[GreenKeys] KSR35 : What kind of motor is this?

[Ralph Mowery]

Most  50 Hz motors will run fine at 60 Hz, however they will run faster.   For something like a washing machine  there is usually no problem.  For the teletype machines and other devices that depend on a certain motor speed, the gears need to be changed if you can find the correct gears.

 

You can buy a veritable frequency drive for small motors and set the speed of the motor to what you need. With that you  can probably use whatever motor you have .  Even run the motor faster or slower to do different speeds.

>From J. Haynes July 5th 2018:

A 50 Hz motor should work fine on 60 Hz power - it's the other way you 
can't go (because not enough iron in the 60 Hz motor to run it on 50.)

There was a thread a year or so about motors designed for 60Hz being used on 50Hz and vice versa. One way works, one way does not. I cannot recall which.
