The motor has a tag on it. What does it say for voltage and amps?

I agree there is a fair chance the motor is set for 220V, and needs wires swapped around.

that looks like some thing exotic....
does it run, or attempt to start? or does it trip out when power is applied? details if you want the armchair engineers to be able to diagnose anything
not sure what good that would do him if he only has 110V service.
OP might have 220 at his home available and don't even know about it... just like most of the people in the USA here don't realized they have 220V a(ahmm 240V), then again never been there and won't know...

You are right he did say it on post 29... oh there goes that idea ....

You really need at a minimum 8 gauge wire and 50 amp breaker. 6 gauge wire would be better. (copper wire)

I have to agree with above... A 30-amp breaker for a 3HP/3.5HP motor @ 110V is not large enough... You would need *at least* a 40A, and even that might be too small...
I am neither an electrician or an electrical engineer but that sounds like a bad/incorrect capacitor on the motor.
Would the capacitor need to be different because he went with the 120v motor?
Did you make sure it has oil in it? Is there a way to turn it over by hand (with it turned off) for a few revolutions to be sure something isn't locked up mechanically?

Electric motors draw many times the full load amp rating at start-up. If the wiring is too small, the amperage will increase even more because of voltage drop. Increase wire size and breaker rating and all will be fine.

Just looked up the chart on this 3 hp 110 volt draws 37.9 amps start up 4 hp draws 49 amps on startup. So if the motor is 3.5 hp you might barely get by with a 50 amp breaker though I would suggest 60 amps . I can't remember what code says about size of breaker.

according to their website it is 220/50/1 --- 220v

I'm sure with their large group order they were able to spec the custom 110v motor they all needed... Chinese will build things however you want if you want to spend the money.
well on OP's post #68 he had a pic of that motor with a tech plate....
Maybe he can get a clearer pic of it and post it up even if those things are in KW ratings, some one should be able to translate it....
... man hope this doesn't turn into a dud..
this pic....
But I think slkay944 is right their web site have the lowest model is 220/60/1 or 220/50/1 2.2KW for the JYGL-03 / JYXG-03 model All other are 3 phase..

Jvv - I just want to say... some of us, me included, do make a bit of fun about this, because of China, ...But the collective GJ Brain does want to and WILL help you get this done.

From the breaker panel to the plug in receptacle ("Wall socket"... If Any) is I understand what the experienced guys are saying.
And ALSO to the machine.
So, allllll the way breaker to machine.
You tech guys please correct me if I am wrong.

Were going to need a closeup of the motor nameplate. The nameplate on the enclosure as well (if there is one).
Im hoping they didnt send you a 220v compressor either intentionally or by accident. That would be the first step, knowing what you got. Then we can go from there.

From the breaker to the machine. What amperage is your incoming service? I don't think that question has been asked yet.

You shouldn't have to change the capacitor on the motor... Every dual-voltage motor I've used you left the capacitors alone when switching voltage.

Yes, capacitors are not the problem. Unless bad from the factory.
Their website also says they will have after sales support until issue is resolved.... usual turn around is 24 hours .... maybe the OP can email them... as far as the motor... unless it is a special order... 110V is not available as a choice in website..

Where is a picture of the motor data plate?
And you would think that they would be fine, as they are essentially the key product line of the compressor's manufacturer: Wenling Jiayang Capacitor Co, Ltd

Just did the calculations again using the rating off your motor plate. Based on that 45.4 amps draw at 110 volts. I'm not an electrician but have worked in electronics all my life so I'm comfortable using the formulas. Based on the requirements I think you need a 60 amp breaker, anything less will trip on startup.

You said this was a group buy. Is everyone else having the same problems?

What wiring / breaker is he using?
Problem is when you are running undersized wire you are going to get a voltage drop / increase in amps, which if it doesn't trip the breaker it will cause the motor to run hot...
If your breaker panel is in the garage or somewhere with easy access, try a temporary setup with a larger breaker & wire size as has been suggested. If it runs properly then you can run a more permanent setup to where it needs to be.

Looks like 27 Amps on the name plate but I could be wrong. Minimum fuse or breaker size would be 27 x 1.25 = 33.75. (Largest motor in the whole machine).Next common fuse/breaker size is 40 amps. Are there any motors or loads in the compressor like fans or driers? They get added to the total Current/amp draw. The motor can actually be fused at 250% of full load amperage. This is to overcome startup.

Because capacitors are usually rated in DC voltage, and the peak it will see on AC is higher than the nominal line voltage. The nominal AC voltage, in this case 110V, is only the root mean square (RMS) of the peak to ground (or half of peak to peak). A capacitor will be charged at peak, which is about 155V for a 60Hz 110V RMS supply. This one appears to be rated in AC.
ETA: start capacitors can be pretty marginally sized by OEMs as they are not under power for very long.
