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.
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.
