Is this a very poor description or am I ignorant?...

*What exactly is the Work of Start Capacitor?*

For single-phase motors normally have both the run and start capacitor.
However, they work differently. The start capacitor produces a bolt of
energy to the motor for it to run; while for run capacitor helps
maintain the functioning of the motor when the start capacitor switches
off. Start capacitor has the ability to store more charge than the run
capacitor.

Something else to observe with a start capacitor is getting burn out
since they work is to accumulate energy to speedily burst it out to
start the motor. How can you tell if the start capacitor is bad? You can
identify through two signs. First, when your motor is not starting after
you ignite it as usual, or if it takes longer than expected to respond.
It means the start capacitor is dead or almost to go bad completely.

 My explanation would be, the run capacitor causes a phase shift of the
current in the start winding, this in relationship to the main winding
cause an increase in torque to start the motor.

I think they are using more of a DC analogy, that I don\'t think applies.
