Default Motor running the wrong way

In addition there are also wires that emerge from the motor body and
connect to the terminals:

A Red and Black (+ mains in Neutral)
Az Red and Red/Blue linear stripe (+ mains in phase)
S 2 of Red/Green radial stripe
Z Black and 2 of Red/Green radial stripe
T Red/Green radial stripe and White

The red and black wires have a little slack in them and look as if they
could be repositioned to alternative connection points.


Hmm, I've not seen one like that before. Sometimes there's a wiring
diagram on the rating plate or inside the terminal box. Any
manufacturer's name?

Failing that I'd be inclined to disconnect everything (having first
carefully noted ...) and sit down with an ohmmeter and identify which
pairs are the ends of individual coils. You seem to have 11 'ends' - so
there must be at least one tapped winding or double lead-out (possibly
before and after a thermal fuse or PTC device at the end of one winding,
if it's modern enough to have such things).

Essentially/usually there will be two windings (possibly made up of
multiple coils in series) across the mains - one permanently and one via
the centrifugal switch and/or series capacitor. If you reverse either
of the two it should run in the other direction. (HTH, IME, YMMV.)
