- This video will walk you through the standard winding terminal designations, proper wiring connections, and expected winding voltages for a Dual Voltage, 3 Phase, 9 Lead Wye Motor.
My motor showing different connections for low voltage which is 1,7,6 to L1 and 2,8,4 to L2 and 3,9,5 to L3 can you explain it please
Your motor is a Delta connected Dual-Voltage Motor: 3q0ds8402hawyzjwb3qrnh43-wpengine.netdna-ssl.com/wp-content/uploads/2016/05/Screen-Shot-2016-05-16-at-11.10.39-AM.png
Wow! Great video! I can almost skip my classes in school and just watch how you explained it beautifully. Thanks for uploading this.
Nicely done Pete! Your detailed explanations are appreciated. Nice " dj - like" voice too.
I enjoyed your easy to read diagrams and your voice is clear. keep up with all the good videos
This video explained all of my questions and more about 9 lead, 3 phase wiring! Thank you!
Any time. Thanks for the nice comment.
Great job in clarifying that the second and the third diagrams for the parallel wye have that important difference in the neutral points connection. The second one indeed helps in visualizing the connection arrangement.
Thanks for the video and great information provided with the wiring explanations, I was looking for a little "memory refresher" but I ended up learning more with this video. Never stop learning!
I have a onsite assement with Pepsico this afternoon and I truly appreciate the simplicicty of your video, I believe it will help me tremendously.
Thank you!
Excellent. Good luck on the interview Antonio!
This video is truly on point and detailed. I went to my onsite assessment with PepsiCo Yesterday and the part of the assessment was based on a black box test. They require you to connect a 3 phase motor. Only 20% of interviews actually pass the first part of the assessment, and if you cannot connect the wiring for a 3 phase motor in 8 min. the interview is over. Because of this video I completed the task in 4min.
Best comment ever! So glad everything went well. Thanks Antonio
Excellent. In a former job, I used to sometimes change out three phase motors. I always followed the diagram on the inside of the cover plate for the junction box on the motor, bumped the motor to check rotation and swapped two if the rotation was wrong. Now I understand what always seemed like a strange setup for the low voltage, although I had pretty well figured out that it involved putting windings in parallel for the low voltage and in series for the high voltage.
This is new to me. Everything was explained clearly. Thank you, sir.
Wonderful explanation! Looking forward for the next video👌🏻👌🏻
Very clear and precise description. Thank You.
A most superb presentation sir.this is most interesting.I'm a UK spark.we have 6 wire motors as standard.with 230 single phase 440 3 phase.star delta.I have to admit I've never come across these motors before.very very interesting.I've learnt something new .very clear and precise.well done sii.a most butifull video.keep up the great work.
Excellent, detailed explanation; many thanks !!!
Very good explanation.Thank You
Excellent Vedio 👌👌👌👌👌
First one done 😁 in class with drawings on first attempt !!
Sweet!
Many Thanks!
thanks mate! very helpful
Thank helped a lot
Very nice Sir! Give idea about how fill motor Armature coil slot to slot in starter slot?
This is very good. But if given a 3 phase motor how do you sort the nine colored leads out. How do you define the numbers t1-t9 on the colored leads?
Awesome thanks
Thank you sir.
Very nice technic
Can you make a video about how to find how what number the leads when the numbers are missing or worn away thanks peter
This was great
Circle of death ! LOL ty for this !!
Question: I'm going to install a used system 27 Hp bitzer compresor, for ultra freezing, this system was assembly in china, installed originally in Seattle Washington, and I'm goin to install here en Baja Sur Mexico. The evaporator has 4 Chinese motors 3/4 hp 220/ 380 V, and each motor has 8 leads, 6 black lead numbered from 1 to 6 and 2 more Yellow leads. I notes that it were connected to 220 volt 3 face, L1 to leads 1,5 L2 to leads 2,6 and L3 to leads 3,4 The other two yellow lead i don't know exactly where were connected, I'm assuming something for controls. Did you saw this kind of connections before? do you have any idea what the yellow leads are for? there is not information at all in this motor and system, no serial numbers no model numbers only the compresor who was made in Germany. The evap motors only has the voltage, Hp and amperes that's it.
Thank you in advance.
I'm apologize, my English is not the best.
Thank you
Hello, good day. 3 phase asynchronous motor with 6 leads can work as asynchronous generators. Does it apply also on 9 leads?
Greatt video. Question - Why do we create new Y connection point. Is it because the existing Y is not accessible to connect to it.
Yes. Connections 10,11,12 are already connected together from the motor manufacturer
Thanks for sharing this video sir.Do you have also the delta system?Thanks and Godbless
Sorry, not yet. Jim Pytel has a good video here though: ua-cam.com/video/XsL1o4Lm7wg/v-deo.html
Good afternoon. I am currently studying industrial electricity basics. Arround munute 4:20, you mention that in order to reverse the rotation of the motor you just have to switch any two of the incoming conductors. My question is: in the original instalation, how do I know which line is L1, L2 and L3 respectively?
The conductors are colour coded for each phase (colour codes vary with each country), or in the panel, disconnect, etc. the conductors will be connected to terminals with the designation L1 L2 L3. Even if nothing was labelled and you had 3 unmarked conductors, you could connect the motor, turn it on briefly and look at the direction of rotation. If it was in the wrong direction, just interchange any two conductors. If the application does not allow for the motor to turn in the wrong direction, you could use a phase rotation meter (a meter that connects to the 3 incoming lines and tells you whether the motor will turn CW or CCW)
That was really helpful. Thank you.
With a pencil and paper I wrote out all 6 possible linear combinations of the three input lines (123, 132, 213, 231, etc). Then note that they are arranged in a repeating circle, with no defined starting point. So, you can see that of those six possibilities, only two are unique, the rest are rotational variants. So, even if you don't know which one is exactly L1, L2, or L3, there are only two possible ways to order the lines. Swap any two lines and you get the opposite configuration, giving a motor with opposite rotation....
I really need this couldn't read to copy n follow even the print. Feel slapped w nothing
What about line 3 is it the same voltage of 1 & 2
Can I provide 125 v. In each Line ? Please advise
My Canadian Harmonized Level 3 Electrical textbook says to go clockwise on T1,T2,T3....
Do you guys have to purchase the textbook or is it given to you? Do you happen to have a link for this material? In Ontario we haven't changed over from 3 years to 4 years of In-School Training.
Pete Vree British Columbia I purchased the textbook for $140 from my campus book store.
Pete Vree if you have a BCeid account I do have a link you can access.
