For everyone asking amps.. It's most likely a 480 volt machine so 135 amps. It's not finished so I can't count the poles but I would guess 1800 RPM (4 pole) and the dude did a fine job installing that coil.
@@frankmartin6126 You are CORRECT, it's a 60 slot 4 pole and the heading say's 65KW I doubt that, it looks like CAKE 20 HP 1800 RPM and being a generator probably Delta connection. Nothing special here. This stator should have been stuffed 90 minutes or less, then connected and lashed another 90 minutes. You can't hardly get a job this E A S Y to fill the slots. Every winder knows to FAN the coils before you insert into the slot, These are the ones that you wind in your sleep / eyes CLOSED...
as the commentator said yes they do you need to hit the coils down or you will never get the next one down the last varnish secures the whole winding if a motor was not varnish the wires would vibrate and create shorts eventualy blowing up varnishing a motor will keep it working in an ideal enviroment till the end of time.
That is a precision and labour intensive job. interesting that you tap the windings with the rubber hammer. Do they get an additional layer of varnish ?
i ddint see the motor getting dipped in varnish.?r they spraying the varnish or what. iam confused.iam a winder too. i work with kerala water authorty . i have done upto 150 hp motors here. i heat up the whole motor after winding to take out any moisture. then pour vRnish on one side keeping the motor vertical so the varnish oozes out of other side let it dry for one day Nd turn the motor opposite side and pour the varnish and let dry of it. i ddint see any dip/pour varnishing here.the varnishing process should have been shown. any way amazing and interesting video. thanks banglore dudes.
That was some pretty brutal hammering going on with those coils at the end. Damn. There's no WAY that doesn't occassionally cause a shorted turn in a coil from where two wires were smashed into each other and chipped some insulation off...
1:12 UNBELIEVABLE ! ! ! Tamping down THIS coil, it has N O cross-overs. If he would have FANNED out the coil before inserting in the slot it would have F A L L E N with a twist of his wrist? ? ? To ALL of the Motor Winders viewing this video, you have to know this stator is as *** C A K E *** as they come. Average stack, W I D E Slots, EMPTY SLOT 1 - 12 span probably 72 slot 12 groups of (6) and 3 wye connection. Should have stuffed / connected / lashed before lunch. Pre-heat and dipped at 1:00PM after lunch break. LOL... Oooop's I just saw the phase cloth and I was WRONG only 60 slots, even EASIER... Hahahahahaha.
It's a generator. The leads all come out . It is easy but you have to know what your doing. This guy is a good winder/mechanic he has done it for years
That thing there is not a cat generator. A cat generator has cats and robotic arms that rub balloons against them. Then sparks fly, the cats get excited and start chasing electrons all around the machine and into a little hole that connects to ...whatever.
+dennis lowe taking too long to insert one coil many i had that motor wound in 4 hours top.motor probabably only have a 1wye 3 leads connection simple shiet.

Groups of 5, 1 to 12 span, most likely 60 slot, 12 groups of 5, 4 pole

Great job dennis. I think your a good winder. I'm more impre5at the views you got. That's why they call you a rock star. Diamonds
Oh, it was so funny! I was like "Oh how precise!" *fast forward to pounding with a mallet*

This what i call a "GRAVY" job.
1:36 Hammer time.
That is a precision and labour intensive job. interesting that you tap the windings with the rubber hammer. Do they get an additional layer of varnish ?
Yes it gets dipped in varnish after.you have to shape the winding with the hammer or you could never wind the motor .it is a rubberized hammer .
Hi Dennis how do you connect those coils start and finish side thanks.
Nice
How many watts and at what rpm?
can you tell me please how much copper actually went into the whoel winding

Good vinder me vinder
What is the name of the company in this video doing this work?

Sir muje Mega wat ke bare m kuch knowledge leni h
Yes, how many amps please? At what rpm's?
1800 rpm. It's a generator. Probally a 150kw so typically take 1.2 x hp for a 4 pole
What connection of. That motor bro?
It's a 24 lead in parallel. Meaning 12 leads. Most cats that size are like this
how many amps
Winding = coil = loop of wire ??

I do this job.
To slow, in my day 1971 we would have to insert and sew and have it ready to connect leads in 2 hours or less
sir 20hp abb 72slot motor कनेक्शन बताईए plz900rpm
NO feeders and seperators not long enough you need more training.
if you need feeders and longer seperators on a job like this then you need more trainig ..
+dennis lowe taking too long to insert one coil many i had that motor wound in 4 hours top.motor probabably only have a 1wye 3 leads connection simple shiet.
Yup actually it was a y delta connection with 12 leads so still simple.
dennis lowe That"s what i call a 1&2 circuit wye delta connection.
What is this, a battle of who's more intelligent in winding and what you know about stators?? You guys really need to get out more often.
