If you can find the value of the capacitor, generally marked on the side..
value(uF MF mF etc) and voltage, part number.

The value will indicate what type of motor it is, although it appears to be
a PSC type )permanent split capacitor) motor, and possibly multi-speed (or
dual voltage).

There may be worthwhile info on the motor case.. a tag or diagram-p/n on a
label inside the wiring cover if equipped.

It sounds like an open frame blower motor from a furnace or air handler
which also included an electrostatic air cleaner.. that's likely what the
12kV is for, definitely not needed to operate the motor (should be removed
to prevent any surprise shocks which could result in serious injury).
If the appliance was a home comfort apparatus, you might try posting a
picture on a HVAC forum.

I would cut away the HV module and try to determine if the (top) white lead,
and the (bottom) black lead/AC are the power leads.
There should also be a secure earth ground connection to the case for
testing and use/operation.
Testing should be attempted by a qualified, experienced individual with the
capacitor in place as shown.

Without a motor manufacturer's name or part number, you may not find any
data regarding the other leads (red, yellow).

Hi,

Pulled a fan motor from a large (new) assembly some years ago. The best I
could
do was to take some attached components along with it so I could sort it
later.

The start cap and a High Voltage Module are there as well as the line
cord. The
switching assembly had to be left behind. As it was on the street, I
could not
do any better than I did.

I am scratching my head on how to wire this and want to use it.

Seems like a selector wired to connect the Red, yellow or brown to the ac
input
the HV module has (bottom), and connect the other ac input that is going
to the
black motor wire to the white wire (top side of the HV module) would make
sense.

Supplies full power to the HV and motor start cap.

As noted, the 2 black wires have no ohmic relationship to any of the other
wires
or the motor frame.

I failed to get a reading of the start winding to the other wires so I
have some
homework to do before applying any power.

The cap, line cord (marked AC) and HV module are as it was in the machine.
The 12KV HV output wires are omitted.
Why one AC line went to a black wire (and apparently nowhere else) is a
mystery.
I will undo the plastic covered crimp connector and see if I tore out
another
wire that connected to them, but it looks like there were none.

Comments greatly desired
