if a belt is put on too tight can this cause permanent damage to a PSC motor?
I got a call about exhaust hood not working, went to restaurant and found the belt was slipping and completely worn out. so I found a belt close in size and put it on and tightened up. The hood itself said belt size-AX27, it had a AX25 on it, all I had was a AX26 so i put it on and tightened it up and off I went. I mistakenly did not check amp draw at that point, which I should have. So five days went by and the restaurant called again saying exhaust fan comes on runs for a bit then shuts off. So I go see whats going and could tell the motor was overheating could barley touch it with my bare hand. So at that point I loosened the belt up just a tad and took an amp reading it was pulling 9 amps and RLA is only 7 and from what I understand motor should only be pulling about 75% percent of RLA or even as low as 50% . No matter how loose I made the belt it still would pull close to 9 amps. So now the motor is going to be replaced, but did I permanently damage the motor by having the belt on too tight? or is there something else going on here?
