Was at a customers oiling and greasing machines and fixing what they break and went into the other part of there business, saw some brand new Baldor motors 1/2 HP 110 Volt 7,500 RPM, but they only have a 5/16 shaft, they run a mixer off these. Just thought that I'd throw this out there.

Odd voltage/speed.

maybe they were DC motors? Fastest 60hz AC motor is 3450 nominal RPM.......

J T they were AC/DC 110 V maybe there is a DC conversion in side the housing.

Universal Motors,(Series motors), they will run on AC or DC.
RPM restricted by loading/friction etc.
Baldor owned by ABB now.
Max.

ABB, Rumsfeld was on the board when they failed to deliver power stations to Korea.

Didn't know they made universal motors, I know they make induction and DC.

Those would be universal, which I would have "filed" under DC anyhow.
