I purchased a B&S #2 surface grinder and a few other machines from a facility that was closed down and the person liquidating the stuff really had no idea about anything which worked out well for me price wise. The grinder was hard wired and I had to disconnect it from live power. It was a 4 wire connection so it was simple to clip and cap the leads one at a time. I never checked the voltage and just assumed it was 230v 3 phase with ground wire as it came up from a pipe in the floor and no transformers anywhere in site.
I started to clean up the grinder and wiped down the spindle motor. The nameplate reads 110V 60 hz 1 hp but the phase info is damaged and unreadable. I opened the motor cover and count 3 wires feeding into the motor which leads me to believe its 3 phase single voltage. No capacitor on this motor.
There is a second motor inside the cabinet for the table but I could not see the plate without a small mirror and some poking around. I will try to tackle that next week
My work place is 230 v 3 phase. I cant go back to the old place to verify what voltage the grinder was connected to or if there was a transformer in the electric path.
I have never seen a 110v 3 phase and like to explore my options to run the machine. I don't think its practical to replace the motors.
1) Will a static phase converter work with a 110 v input single phase and give me 3 phase output at 110V?
2) Can I use a vfd like a teco and program the output voltage to be capped at 110v?
3) Is there a transformer I can use to drop the voltage?
