Sorry for the misinformation, I did have the motor wired incorrectly.And the lathe is a HB 575.10 HP motor runs fine now.Could you provide a schematic to wire the 10HP in correctly? Thanks for being so patient.Idler motor is
10 HP( I thought is was 15)
1755 rpm
220/460
27/14.5 amps
SF 1.15
3 phase
Idler motor
10Hp
1760rpm
230/460
24.4/12.2 amps
SF 1.15
3 ph
Makes more sense all-around, now.
RPC side isn't complicated. Wotever the original 10 HP had that "worked OK" is left alone.
I would put a tach onto that and confirm the RPM, though.
A 3-P capable contactor with appropriate current rating is needed to drop the three legs of the supplementary idler motor onto its same-same leg outputs of the primary. I favour 60A 3-P Mercury displacement units for that. No external arcs, self-renewing contact "surfaces". "This end UP" matters on those!
The HBX-360-BC had a full schematic glued to the inside of the electrical cabinet door.
If your one has gone walkabout, there is plenty of Cazeneuve info online. Possibly the best documented lathes as have ever existed, the Cazeneuves are, and not JUST in French. They have a short ton of manuals, schematics, and diagrams published plus "factory" videos on the newer ones, and plenty of user or dealer videos on the older ones.
Motor re-config 2XX VAC / 4XX VAC, BTW is not done at the motor peckerhead on the 360. It doesn't even HAVE one, close-coupled right-angle rubber boots, rather.
All wires are instead carried to the electrical cabinet for easy re-config on DIN rail terminal blocks there.
Neat idea, save that as usual, DIN-rail blocks are such overly fragile shite I'm re-doing my one with stouter old-skewl goods.
YMMV, but rocket insemination, it is not.
