Short version: Anyone know if the 240V Dremels differ from the 110V one in the motor windings, or the controller?
Longer version: I have a variable speed 240V Dremel. The (cheap, internal) speed controller on this broke a while ago. As an interim fix I bypassed the triac- based controller and have been running it with a variac.
I have been thinking of fixing the controller, but it occurred to me that a better/more versatile approach would be to run the drill from a proper speed controller, these being pretty cheap these days from eBay etc.
But I am not sure if a 240V-based one would work, since (I am guessing) it is possible that the UK and US Dremels share the saame motor, and only differ in the controller.
As I write this it seems less likely than I originally thought, but I would appreciate any information on this.
Thanks, J^n
