Specs shouldn't really change after a rewind.Maybe the rewinder has dropped a wire gauge if the stator had tight slots or maybe the iron core had been damaged by too much heat applied(if used) during stripping of the stator.33 percent is a significant change for current draw.

Looks like it has been "poling".Could even be something like a broken shaft inside the rotor core,or loose fitting of rotor to shaft..

You may find your info here.....https://library.e.abb.com/public/546075431764011cc125755c003a260f/P34AMK039510_EN.pdf at around page 60

Probably easier just to make one....sorted

Looking at the sequential burn marks on the commutator in your first post,I would say the leads have been layed down in the incorrect order.What was the commutation like under load?...There must have been some unusual sparking there..

It will "hum" it head off...been there done that..

G'day MAC3382...This may be of interest to you.. http://www.indiamart.com/trophy-tech/

G'day elinBG...Here in Australia,that bearing is known as a 6014....Have another chat to your bearing supplier,sounds like he may need it..

What colour spark do you have at commutator....Green usually indicates an open circuit coil,blue ususally indicates a shorted coil....

why 2.2Kw....equals the old 3H.P.

Looks like you have "slung" alot of solder as well...

may also be an open circuit rotor bar.

green spark may indicate an open circuit in the armature windings...a blue spark usually indicates a short circuit.
