I have a shaper table that came with a 9 wire 440v/220v Delta Rockwell motor. I can't seem to get it to work. The motor hums and rotates very slowly when powered. It also appears to be drawing about 27 amps per line.
I have leads 4, 5 and 6 tied together, leads 1 & 7 to one hot line, leads 2 & 6 going to another hot line (out of phase of first hot line) and leads 3 & 9 going to a neutral. I do see 220V across the two hot lines.
I also don't think any of the coils are shorting out to ground. Leads 1 & 4 have 2.4 ohms, leads 2 & 5 have 2.4 ohms, leads 3 & 6 have 2.5 ohms. Lead 7 to leads 8 or 9 have 4.7 ohms.
Any advice if I'm wiring it wrong or the motor is burned out?
Thanks for anyone who's familiar with these motors - Charlie.
