Which way to connect a 3 phase motor?

dimanche 31 août 2014

I have an old 5hp 3 phase motor and have access to all points of the windings. My question is which way to wire it star or delta?



The motor is rated 400/440V but it doesn't mention star or delta on the nameplate ... but it does mention the current as being 7 Amps MESH (I think it was 7). I think the "MESH" stamped on the nameplate answers the question, but I'm unable to determine what it means.



Any help appreciated.



BTW I have it currently running in star config and it is running (but under no load).
