12 lead 3 phase motor continuity
12 lead 3 phase motor continuity
(OP)
I have a 460 volt 3 phase motor with 12 leads. 4to6, 5to8 & 6to9. When I do a continuity check with all the other leads unhooked I get continuity across 1 & 10. Nothing on the other leads. Is this a good reading?





RE: 12 lead 3 phase motor continuity
There are other 12 lead motors. Wye-Delta can be 12 lead and, if I'm not mistaken, some part-winding motors are also 12 lead.

Is there a typo in your first post? You have 4-6, but 4-7 is a standard connection and in sequence with 5-8 and 6-9.

Yes correct, my error. It is 4-7. Thanks for correcting that. We megged out the motor today and hooked it up. It works fine.
