NINE LEAD WYE MOTOR CONNECTIONS: How to make the high voltage AND low voltage connections

Nine lead wye motor connections demystified! This video is the first in a 2 part mini-series on how to connect 3 phase motors. In this episode, we walk through the wye motor connections for both high and low voltage connections. What motors do you commonly see in the field? Drop a comment below!

Thanks for you help man, your a great teacher

[@vairammuthu4868]

Super and simply understand this video thank you sir

[@bigmikeh5827]

Great technique. I’ll share this with my apprentices

[@sajicherian539]

Easy explanation very good class appreciate you

[@solarstorm50]

Thank you! A LONG time ago (40 yrs ago) I was a 4th yr apprentice. I recently bought a motor and VFD for my shop. For the life of me I could not remember how to do this! If only my instructors back then had taught like this.

Thanks for the video! I have basic knowledge and trying to get my 3phase lathe connected to a vfd. My 9wire motor low voltage setting is wye like this one. My question is about 4,5,6. After wiring L1,L2,L3, do I just leave 4,5,6 capped together inside ? Also if the motor has no ground would it be acceptable to wire my own ground to the chassis?

Hi , I like your video . Thanks Sohail from MI State

Thanks Sohail!

How does a guy learn to crawl at retirement age? By-passing a load? Jumping points of connections? Hmm, just when I thought I had the ball understood, somebody dug up the goal post. Seriously though, this info is a much help for basic understanding I had yet to learn. Thanks.

[@user-dn8ce9fo8l]

Yes more y connections could u explain the euro drive connections see alot of those

[@Trendd_official1]

Very good its simple

Hello, I have a 3 phase 9 lead dual voltage 230/460 motor... I watch your video and wired it for low voltage. my question is I only have single phase supply.. can i run this motor on 2 hot and a neutral. and if the answer is yes which one of the lines do i connect the neutral. L1,L2.or L3

[@manuellastrollo2168]

why is that the book i read it was done clockwise. what's the difference sir? the Author of my book is Robert Rosenberg

[@jaimeroque4163]

Me gusta tu explicacion.

I have a wye motor with 9 leads but I need a delta connection. The motor is 5 HP but is to be wired to a rotary converter and I will pull only 2HP out of it for a surface grinder. Since 3 coils are connected at one end internally in the motor I was thinking I will leave these 3 coils unconnected. Using your diagram I will connect 1-6 ,2-4, 3-5 forming a delta and not use the other 3 coils. Since I'm using only one set of coils of the two I can put in parallel for low voltage connection I will not be able to pull 5HP equivalent since the impedance of a single coil is half as opposed to two coils. This means the maximum current in the single coil at the same applied voltage will be half of the two coils in parallel and the total power will be 1/4 of 5HP. I can also pull a second low voltage 3 phase out of the star connection since the stator will work as a transformer as the motor spins. Does anybody see an issue with the logic above?

thank yoou very much

I see a lot of dual voltage rated motors that are 230/460V. But I only have 208V or 480V available to run. So what am I supposed to do? Run the circuit through a general purpose xfmr?

[@reeffylord6924]

What you call a phantom connection. Wouldn't you consider that the 0V or ground as a further visual of what's being connected across the windings.

[@jerrylynnparks6179]

You have L1 L2 L3 which is ground?

[@juanjose312000]

What could happen if I connect low voltage (230V) to a single wye (high voltage configuration) ?

[@skatewithvanz]

Youll get more resistance so youll have less power

[@MichaelHoyt-MulticraftTech]

WHY DID THEY CHANGE THE NAME FROM STAR TO WYE? WHAT WAS THE POINT OF THAT ? I'M OLD SCHOOL.

[@CatnamedMittens]

It's shaped like a wye.

[@NotRKelly.]

Boop and boop and boop lol

[@mix_cdawg0978]

Not 100% accurate for the low voltage explanation because you aren’t connecting the 4/5/6 connection and the 10/11/12. It is actually 2 windings in parallel with 2 windings. Not each winding paralleled. But good enough for the beginner.
