hotpoint aquarius 1100 wm63 drum/motor not turning?

Hi I have a Hotpoint Aquarius 1100 model no wm63 it seems to do everything it should water in and out etc but the motor and so the drum is not turning I suspected the motor so bought a second hand one on eBay changed them over but still the same problem
Only background info I can give is smoke was coming from it when it last worked turned out an insulated spade connector for one of the brushes was earthing on the motor body
Please help
