A brief overview of how to wire a three phase motor, and what the labeling on the side of a motor means. if you guys are interested in picking up your own copy of the Ugly’s electrical reference guide, check out the link below.

Very VERY helpful - Didn’t know there was a standard, you made me understand because unlike others you actually EXPLAINED there is a NEMA standard -

thanks for the video, around 25 years ago i was a maint forman at a huge bakery and we used to have to run power to a lot of large equipment, large motors up to 75 hp, but it’s been along time im a pipefitter/sprinklerfitter by trade the last 25 years so i forgot more than i remember, i recently bought milling machine and it has a 480v 3 phase induction motor but my shop has a single phase service so i bought a single to 3 phase converter and am wiring it up for 220v the only other option i have is bringing in a 3 phase service or buying an 8
$800 110v motor your video helped me a great deal thank you so much!

Hay another great video Dan. People that have never went into the trades don't understand a lot of things especially standards & codes they are there for many reasons safety being #1 reason. I've been doing industrial maintenance for about 30 years and your spot on about the uglys being the bible it's saved my a$$ quite a few times. Lol

Very clear and concise. Great video.

Now, to connect a 6 terminal switch with 12/3(2 positive, 1 neutral) #12 wire.

That was so clean thank you bro that helps at lot

[jaybitz]

Thanks for the explanation bro! Very detailed.. I graduated from automation and controls and I remember hearing about these terms

[michaelfarfan]

Great info will definitely be looking for that ugly book

[Jcestanley]

dan dude....yup, when I saw your name thats what it became dan dude...Ive been in electrical for a long time power generation to be exact and I have heard the term peckerhead over and over and to be honest I never knew what that was. For me its simply a junction box but damn dan dude. I just learned something today. About to do a ton of checkouts in a new chemical plant so im brushing up on my wiring. Thanks for the vid man!

[TheCompton]

Great video. Great info. Thank you!!!! ⚡️⚡️⚡️

Thanks Dan. The other day I changed a electric tip dresser motor and the part numbers were different the r/min on the original were motor was 281 the new motor was 1655. My supervisors wanted me to install the new motor anyways. I installed it and it has been running for now. Will this cause any issues going forward?

Per NEMA recommendation, swap Phases A & C.
Thanks for the video.

You should of also said how to connect the high voltage side

[IRLArgentino]

Something that just blew my mind is that I can spin a pump and it's probably designed to be self tightening so now I know that if I hear the impeller surging, I can switch directions and make it function properly. I've yet to see a pump dictate which way you should spin it but now I know.

How would you go about finding which wires are wich if the labels have worn off of the motor/wires?

[Freetheworldnow]

You should have included the wire color chart as well in this video.

[Matthewmiller]

ok so what im getting from this video is i can connect any of the 3 lines red, white, black to the supply lines on the motor and it will work? There is no certain color to certain line on the motor? Obviously green for ground but any of the other 3 i can hook up and it should work? If i want to reverse the rotation all i do is change any of the 2 supply lines and it will chance rotation?

[brianberson]

Dan do u have a video on checking to see if motor bad. Check boltwges and resistance

[jaysmokey]

Not good if I have to keep re-learning this! Especially if it's pretty simple and hard to forget... I put my brown orange yellow with all three wires i.e. brown with 1, 7, and 4, but caught my error...

I changed rotation in a snow making pedestal a month or two back. Next day i was with a different journeyman, he asked me what I did the day before, so I told him i changed the rotation on a pedestal. He asked me what colors I changed, I said I did the brown and the orange (honestly can't remember now??) but he was like "nooo dude you have to change the orange and yellow" I was like bro it doesn't matter??

Question, I’ve got a motor very similar to the one in the video except the HP is 2.0 on mine. The rpm rating is 1410 but I’m only getting about 600 rpm out of the motor controlled by a VFD. I’m receiving the proper voltage as far as I know and I’ve got the motor wired exactly according to the schematic for “low voltage” at 230V coming in. Any tips?

[carlosaranda]

I think the high voltage is just wire nut 6 and 9 together then wire nut 5 and 8 together then wire nut 4 and seven together for a total of 3 wire nuts then hook up your three phases by choosing which one to hook up to which line
