    Greetings from The Netherlands. At the age of 13 (1966) my neighbor asked me if I was interested to do some work during the summer holidays. I had trouble at my previous school and was interested in electrotechnical stuff. He was rewinding electro motors. I started taking ball bearings of broken down electro motors. Legally I was not allowed to work at that age, but I did very well and learned a lot about these things. After that summer holidays I went to a technical school and learned other things. Next year I went back to the electro company and learned a lot more. The year after the 3rd summer vacation in that company it entered the electrotechnical classroom in that school and recognized all the types of electro motors. I started talking about it to my new electro teacher ;-) . He made a remark that it was special I recognized those different motors. I told him I could even explain to him how they worked and even how the windings were calculated and replaced. I saw him getting white around his nose... What am I going to do with you? You know more at this moment than I will ever teach your classmates in the next two years! I became a measurement- and control engineer.
    You brought back lots of memories. Thanks

    Watching this video brings back so many memories of working with my dad in his motor shop. He started in 1935 at the Brooklyn navy yard and spent the rest of his life winding motors. I worked with him from 1960 to 1982 when we sold the business. I moved onto other things but while the equipment has changed the work is the same. Thanks for bringing back all those memories.

  • @davidhollfelder9940
    @davidhollfelder9940 11 месяцев назад +6

    Back in High School (early 70s), I was in a motor repair shop class .. people would donate small motors (fan/shaded pole, 1/4 or 1/2 single phase induction motors, etc), to repair/return or repair/keep. We were taught how to measure and count the wires, and make a “skein” winding former. We’d wind the coils by hand, counting the turns. Sometimes, it was only the starting winding and centrifugal switch needing replacement .. sometimes bearings too. We even converted a couple 25 Hz motors to 60 Hz by increasing the AWG, and reducing the turns (via formula). I’ve repaired some motors since .. it was a very memorable shop experience .. seems just like yesterday. Thx for sharing.

      @@MrMaxyield you're probably correct about the cost. Seemed like 125hp vertical sells for $14k new online... This shop had a lot of people working on rewinding this motor if they're only charging lets say $7k .

    Brings back memories of my days in the navy. interesting to see what has changed and what has not changed in 50 years. My ship was deployed as flagship for 6th fleet and we were all alone. No facilities for support and no tender, so the ship's electricians were always rewinding motors. As I recall the largest was a fire-pump motor, 400hp. Those guys were great.

    Thank you for sharing the rewind. As a kid I was always fascinated with motors and how to rewind them. There were some books I learned from and as a hobby would get these motors that were smoked and rewind them. From what I have learned by reading, was able to take the bare stators and calculate the turns and CM to fill the slots. To calculate the CM, I'd just fill the slot with a hank of say 17ga wire and had the volumn. I could wind 3 phase motors to single phase and had to start from scratch. I used 5 coils per pole in a four pole 36 slot stator. The coil pattern I copied from a Westinghouse motor, span slots 1and 7. The poles would overlap on the outside coil. I think this was to help reduce harmonics ? ? Well, That was many years ago and don't remember how to do that math anymore. Now I have a new, ! ! ! well getting older hobby that bacically doing nothing (retired) as very soon will hit 78 years. Your well done video brings back memories and I'm impressed with the task you have done. To me that is beautiful the way you done up the inside that motor. Too bad it has to be covered up but, yes the protection . I do appreciate the old open motors which you could see the formed coils. Take care ........... Gary

    I was a winder for 20 yrs in Youngstown Ohio. retired from that profession due to carpel tunnel.. I only used that kind of manual winding machine for small coils or very odd custom ones. we had a German cnc machine that made very precise coils that made it easier to install and also allowed you to wind as the machine was producing. stay fresh my friends!

    My dad did this and i was lucky enough to work with him for a short time. I struggled learning the connections, but all the winders would work with me. Spring was always job security with the storms. It never failed, an OT rush job would come through about 4:15.pm on Fridays. Nobody would be able to take it, so dad and i would. Always seemed to be a form coil job. Loved doing those, but hated the fiberglass tape at first 😂.
    A big part of me wishes i would've stayed with it. Heck if i had the tools, ovens, coil machine, dip tank, etc i would do it again. Thank you for sharing this.

    These are a huge leap from the tiny little hand wound tx's I made that were soldered onto the handmade pcb's of hand held flow meters I used to manufacture , start to finish at a small factory in Southport UK back in the 80's.

    As a 15 year old apprentice in Sydney Australia I wound the coils for motors to convert 240 volt to 110 for the computers IBM and for hotels .This was in 1965. Is put a tap in each coil so that they could be adjusted for voltage fluctuations.This was before any switch gear became digitised.

    In my younger days I worked in a technical college where motor winding was taught. (These days for small motors its cheaper to buy a new one.) Not as big as this beauty but small basic motors. Who would have thought your video could be so interesting, just winding a motor. But I have been spoilt, videos of Indian guys rewinding motors on the roadside, yours is basically the same but not done on the dirt outside, yours is a much cleaner environment, same principle though. But I digress, a very interesting video my friends, fascinating really, great to watch professionals at work. Well done.

But depends also if its a special frame or other factors. Also all DC motors got rewound regardless of HP

    I never realized the copper wires in a coil are coated and insulated from each other! Is this the same in all electric motors? Like is this done for the copper wires that make up the coils in small DC motors too, or is it only necessary for larger ones?

      I’m no expert, but yes they all will be. It’s called enamelled wire, at least here in the UK. It’s a thin coating that insulates the wires. Handy for doing PCB repairs, and other things, as the enamel can easily be scraped away.

    So how much does it cost to rebuild this motor compared to the price of a new one?

    it was blowing my mind you could do that so easily but i suppose you have already done it a few thousand times. Even so you need to be able to have some committment and believe you can do such a complex task to completion.

    Nice job Guys, I am on HVAC-R business and dealing with motors all the time , only thing I didn't see is evacuation for feeding varnish material and get rid of the air bubbles , and baking procedure. are those common practice for all motors or there are specific motors needs such procedure? Are these procedures for high HP motors or for smaller motors such as 15-30HP shall be applied ?

    I have atech question of a 25hp 3phase motor. I have a difference of opinion of bearings should be open on outer side vs leaving them sealed as they come from factory. I want to remove 1 outer cover of the sealed bearings so the grease gets in.
    What is your opinion?

    Good and wonderful work. Is the method of winding this motor in series? I want to know the division. Is this the same small 3-phase motor or is there a difference?
