Help 3 phase to single?

Question

I just purchased a 1993 Model: 3025 Onsrud Pin Router.

Can you tell me what this means other than it's 3 phase?

12.2 V23AC PH3 H260

I do need to convert 3 phase to single phase and I am more than confused trying to figure what to do or buy. I have read on a companies web site that their product is best because most converters are just used to start 3 phase and there is a lot of loss of power, theirs on the other hand don't loose any power. We're talking big bucks for one of their converters. What do I really need to look for? And where if possible?

Thanks

Chuck

likely its a garbled interpretation by the seller of what printed on the ID plate.

most model 3025's seem to be 5HP 220V 3PH

your options are:

rewire the shop for 3 phase use a rotory converter use a solid state converter (lke a UPS) replace 5HP motor with single phase motor.

i would wait till i inspected the machine to make the decision. if it has been poorly stored it might be best to replace the motor.

like Tim Perry said, It looks like the seller didnt read the name plate correctly and just threw some garbled numbers out there

Looks like it should read...

230/460VAC 3Ph 12.2 / 7A

Dropping one of the 3 phase wires will NOT make this do what you want it to do , but will cause the motor to do what is actually called single Phaseing and more than likely burn a winding up....

2 wires hook em up 3 wires Burn em up 4 wires F**K em up
