I was wondering on HP rating because I know when sizing a transformer , the Kilowatts should be atleast 40% more than the max wattage the tool will pull. So was wondering if the same applied to VFDs.
So a 1.5 HP VFD should be plenty fine ?
Thermite and others:
Do all VFDs also provide step-up voltage ? If I am reading the replies right, we don't even need a transformer, can just use a VFD?
Oh and by the way, this machine is not mine, it is in our Tech School (Milwaukee Area Technical College). I am in the Autobody program, where we plan to use the machine for sheetmetal forming. I am just helping out the instructor in getting information to get it up and running and sourcing various dies. Researching inexpensive and least hassle ways to get it running, then will pass on the info to the instructor who will suggest it to the school's electrician.
The school does have 3-phase 220-240 and 600v 3 phase but the outlets are not located near where the machine is going to be, and 3 phase extension cords are a no-no. There is a 220-240 volt single phase outlet near the machine, which is what we are going to use.
So what brands would you go for? Needs to be a brand name known for safety and reliability.
ABB , Allen-Bradley, Toshiba, Hitachi, Siemens, Yaskawa ??
What do you all think of these 2 VFDs:
Yaskawa . 1.5 hp . 200-240 volt single phase input . Output 200-240v 3-phase. 6amps max load.
Yaskawa CIMR-JUBA0006BAA, 1.5 HP, 200-240V, VFD
ABB 1.5 hp. 208-240volts single phase input. Output: 240v 3-phase. 6.7amps
