I'm currently reading a textbook on electromechanical instruments--as a complete newby who's also having to teach himself the math as he goes along just to try and comprehend what I'm seeing at all. A few pages from where I'm presently at, I've seen the diagrams for delta and star configurations. Point being . . . .this video--and others you made--is really helping me out! Thanks!

Very interesting so thank you for this. It would be interesting to relate this back to the usage for each configuration - I assume delta is used for higher horsepower motors but where does the cutover occur? Cheers

I'm a amateur when it comes to electricity, learned so much.

I used to teach a class on this subject. It was very hard to keep students engaged, as the information is somewhat dry. Having physical examples is the key to learning this subject.

Do you always need 2 sets of coils per phase across from each other (like in your video)? Or would it be possible to use only one coil per phase (so the current enters the coil in U1 and directly goes to U2 at the end of the coil)?

We don't have terminal boards inside the connection box on three phsse motors in America, just nine wires brought out from the internal part of the motor into the connection box located on the motor external. All nine wires hang individually loose within the connection box and are NOT connected when bought from the motor vendor. Six of the nine wires have their own number designation attached to them. The designation ranges from the number 4 thru the number 9. Each of the remaining three wires have their own designation as well. Those designations are T1, T2, and T3. Sometimes T1, T2, and T3 may just be labeled as 1, 2, and 3, not having the letter "T" attached. Again, the nine wires are connected in the field, inside of whatever piece of equipment/system of which they are a part. Three phase motors are built as multi-voltage motors in America. The two voltages are 230 volts 3 phase and 460 volts three phase. How the nine wires are connected is dictated by which voltage listed above is going to be applied to the motor AND whether the connections will be configured as Delta or Wye (Star). The connections within the motor connection box are all made using wire nuts and approved electrical tape, NO terminal boards. Also, the connection box is informally referred to as a "peckerhead" which is just jargon used in the skilled trades.

How are 7,8, and 9 wired inside the motor. I am trying to visualize the inside of the motor. I understand 1 and 4 are 2 windings, 2 and 5 are 2 windings, and 3 and 6 are 2 windings making a total of 6 windings in the motor but when 7,8,9 wires are popping out of the motor I don’t understand how they are wired inside the motor.

Thank you for the explanation and difference between the "Y" and the "DELTA" connections. When would the "Y" connection and the "DELTA" connection be used?

@SACalkins1

3 жыл бұрын

You would wire the motor according to the electrical system you are using( houses are mostly Y). The voltage of the system, and the number of leads on a motor. This wiring is just a 6 lead wiring. examples of other wiring annawiringdiagram.com/wp-content/uploads/2019/02/3-phase-6-lead-motor-wiring-diagram-wiring-diagram-3-phase-6-lead-motor-wiring-diagram.jpg

There are systems that start in the Wye or Star configuration because of the massive amp draw is reduced, then using some timers and three contactors will set the configuration to Delta because the motor can run faster.

How will the voltage and current differ between delta and star, if the motor is used as a generator?

If the star or delta connection is an option in any 3-phase motor, does this mean you can use either configuration in order to get higher or lower power output? This seems a bit odd to me, as I would have expected the motor design to be optimised for one or the other (but I am not an electrical engineer).

@@ciberiada01 Interesting. Since I posted that comment I saw another video about the star/delta switching systems that you mentioned. This apparently is intended to limit the huge inrush current that induction motors draw when initially powered (which will be lower with a star connection). Once it's up to speed it can be switched to delta for maximum power, without such a big current surge. Maybe that's the main reason for having the option available. I'm not sure I understand why a motor would be designed only for star connection though.

Indeed I like teaching may Allah bless you abundantly. I have leant a lot.

Thanx keep on

Thumbs up 👍

too good

I love to learn about ac electric machines😋😋

An SCR is a device that conduct electricity in one direction normally for DC circuits, whereas a Triac conducts in both directions. When gate voltage is applied, the device begins to conduct and the gate voltage can be removed. As long as there is voltage across the anodes. Once the voltage on the anodes reaches zero, the device shuts off and needs to be retriggerd again. Usually a triac also is used with a diac on its gate. A diac is a dual is a dual diode that can have an Resistor/capacitor combination on one end that will delay the turn on of the DIAC/TRIAC combo withing a given time period within the sine wave. This is normally used for light dimmers

What happens when you have a motor wired for delta but have wye service? Is there a possibility of burning the motor?

good sir, since star connection is less amps, so is it advisable to run the motor in star conncetion , and then why it is required to start motor in star and run in delta ?, please clear my doubts.

Thanks!

Very good explanation but you left the ending Hanging. You could end like this "Since the Star Connection uses less current thus Motor Connections should be in Star?" or "Since Delta connections produce higher voltage of 400 running of Motors is on Delta?" .. makes better sense?

Is there any connection between three phase motor shown here and three phase permanent generator used in wind turbines? Is there star/delta connection in permanent magnet generator?

Check our video on how wind turbines work, the generator is shown

square root can be interpreted as equal contribution to each other. multiplication means contibution of one dimension for each unit of another dimension. Equal contribution, or a joint.

Next needs to be star delta starters and the time delay switching over. I thought it was super neat when someone explained what it was.
