Had good results with tec.Thanks for that Eddie49 makes sense.
so the resistance of each winding is not exactly the same and to me seems high at +10 ohms.
Here’s the motor plate View attachment 201531
0.9kw so not a biggy and 1400rpm.
I’m thinking start the hunt for a replacement.
Anyone think it’s worth checking/doing anything else before ?
Thanks for all the help.

Ok so pulled it out of the lathe and disconnected from the inverter I think that was throwing results but I still think I have a problem each phase is reading between 10.3 and 10.5 ohms that seems high?

If you go sp you lose speed control ramp up/down braking lower start up surgethis is possibly not a relevant observation but if your considering changing the motor would you not just get a single phase motor as your running on single phase . or i guess the control system needs 3 phase supply anyway?
