Does anyone know how to reverse the rotation of an AC motor?

Yup.

Mind you there are many variations of such that cannot be easily changed.
You would be best informed if you were to specify the motor. Many can be
changed by transposing the leads of either the start or run windings.

several people do.

which sort of AC motor?

Simple swap two phase wires, e.g. L1 and L2

Motor make/model?

Often times, swapping the start winding polarity will do the trick.
Some A/C motors can't be reversed.

 

[Jon]

The specs to the motor I need to reverse are,

A. O. Smith Electric Motor
Mod. F48SH6MA4
RPM 1050
Volts 230
Amps 2.8
Ph 1
Hz 60
Cap 7.5 mfd 370VAC
Rot CCWLE
Ser 8F94
2-speed

I need the motor to rotate clockwise facing the shaft. How do I rewire the
motor for this?

Take a meter, and with the wires disconnected, but well labeled...

From the wire that goes to the starting capacitor, find it's mate (the
other end of the winding).

Swap the locatiosn of these two wires, so that other end of the
winding goes to teh starting capacitor) and the end that was on the
capacitor goes to the original location.

shaded pole motors can be reversed by flipping the stator over (180 degree rotation
about an axis perpendicular to the shaft)

this motor won't come apart. what's a stator? do you mean the armature?

two identical wires go to the capacitor. which one do you mean?

[Jon]

the rotation of the motor is designated as CCWLE (Counter-Clock Wise LE)
What does "LE" stand for? If it means Lead End where the wires are, it
already rotates in the right direction (Clock Wise Shaft End)

does anybody know?

A stator is fixed, the outside (usually) part. The aramature is the
part with shaft on it, which does move (rotate).

ccwle means counter-clockwise lead end, which means the motor already turns
in the direction I want.

thank all of you for your help. someday if I need to reverse motor
direction now I have some ideas.

JFGI. TFD agrees with your guess.

snip....

The capacitor is in series with one of the motor windings. The other end of
that winding goes to the power line (mains). The capacitor terminal not
connected to the motor winding goes to the other power line terminal. Find
the two wires, one to the capacitor, the other to the power line from this
motor winding and reverse them. Do not reverse any other wires. An ohmmeter
can help you isolate which wires connect to the winding in question.
