Looks like a nice little fan.
An AC supply just goes up and down in voltage, it has no specific direction like DC.
To get an AC motor to rotate, two (or more) supplies are required with one supply running in front of the other. This gives a rotating magnetic field which the rotor follows. To get two phases, one supply is fed through a capacitor which advances the phase. Some motors switch out the capacitor when the motor is up to speed, this is capacitor start. Some retain the capacitor, like this one, as capacitor start and run. This saves a centrifugal switch.
Some small fan motors are shaded pole. The motor poles are split and a copper ring is placed around one half. This gives a phase retard to give the motor direction. These motors are uncased and so the innards can be seen and they are very inefficient so run hot.
