AT1 single phase to 3 phase VFD

[@larryvergon6740]

Many years ago when I was employed in the industrial machinery manufacturing industry, we used ring terminals on the motor leads and the wires to the motor. The connections were then bolted (machine screws, lock washers, and nuts) and taped. Less chance of losing a wire nut and shorting out a power wire, saving the wire ends from damage if there were multiple wiring changes, and easier connection changes (we always switched the connections at the motor to change the rotation). Now, after spending later years in the aerospace industry, I would use self-locking nuts WITH a lockwasher (to maintain tension on the joint during thermal cycling) and still taping the connection or shrink sleeving.

[@RockingJOffroad]

Harold, that motor sounds like it needs bearings. Be sure to mount the VFD far enough away from the work to keep metal particles out of the cooling slots. I learned this the hard way!

[@AmateurRedneckWorkshop]

The motor is supposed to be new and it does look like it. I think the grease may have lumped up in the bearings. Thanks for stopping by.

[@TheArsonsmith4242]

Great video and overview. I reached the same conclusion and it's why I put together as much info as I could for my clausing and bridgeport. Now I've upgraded to a 30hp rotary to run the whole shop.

[@AmateurRedneckWorkshop]

That is pretty fancy. Thanks for stopping by.

Thanks Arsonsmith.

[@dannywilsher4165]

Good timing. I just got another lathe and it has a 3 phase motor on it. I was going to do some research to see what was the best route to go but it seems you have already done the leg work. Thanks Mr. Harold!!!

Here I got one of those VFD, not yet installed... Good thing with 3 phase motors, you'll get more torque than a single phase unit for the same HP, it's just that in your situation the speed is gonna be half due to the nature of the motor, there should be plenty of power from that 1 HP 3 phases motor. Don't worry about the order of the 3 wires, the direction change in 3 phases motors is the relation between phases, this is done either physically by inverting any 2 wires or electronically with the controller, same result... No need for capacitors or centrifugal switches to start in the right direction, in most cases, unless you toasted the windings, the only maintenance you'll ever do on a 3 phase motor is clean and change bearings. Another advantage of a 3 phases motor is that it produces less vibrations, due to a more constant torque, great on machines like surface grinders where any variation is reflected on the final result. At lower frequencies you don't get much torque, though... The next challenge at the range may be to shoot viruses, start looking for better glasses, those buggers are real small and hard to get... 😎👍

3 PH MOTORS ARE GREAT WHEN USING 3 PH POWER NOT A CONVERTER. THE MOTOR RUNS ON ONLY TWO LEGS

[@EverettsWorkshop]

Haven't messed much with 3-phase motors in my shop, just single phase stuff so I'm no expert, but the motor runs and the magic smoke is still contained so looks good to me!

[@AmateurRedneckWorkshop]

Yes it has been working fine for a while now. Thanks for stopping by.

[@WeedWorxs]

Great video. I purchased the AT1 from MySweety ($100) to use on a Baldor 3hp 230v 3 phase 60Hrz 8 amp motor. The specifications of the AT1 stated it would handle this size motor however, that was not the case. The VFD worked once but fried the capacitor due to the start up and variable torque needed during operation of running a 48" metal fan. If you're looking to run a "Heavy-Duty" motor, I would advise using a VFD that has oversized capacitors. They'll cost you more upfront but they'll last a lot longer giving you more bang for your buck in the long run.

[@AmateurRedneckWorkshop]

I think it is good practice to purchase items like this that are about twice the rating of the intended load. Thanks for stopping by.

[@Xynudu]

Very interesting video Harold. Nice quiet inverter. Some of them squeal like a stuck pig. Sounds like something is rubbing in the motor or maybe the microphone makes it sound that way. Cheers Rob

Hi Harold, nice video. I have a question. Is it better using a 220V delta configuration (XSY-AT1 as in this case) for tool machines i.e. a lathe or a 380V star configuration (XSY-AT4) ?

[@jotasgasco]

Just got this VFD, was testing it for a couple of minutes until it suddenly wouldn´t turn on, just said Error1 when pushed the RUN button, that error means overcurrent,/short circuit protection, i´ve dissasembled it and nothing is shortcircuited, used a oscilloscope probe to troubleshoot but it just didn,t show anything anywhere, its like the vfd just displayed the message witouth trying to do anything first. Any ideas?

[@AmateurRedneckWorkshop]

I get this error but I just press the stop button and it goes away until the next time I power it up. Thanks for stopping by.

[@jagboy69]

Screw phase converters, VFD is the way to go for the small garage shop. I have one of these exact same vfds... Got it from china for 79bucks. That thing is a diamond! I had it on my 2hp bridgeport and today pulled it off and stuck it on my new lathe. My lathe has a 2 speed motor and with some help, I got BOTH speeds controlled by my vfd! Ordered another one of these today for my mill. The instructions kinda suck, but there is a shit ton of YT videos on this unit. On my mill, I still use the original barrel switch. Just hook the motor directly to the VFD, then I used x3 and X4 connected to the barrel switch. My mill is variable speed already, so the VFD gets set to 60hz and I never even touch it. Same with the lathe. I like things original and hate screwing with the front of the vfd if I don't have to.

[@mharden9134]

hi just got an AT1 to run 2hp 3p motor I confused as I had plan to hook the input to a 220 v dryer/oven receptacle is this correct? or is each leg 220v

[@AmateurRedneckWorkshop]

You are making the right connection. Each leg is 120 volts from the 220 outlet. If it is a 3 prong receptacle it will have two hot wires and one ground. See this for help; www.askmediy.com/220-volt-plugs-receptacles-configurations/ I noticed that on my AT1 when you plug it in it shows an error. Just press the stop button to clear the error and then it runs as it should. Thanks for stopping by.

[@mharden9134]

Thanks that helps me. One more question...One comment mentioned adding a ground to motor...If I add a ground from the motor would it need to be connected back to ground on VFD....Thanks your vedio has been a great help!

[@AmateurRedneckWorkshop]

@@mharden9134 I was not able to leave the ground connected between the motor and the AT1 due to it causing multiple problems and right now I do not remember what they were. I think I am not qualified to say what to do in this case. If you search youtube you will find lots of folks hooking up a VFD so give them a look. I never settle on just one source of information on youtube. Some are completely right and some are completely wrong and some are mostly right while others are mostly wrong. It is a difficult job of sorting the chaff from the grain.

[@mharden9134]

Thanks again got it all hooked up and mounted on my mill. Worked out great...I didnt try the ground from motor to vfd...I have 9 wire motor not sure if thats makes any difference...Thanks again

No magic smoke, means you got it right. vfds are great, every motor should have one.

[@jonrbryan]

Did you leave out the part where you entered the motor nameplate parameters into the VFD? As others have commented, that motor sounds terrible, like the fan is bent and rubbing inside the shroud. If it doesn't have a fan then it sounds REALLY terrible :).

[@AmateurRedneckWorkshop]

I figure it was grease lumped up in one spot in the bearings as it has become quiet with use. I have modified some of the settings in the VFD my first concern was to get it working. Thanks for stopping by.

[@AmateurRedneckWorkshop]

It gets quieter each time I have run it. I think the thing has set still for so long the bearing grease wound up in one place. Thanks for stopping by.

[@lindsaybrown7357]

G'day Mate With the VFD, you can usually run the motor a bit overspeed (greater than 60Hz) providing the motor is balanced and has good bearings. However if you do run it overspeed, it may lack torque.

[@AmateurRedneckWorkshop]

So far it is doing the job at regular speeds so I will probably not mess with it a lot. Thanks for stopping by.

[@lindsaybrown7357]

@@AmateurRedneckWorkshop No worries. As someone else mentioned, make sure you earth or ground the motor. This is always a standing requirement but with VFD connected motors and due to the DC switching voltages, you can get capacitive voltages charging up on the frame and shaft of the motor.

Harold, your motor is not grounded. You should have used a 4 conductor cord. It's not good to run an ungrounded motor, especially on a VFD.

[@dawa8746]

@HouseMade (kzbin.info/www/bejne/iH-lYYqlr6ugepY) uses a 4 conductor 16 AWG from VFD to motor with VFD Output U-V-W = Red-Black-White and Green to motor ground nut and common ground on the VFD. You write you had to swap White and Black on the output to get the motor to turn?

You know I totally forgot about that. The factory setup is adequate for my use so I only changed a couple of small things like the ramp up time. I will insert a link to a video that shows a procedure that is almost the exact same as the one for the AT1. The AT1 comes with a pamphlet of very few pages that show all of the parameters and what the settings are limited to.
