Back story about 10 years ago i set up my 9c south bend with a 1.5hp baldor motor and VFD due to a missing counter shaft and it works great! Its all serpentine belt drive with a fixed ratio to give 720 rpms at 60 hz. Giving a full range of speeds with back gear and enough torque.
The VFD is a Teco Vector drive. The motor i picked up at a scrap yard for $20 so it could possibly be bad. I just got caught up on some projects and have some time fix it.
When i hooked it up 10 years ago the motor would not start with no belt on it. It would just grumble and jerk back and forth. But when i put the belt on it runs fine. Comes up to speed and seems to run fine. But about 1 in 10 times i turn it on it acts weird. It will hesitate for a second and then try to accelerate hard to full speed normally causing the belt to slip. If it flip it off and back on it will normally start fine. It has been doing this since it was put together 10 years ago. Not really a problem but ive used it a lot lately and it go me thinking i might have a bad motor and woudl like to test it. It also seems to hum under a heavy load.
If i have a bad phase would the motor start with a VFD?
