Next time try rewinding the armature 5 pole one pole at a time instead of like this. You will have better heat disapation more exact wire loads on poles , very enhanced performance . It se the drop down wire wrind , drop backwards down the slots and not over the top foreward to next pole rather just the opposite hook wire to comm and drop straight down the slot and wind the pole right there and when finished drop the wire back to the preceding pole , stead of going over top advancement.
