Two ways to go
1.
B&Q sell performance power table saws so contact nearest branch for contact details of either supplier to B&Q or manufacturer of the Performance power tools.
[ or head office if you get someone like Consepta of Corrie street 'I doooon't really knoooow' don't forget ask for head office telephone number.
2. www.rjweng.com/electricmotorsrepair
and get a match or they may be able to repair existing unless it's really knackered.
