How to power Sumitomo Sm Cyclo Motor?
I did not see the motor face plate when I first looked went back to get the motor number and did see it. 115/230V so it can run on both voltages. You will need to verify how it is wired and compare that to you want. It is easy to change the connections in the "J" box on the side of the motor where the power leads come out. The wire connection diagram is just behind where the cord is cut off on a silver sticker. The wires are usually numbered, stamped into the wires or have tape numbers on them. Added: Here is a link to there motor selection chart. On page 5.7 the connection diagram shows: 120v connect T1-T3-T8 together to white standard plug, T4-T5-T2 together to black plug. The ground to the screw to the frame. The wires may just have a number stamped on them if there are additional wires tape or wire nut the ends.
To run with 240V: Connect T3-T8-T2 together connect 1 hot to T1, connect T4-T5 together with the other hot, ground goes to the screw in the motor "J" box.
Running the motor with 120V will draw (6.4 amps) 2x the current as the 240V (3.2A) connection. This information is shown on the motor face plate. the starting current can be as high as 525% as listed on page 5.14 of the link.
I did not see a thermal overload listed for this motor. Overloads are set at 115% of the above currents to protect the motor if the output shaft is locked.
Since this is a machine that you are going to be working with while running make sure to turn the power off if the motor stalls or the stater winding's will overheat and the magic smoke will escape. Good luck looks like a fun project.
