Hi,
I recently picked up a Boyar Schultz surface grinder which was wired into the shop's 3 phase supply. The machine has a 1 HP motor and hydraulics as well as a coolant pump. Looking at the existing electrical panel, it looks like there's one 3 phase source and a 110 source picked off of a step down transformer. But, I see what looks like two 3 phase contactors so I'm not sure if I would need more than one VFD. Would the hydraulic motion normally be turned on or off separately from the grinding wheel?
I'm also assuming that almost all of the existing components in this panel will go. I'll use the existing switches wired to the VFD for start/stop and I could probably connect the coolant pump to an external 110V plug rather than the transformer.
Here's a picture of the existing panel.
Thanks,
Rob
