I know nothing about controls and motors. I measured 400v at isolator , which then goes to id say is a starter of some sort (pic). I then measured 230v at motor housing. I used martingale gs38 testerWhat controls the motor? .... DOL, VSD, Star/Delta, Soft Start etc etc?
Has it got speed control?
What meter are you using to get your voltage?
What's the nature of this post... is something wrong with the motor or its operation?

Agree totallyNeither do I, that's why I leave it to others!
I measured 230v at all points on motor to earth but nothing between connectionsIf it's supplied by a variable frequency drive there's a good chance your tester won't be able to make sense of the supply at the motor due to the high carrier/switching frequencies.
