MOTORS REWINDING

Hello "Guest",

Your Question is not possible to answer in the present form.

I presume you intend 1 Phase and 3 Phase motors.

But you have failed to state what type of motors each phase type actually is.

Reply here, with

Kind Regards....

Sparkstation, Is this it ? Is this all that you can actually do ? Please change the record. I have looked at two of your responses today and they are both the same. It is actually becoming boring at this stage to read anything from you.

I do not wanna disappoint you but your question is incomprehensible and it sounds like you do not know what you are about to get yourself into.

The others must feel the same, I'm sure, and that is why they respond to you the way they did.

Many do not respond at all.

Please answer my simple question, are you new to motor rewinding or you are a Do It Yourself guy. If you want to know the winding better join as an apprentice at some winding shop. If you cannot differentiate 1 Phase and 3 phase, mind you it is not 1st and 3rd but Roman Numerals are used as it is I aka one III aka three) don't venture into rewinding which I am sure will result in huge fire and loss.

Your question is posed in a manner that makes me think you are in over your head !

Sorry "Guest", but Sparky & 'Dad' are totally correct...

your post asks: "what the right connecting style is for 1Ø and 3Ø motors..."

This question cannot be answered becaues there are SCORES of "Right" connections, depending on a lot of different factors. Saving myself some time, here, look at my posts to similar topics (on CR4) at:

If you want a "Simple Answer" ((instead of being pointed to lots of GOOD Reference material)) then you simply MUST provide excruciatingly-detailed information in your question ... which ... as has been pointed out, it does not seem that you are equipped to do.

Wishing you well ~

Might this be what u expect?

1- Single phase windigns(split phase actually):

2- Three phase windings(Star):

In an average single phase motor, two of the wires are connected while the motor is running. The other two are connected to a start coil that ensures the motor begins to turn, and turn the correct way, when the power is applied. The start coil needs to be connected in series with a starting capacitor and fed via a switch that turns off when the motor exceeds a certain number of revolutions per minute.

In the absence of the manufacturer's data and the size of the motor it is very difficult to advise further.

Generally, rewinding a motor is a specialised operation that is best entrusted to an outside agency that specialises in the field <sorry about the pun>. With the rewind service purchase comes a performance warranty that in many cases exceeds the value of the purchase price, as far as the end user is concerned.

You have had some good answers, in spite of supplying very little information, are you happy with the answers given or do you still need help?

Also, please also do not forget that this area can be quite dangerous for someone with no proper electrical knowledge, and we do not know the level that you are at......so we must be careful in what we tell you.....assuming better knowledge that you really have could get you killed!!!

these out coming wires are depend on your motor design because pole of the stator's and then armature of the motor winding each part having seperate winding the we gave one common supply to their

Hi guy

It depend what the last faze if not next then becaus if it supply there to in for wire system then ac power reversle canot start it. This always happin when conneck first faze to primary fazes.

Hope this makes it.

yore reply maiks the hole mater kleer

Thanks for all ……..

Guys!!!!! I mean by my inquiry that how to wire the windings internally ,,, by other words,, after putting the turns into their slots according to a proper winding step ,,,,, therefore we'll be getting a number of groups "inside a motor" , based upon the number of each poles & slots ……then what's the connecting style among these groups internally in case of ::::

1– single phase motors "with capacitor , centrifugal switch " …

2- three phase motors to get 6 wires coming out of a motor,….

Please demonstrate with figures if possible

Thank U

Hi guest

I'm trying to do my best regarding the common connecting motors' laws , despite I'm convinced that there're lots of motors categories , that's why I think this subject is as large enough as the sea , it takes a lot to talk about it in particular ……. Look!!!! These laws are related to the Squirrel-Cage Motor, no matter if it is a single phase motor or three phase;

1- The connection of a group

-"any number of the induction coils in the same group are connected in series , &

the current passes in the same direction , therefore they make one group"

2- The connection of many groups

- if the groups of turns are neighboring ,then the connection will be " end to end" ,& the current goes in an opposite direction …… otherwise the connection is "end to start" ,& the current goes into the same direction.

I need assistance because I can't attach any figures by " copy – paste "….. so the forum's administration …………………

Hello Ali18

Are the "figures" you refer to, pictures or graphics.

If pictures/graphics, these cannot be copy/pasted into the text edit Box, where the message is typed.

If so, and you need help, please refer here: http://cr4.globalspec.com/thread/15743/How-to-insert-Graphics-into-your-Post-to-make-it-more-readable-or-interesting

If the "figures" are of a different sort, advise here, with

It is not that the letter is not English sentax even if spelling and punctuation is bad it would not matter. The problem is this letter "Motors Rewinding" is alien babble to seem like it is about electrical engineering in quasi English. I will make an an attempt to be a translator for you and hopefully I will be somewhat on target to what you are attempting to communicate about your concerns about rewinding motors.

I believe what you are saying is you have a number of sample motors (broken and can not test them in a working state) you do not know the phase of these motors and there are different numbers of wires and colors in these motors that are different as well. What you would like to know which motor is which kind of design. Then you want to know how to find the type motor once you have determined what design type themotors are; then you want to know how to rewind the motor. Is that correct?

Problem is there are various types of windings even in specific types of designs in order to have different speeds as well as the phase the motor runs on. There are also hard start and soft start motors. So, I would see what type of function they had first and determine what the wiring might be on each determination. There are so many kinds of motors and configurations, it is scarry. If you can find the manufacturer and model number and go on the Internet to see if they have information at the Web site for the company. Motors are not usually rewound unless they are very big, it is not worth it economically, or if you don't have the money and plenty of time perhaps or there is no other way to replace the motor then rewinding is an option. I have rewound transformers and it was a pain in the ass, with the plates and not kinking the wires. There was a motor kit I wound when I was a kid that was a polyphase design and I made one other DC motor from scratch with a nail for electromagnet wound crudely and some wood and wire to run on a battery commutator on wooden shaft it nedded a kick start and was without much tork, for demonstration only, or maybe could be used for a ride for fairies and butterflys.

first of all , are you the guest who asked for help , or probably another one shows his muscles in both the electrical engineering & english !!! .....

Hi Ali18,

What a speed is this? Why r u so excited? How did u understand that he refers to you?

Please be calm...This is better than regret.

sincerely
