My experience is that motors designed for 60Hz do tend to run rather hot even if they have universal motors. A friend brought a radial arm saw back from the US, you couldn't use it for more than 5 minutes before it shut down and had to be left for 10 minutes or so to cool down.
In the 1990s a local nut processing plant opened and purchased all their equipment from the USA. I use a local engineering/metalwork shop that was doing their work.
I remember seeing boxes of discarded US power sockets, wire, fuse boxes and other gear, along with a few large 3 phase squirrel cage motors sitting in the workshop. Asked him out of interest what it was from and he mentioned the nut place and how motors were constantly burning out, and needed to be re-wound despite being run on 120v via a large transformer.
the motors that were in his workshop were being sent off to be rewound after cooking.
Informed him of the 60hz problem, and that the only solutions were to
1>make the 120v into 60hz using some sort of converter.
2>replace the motor with a suitable 240v one, but the RPM would be lower.
Also to make matters worse, the gear was running probably 1/6th slower than it was designed for.
depending on the cost and loss of efficiency in the conversion - using the converter was probably the best option as replacing the motors would have resulted in the equipment still running slower than intended, and changes to gear ratios/pulleys etc would probably be needed if this was an issue.
I informed him of all this, I don't know the outcome, the place closed down a few years later.
I've found the only hand dryers that really work well are the Dyson type. Bought a Dyson Fan which I reckon at $500 (Harvey Norman) is expensive but looks nice is quite and gives a perfect breeze. Wonder why the copies aren't out?
Oh dear Rod is out of ideas, always the same when he doesn't have an answer, out come the same tired old insults. He hasn't managed to think of anything new in the last 20 years.
Roddles if you are trying to insult someone please be original, I know it is not in your nature. Original thought belongs to us more highly evolved humans, but try please, atm thought is not illegal. But in your case impossible. Have a good day in your unevolved small world.
