Running a 1/4 hp 220 VAC condenser fan motor on 110 VAC

Yes, about as dumb as the people who design and make the motors;
Reliance!

I guess that you can't trust their words either.

"At the same time torque is being produced, the conductors are moving
in a magnetic field and generating a voltage. This voltage is in
opposition to the voltage that causes current flow through the
conductor and is referred to as a countervoltage or back EMF. The value

of current flowing through the armature is dependent upon the
DIFFERENCE between the applied voltage and the countervoltage."

The countervoltage or back EMF is opposite the applied voltage and it
therefore

"bucks" or reduces it. For example: If the applied voltage is 220
VAC and the back

EMF is 70 VAC, the motor appear to see only 150 VAC.

The result is the equivalent of increasing the total impedence and thus

reduces the current that

would flow if there was no EMF.

This is why an AC motor must spin to avoid overheating.

An automatic thermal overload protector is usually built into HVAC fan
motors.

Or, if you desire, you can always add a correctly chosen fuse to
protect your AC motor.

Bubba,

If you had another brain it would be lonesome.

and argueing with you would be like fighting a sword fight and YOU
with no sword.
Honestly, Your ramblings are worse than stormy and Todd all rolled
together.
Climb back up the skylight and shut it on your way out.

Thanks Bubba that is why I get paid to travel up to 5 hours

Thats sweet. Too bad they didnt tell you that they send you out on 5
hr drives each day to get you out of everyone else's hair.
You drive a lot, I bet.
By the way..............I wouldnt be bragging about $135. In reality,
that aint shit. You have 5 hrs at $135 hr and a GOOD service tech
running the residential circuit can drag that in in an hour.
