</div>They are 120v 60Hz A/C synchronous motors. They could be used in<br>
clocks, washing machine or clothes dryer timing dials, etc. I have one<br>
in my Hammond organ that precisely sets the tuning of the instrument.<br>
It spins the electromechanical tonewheels at the correct frequency to<br>
generate the tones for musical notes, hence the organ is not tunable and<br>
everything else has to tune to it. In fact, Laurens Hammond was<br>
originally an electric clock inventor and may actually hold the patent<br>
for the motor itself, if not its use as an electric clock timebase.<br>
