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