Electric motor with T1-2-3-T4 terminals

I have an old electric motor with T1, 2, 3 and T4 terminal connections.

The specification label of the motor is painted over I can't read it.

The motor is about 10 inches in diameter outer case. Pretty heavy.

Can anyone help me determine if I can wire it to a 120 supply?

I found this tech info:
Motor Doctor Article Detail - Century Electric Motors - Regal Beloit EPC, Inc


But off hand does anyone know T1-2-3-T4 and how I might wire it? WOuld prefer 120 volt.

Thanks,

Dean

Does your motor have a centrifugal switch? Some of the old motors from the 1940's were cast iron and heavy. You may have two winding sets. You could use a meter to see if T1 and T3 are one winding and T2 and T4 are another. I do know that some of the old GE motors used T1-T3 as the run winding and T2-T4 were the start winding. On start-up the centrifugal switch is closed and both the start and run winding are connected, when the motor reaches a certain speed the centrifugal switch opens to take the start winding out of the circuit. If you have a centrifugal switch you should check to see that the mechanical part slides freely otherwise the switch will not open and the motor will overheat. The only other suggestion I could make is, if in doubt take the motor to a rewind shop and they could probably tell you all you need to know.

Great advice thank you. It is not cast iron - not that old. Take to a shop is a good suggestion as well.
