Then we noticed the saw blade was going round the wrong way!
The motor is about 1.5hp I would guess looking at the size of it. It was reclaimed from something else and hence the original plate lable is now mostly unreadable.
I am not sure what type of motor it is, but there is no external start capacitor visible. Also when it spins up I could not hear a click from a centrifugal switch (not that this is any guarentee that it does not have one).
So taking the cable entry plate off reveals six connection studs - one of which is earth. The others are arranged thus (the letters are those marked by each stud):
# Z # T
# A # Az
The incoming mains is currently connected to A (Neutral) and Az (Phase)
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.
Sugestions for an alternate wiring pattern to get it spinning in the other direction?
