Sorry thought I'd added photos first time
 
It was a fairly trivial exercise using Google to find schematics and installation instructions for those. Do that.
 
Have googled it no schematics or installation instruction on the net.
 
Do a search on “IEC single phase motor connections”. You might find something useful, but to be honest, that looks to have something proprietary to it because there are more wires than are typically needed.

There may be internal limit switches, but the OP has not given enough details to work with, despite the pretty pictures.

It may be a wasted winding motor.
One start winding and two run windings, one used for forward and the other used for reverse.
Or it may be something else.
Seven leads is not common.

Curious the Green and red wires are much larger than the black.

The striped are the start switch carried out of the motor.


Why are you showing the drum switch? Did actually come with that motor?

Hi Keith.
I am guessing;
Green are the start winding.
Red is a common run winding.
The black wires are forward or reverse. (only one used at a time, hence "wasted winding")
We can't be sure without some testing.
About all that the picture of the drum switch shows is that it is green with a black handle.
Comments gladly accepted.

How would you wire the motor
Does the switch transfer connection to fatward or reverse windings or does it stay connected all the time ?
 
Merry Christmas.
Really, I can think of at least three ways to connect that motor with the information given.
There may be one or two run windings.
If there are two run windings they may be connected in parallel or in series.
or
It may be a wasted winding scheme where only one of two windings is used at one time.
You may have to identify polarity as well as continuity.
There may be a possible connection that I have not thought of.
A mistake will lead to motor overload or burnout.
Please take the motor to a motor shop.
Keith may be willing to take the time to walk you through a process of identifying the connections.
It's not that I can't identify the windings.
I don't want the responsibility of a mistake and I frankly don't want to spend the time.
I was once faced with a Dahlander motor with all the identification lost from the leads.
I sorted that one out.
Could I do that over the phone or over the I-net?
Never.
