This describes a single phase 2850 RPM motor. Can such a motor be run
from 60 Hz?

Yes, but it will run at 3420 RPM.
Thank You, Randy

50 Hz on 60 Hz is not problem, it just runs faster. 60 Hz on 50 hz usually won't work, there's not enough iron in the guts and it would run slower anyway as well as overheating.

Funny, we have around 400 60 Hz motors running on 50 Hz David

It will run, but might not produce the rated 1HP at 120V. Call Baldor for a better estimate.

Wrong. 50Hz motors can always be run at 60Hz. 50Hz motors cost a little more because they have to be wound with a little more copper. 60Hz motors can't always be run at 50Hz, but 50Hz motors can always be run at 60Hz.

The OP might have meant torque rather than horsepower. If so, he would have been right.

More things are at bay than just speed - and that is a natural.
Power is most important as well. Sometimes there won't be enough power designed in a core that is to large for the frequency provided.
A low frequency has a large core, high frequency uses lighter cores.
The core size - mass or volume determines the power ability.
It might be just fine. You might not ever need the full power either.
So you might have a ok dual frequency motor or just never need to push it the full extent.

Yes. Almost any 50 Hz motor can be operated on 60 Hz, and visa versa. Voltage, RPM, and output power scale with the frequency. For this motor the factor is 60/50 or 1.2 so 2850 RPM goes to 3420 RPM, 110 V goes to 132 V, output power capability will go to 1.2 HP. Current will stay the same as 50 Hz. It will think it is running on low voltage, but because this motor has a service factor of 1.25 you should have no problem getting the full 1 HP, even if it runs a little hotter.
