The motor is built with a number of magnetic poles arranged around the stationary part of the motor (the stator) alternate poles are wound with the two different windings. By connecting a capacitor in series with one of the windings (which results in a phase shift across that winding) you get a rotating magnetic field within the motor. The permanent magnet rotor aligns itself with that field and rotates to keep in alignment. The direction of rotation of the rotating magnetic field depends on which of the two windings the capacitor is connected in series with.

What is the purpose of the 0.15uF capacitor?
I find the next size smaller shows it also in this picture:

Since there appears to be a capacitor present the motor in the picture is wired correctly. If there were no capacitor it would not run.

There is a wire diagram on this picture but it does not help me.

Do all 3 need to be attached to make it go clock wise?
counter clockwise?
Which wire is neutral?
Which wire is is hot?
