect the
electric brake on the machine
as there could be some
interactions. Electric brake
circuits on the machine will
be loosing power while trying
to brake.
VFD
may also need external brake
resistors.

a 10hp RPC will work. And yes,
a VFD works just fine and you
can wire the VFD to use the
saw switches to turn it on and
off, it¡¯s easy. As for the
brake, not needed with the
VFD, it does the braking.

need overly detailed info at
this time but exploring some
options.
For
a 5.5 hp 3p table saw could
a 10hp rp work or would i
need to go to the next size
which is i think 15hp.
Also
would a vfd work and if so
is there a way to wire it so
the saw switches would work
or is the only way to start
is with the vfd. This saw
would have a brake.
