Motor wiring help

Hi guys,

Having done much reading and research I decided to build a phase converter, of the rotary type.
The problem I have is that when I opened the terminal box for the motor I have to hand, it didn’t look like I was expecting. I.e, not like the pictures or diagrams you see online. Even the numbering isn’t what seems to be the norm.

It is a 2 speed which maybe the reason. I’d like to wire it up to run in the star position giving the higher kw out put. This is only a temporary for the build so that I can get my new mill operational.


Any help with this greatly appreciated.

I’ll try attaching a picture.

Hi,
Given the numbering of the wires, I suspect A1,B1 and C1 to be the Star point.
Then A2/A3 are the tap and end of one ine winding...ergo to change the speed it would be a matter of joining A2/A3 together....etc.
Do you have a foto of the motor data plate?

farmerjoe:
Hi john,

Hopefully picture of motor plate is below.
