Havent had the time to mess with it the past couple of days but as luck would have it i found a single phase 5hp in my area that someone is trying to trade for a three phase. I was trying to take the cheap route with my compressor. Mine is probably from the 30s lol. Its an old Gilbarco 60...

Motors not connected to the vfd right now. Testing the vfd itself. Compressor is half assembled at the moment. Belts and flex hoses show up tomorrow.

Checking the vfd info input current is 25a. Not sure what im pulling right now need to pick up a clamp ammeter tomorrow. Just have a multimeter here.

Its getting the fault as soon as the run button is pushed.

Currently troubleshooting a Vevor A2-8055 VFD. Its for an air compressor im building. I have a 5hp 3 phase motor wired for 220 that is inverter ready. With the motor leads wired to the vfd i was receiving an OC-U fault which is acceleration overcurrent. With leads disconnected i get OC-R which...

Guessing parts will get here by next week. Ill post some pics once the build gets going.

Also mine is going to run off a vfd due to the motor being 3 phase. The vfd would have been able to power the fan. The few of these coolers ive seen used they werent using a fan. Ill add fans at some point depending where the outlet temp is at.

I went with a cooler from compressor-world. Its the plate and fin one rated for 5-7.5hp compressors with the 3/4” npt fittings. I had to order a few other parts anyways. This “cheap” compressor keeps getting more expensive lol. It went from a rusted out 3hp 60 gallon to a 5hp 120 gallon. Would...

Very nice setup. I went with a blade guard mounted cooler. Dont have a blade guard at the moment but i can slap a mount together for now. I see you are using flex hoses, im going to go with those instead of hard tubing. While im waiting on parts to show up im going to tear the pump down...

Also if you take the vfd route make sure you factor in the inrush current of the motor (people saying not to use it probably didnt size the vfd for it). Theres calculators online to determine it. Just put in info from your motors info plate. The calculator will show you the motor start amperage...

The compressor has nothing to do with it it only deals with the motor. Its just a case of knowing how to program it and adjusting the frequency until the motor is turning at the right speed. It can be setup to operate as a soft start where it will come up to speed over a set amount of time. I...

Ill drop this here since it seems relevant to the topic at hand. I was just in the garage with my 5 year old son who is autistic. He cant talk socially or really tell you what he wants but he understands how machinery works without ever seeing it before. I have the 325 sitting on the floor of...

Thats why i said it probably wouldnt matter in an earlier post. Sorry about the long posts with no seperation. In person i talk just like those posts look lol. I have ADHD and my medication makes me a bit manic (even though its supposed to do the opposite) so i have an excess of energy. It...

No problem. If youre working with a 3ph motor thats 10hp or larger it would be better to have a phase convertor. This is for my home garage so 5hp is plenty. I have a couple of cars i need to paint but ill mainly be using it for air tools and a vapor blast cabinet build. Have some wheels and car...
