Managed to get the SAIMP mill situated where I want in the garage finally and Hooked up the VFD and had the motor spinning as expected on the bench.
Earlier today I went to reinstall the motor on the head and get the pulley setup etc. after getting it hooked up and the belt on, the motor wouldnt spin regardless of frequency. I pulled the motor back off and bench tested it. With no load on it, the motor seemingly responds as expected related to the frequency. I tried grabbing the shaft from a standstill and powered it up and was able to hold the shaft still with almost zero effort. I understand the motor may lack torque at lower frequencies but this seems like a real issue. Im wondering if the motor is bad since I never ran it before to test it. Or is my cheap eBay VFD bad? Or am I using the VFD wrong and there is some setting I dont know about that needs adjusting? The motor is labeled 1hp 1750rpm 3 phase. My VFD is powered by a 20amp 220v single phase line, outputting (hopefully) 220v 3 phase.
I have worked as an electrician many years ago for several years but admittedly never really did much with 3 phase, so my knowledge on that subject is just what Ive learned online. My understanding is it doesnt matter what phase is wired to what wire on the motor, but that doesnt mean Im correct lol. Or perhaps there is a setting in the VFD that needs to be changed. Im leaning toward the motor simply being weak/worn. Any advice is appreciated
