So after finally getting the new belt and running my Heavy 10 to see how she goes I had something weird happen. After about 2-3mins on high speed (belt on the left-most cone) I heard a high-pitched frequency...almost like a whine but not quite and the motor slowed down. Fearing the magic smoke would escape I immediately shut the VFD and therefore the motor down. Waited about 10 seconds and ran her again. Same thing after 2-3 mins on high so I shut her down again. When I had her running on the middle cone she ran fine for however long I ran her. I admit I don't remember if I put oil into the oil cups on the motor. I'm thinking I didn't because the cups are 180º from each other. IOW, on the pulley side on the motor there is a cup and it's facing the ground. On the right side of the motor the oil cup is facing upwards. I think that threw me and it was one of those things I was going to ask you guys about but forgot. I can't take a pic right now but I will tomorrow if need be. I'm thinking the motor thermal might be kicking in because of not enough lubrication but am I supposed to add oil into both cups? The one facing up wouldn't be a problem but the one facing down ..... ??? I'm thinking maybe I should remove the motor (Westinghouse 309P824-A) and inspect it. What's the deal with the cups and do you think I should tear her down?
