I picked up a 3 phase Baldor motor today at a scrap yard for $30.00 and I thought I dotted all of my "i's" until I read the VOLTS.
Here is what the side plate says:
Cat No- M17
SPEC.- 37BO1Z37
FRAME- 215T
HP- 10
VOLTS- 200
RPM- 1725
HZ- 60
SER.F.- 115
PHASE- 3
CLASS- B
DES- B
CODE- J
NOM. EFF.- 85.5%
P.F.- 76%
RATINGS- 400 AMB-CONT
Weight- 105lbs
The motor only has three wires coming out of it and each have a definite identifier on each one. They are numbered 1,2 and 3.
Sadly the motor seemed to have been pulled originally with care and then they must have decided to scrap it. I still need to take the connector that joined it to the pump shaft (they cut it off with a torch) but I expect to see a complete motor spindle there. The box mounted on the motor was broken off as well.
Here are my questions:
1. Is the 200v going to be a problem? I need to make a 3 phase rotary converter to power a 7.5hp motor on a Grizzly Saw and possibly a future milling machine and metal lathe.
2. I understand that the wires labeled 1,2 and 3 are for each phase or leg but where do you connect the other necessary wires to make the motor run?
3. Does it matter what RPM the future tool will have since this is a 1725 RPM motor? I know the 7.5hp motor is something like 3450 RPM or so.
4. Does a oil filled capacitor rated at 370v work or do they need to be rated at 480v? Can I get by with lower voltages on the capacitor like anything rated 240v and up? Realistically I would think that a rating of 120v and up would work only because each leg (I thought) is coming is as approximately 120v.
My plan was to start with the basics with a Cap on L1-L3 and L2-L3 (L1 and L2 being the workshops 240 Volt Input and L3 being my generated 3rd phase)
Should the motor work okay with my standard home type electricity being rated at 200v?
Is there any special formula to use since the motor is rated at the 200v for the capacitors balance for the final 3 phase output?

Thanks!
