I have a cut off saw thats about 30 years old and today it decided to start transmitting 120V through its chassis! Luckily no one was hurt but if I removed the internal ground(earth) the voltage drops to 50V ish. The switch connections look great not sure what has happened.
Hi there, glad you enjoy our content all the way over there in the Philippines. We're not sure what the HP is on this motor as it was filmed last year. Apologies.
I started as an apprentice armature winder in 1961 in Torquay. Nothing has changed much except we use to listen to the Beatles on the radio.😂 Thanks for the video.
Thanks for the comment, Tony! Always great to hear from fellow winders past and present. Our guys will often have BBC Radio 2 on in the background so you get the odd Beatles tune from time to time.
I fell into this rabbit hole while researching generators, but really appreciate the video and explanations. I’ve always wished I would’ve been exposed to this type of work and am grateful you took the time to make this video. Cheers from the U.S.
Thank you! We're always trying to improve our explanation videos and are pleased that they get viewed all the way in the USA. Hope you found it informative.
They are repairing something to factory condition, not customizing it. Pumps like that will run for years or decades even with those supposedly wrong sized lugs.
@@largerPOTATO using the correct size lugs would be to factory condition in your words. Also I think I might have a better understanding of what they do as I worked there for 4 years.
Sorry, you don't like our choice of music. The best thing to do is to hit the mute button, then you can listen to whatever your heart desires. Maybe some Taylor Swift, or Slipknot if you're that way inclined. Also hit the subscribe button on our RU-vid channel, but chances are we'll have other stupid music on our videos.
Are you trying to learn how to rewind an electric motor online? We do our best to document the work our rewinds engineers do, but it's almost impossible to do a step-by-step guide as there are loads of different motor types that need their own wiring configurations. This video isn't a comprehensive step-by-step guide. We do have some other videos that might help you though.
When stripping out the old coils, it's recommended that you make a note, or take pics of how the windings were originally inserted. You'll also need to have the same number of wires in each slot as previous.
I mean, can they rewind your motors..??? Yes. Can they rewind them well…??? Kind of… 1: using a torch to burn out the old insulation out of the slots is destroying the laminations. Probably wouldn’t pass a core loss test after that. 2: just pouring the varnish over the winding like that isn’t very good… now with that said, for small non premium efficient motors, you can get away with that probably. But you should really be doing a full dip and bake. Meaning, having a bin full of varnish and completely submerging the motor in the varnish and letting it stay in there anywhere from 15 minutes to an hour depending on motor size. Other than that, the in ding looked really good and it was obviously someone who has wound motors awhile and cares about how it looks.
Hi Bailey, thanks for the detailed comment. After reading your notes and re-watching the video I just wanted to assure you that the motors are submerged in the varnish for every rewind. We have a huge bath full of it that the motors go into before going into the oven. Our social media accounts have a few videos of them coming out if you wanted to check those out. The guys in the workshop have years and years of experience and work on motors every day. But, this video was put together back in 2017 and doesn't show the full extent of what's involved. If you have any other questions about how we do things here, please don't hesitate to ask.
I wind my motors with EASA accreditation, core loss & hot spot test, burnout for 10 hours at 700°, take data & strip, media blast, core loss & hot spot test again, stuff, meg ohm & pi test, Dip for an hour, drain, and bake at 350 for 6 hours.
