Is the tension on a slipping belt higher than just before it slips? It might be less After all, the slipping belt has stopped transmitting torque. This is the real question I’ve never measured.
A really cheap solution is to put a low-amp fuse on the motor. Not a breaker, a fuse and keep them in a locked cabinet. People will soon learn to take it easy. > On Jun 7, 2025, at 7:58 AM, Roland Jollivet <roland.jolli...@gmail.com> wrote: > > Why don't you use an idler pressing on the back of the belt, on the tension > side, indenting it slightly.
