Wiring an industrial cabinet for super 7

9 forum posts 4 photos | Hi, I have a single phase Myford Super 7, I did not get a cabinet with it, so I have just bought an industrial style cabinet for it. I think the cabinet is wired for 3 phase. See pics below:
The loose switch in the pictures is the coolant switch.
I have some specific questions: 1, Can anybody confirm this is a panel for a 3 phase motor? 2, Can anybody confirm a rewiring scheme to wire up my single phase motor? 3, The panel has high and low speed, that I believe would require special 2 speed motor, single or 3 phase. Is that true? 4, Are my options limited to ? : 4a, Rewire for single phase 4b, Install an inverter. If so am I correct in thinking I need a three phase motor, as well as an inverter? 4C Any other options?
Thanks in advance Jeff.

![]() 3676 forum posts 82 photos | The coil voltage on the contactor is going to need to be 240v for a single phase panel, it may be simpler to replace the contactor if it is 415v as tracking down a 240 coil is likely to be difficult. It may be possible to unwind some turns from the coil bobbin if you fancy a challenge. The two speed motor would make it likely that the cabinet was for a Trilever ML7. Apart from the contactor issue it should be possible to rewire for single phase. A VFD is almost universally recommended, they have some limitations but the pluses trump the negatives for most people. Mike Edited By Mike Poole on 01/04/2019 20:34:16 |
