Auxiliary Winding in a Split-Phase Motor
Hi, looking at split-phase motors, I understand the purpose of the auxiliary winding, however I am little uncertain about the following statement:
"The auxiliary winding is designed to have a higher resistance/reactance ratio than the main winding (Ra/Xa > Rm/Xm)"
I guess I am having trouble understanding how the mathematics of this statement allows for the auxiliary winding current to lead the main winding current. Any help is much appreciated.
