Hi. Can someone explain the use/operation of a start capacitor in a single phase motor?

 

Hello,

Take a look at this page:
http://www.clrwtr.com/Single-Phase-Electric-Motors-Characteristics-Applications.htm
A bit down the page the start capacitor is named.

This is a link from the EDUCYPEDIA page on single phase AC motors:
