I bought an old Wards 8" Hammer mill last spring and it came with this equally old Century 3 hp, single phase, electric motor. According to an old MW ad I read, these motors were offered with the mill. It is a big bassard!
I plugged the motor in, for the first time, today. It is wired for 110 at the present and it took right off, smooth as butter. After about 5 minutes, it made a semi "clunk" noise, slowed down quite a bit and I quickly unplugged it. No smoke, not hot...no obvious signs of self destruction. I plugged it back up and it just hums and won"t start.
I am an electric motor moron and freely admit it. Even at that.....I think these repulsion start motors have some kind of start winding/clutch gizmo that starts the motor, kicks out and then serves some other function while it runs.
Whatever....it won"t start or run now. So, would some electric motor specialist please stand up and offer a suggestion as what to look for and how to fix this beast. I don"t think it is anything major...but it could be. My intention is to change it over to 230 volts for lower amp draw, if and when I put it in service. Thanks.
