## Homework Statement

I studied that as the single phase motor speeds up the backward induced field currents are larger than the forward field currents. So , the corresponding opposing rotor mmf causes backward field to be greatly reduced whereas the smaller forward currents leads to enhancement of forward flux wave..

I am not getting this fact as if the backward current is higher so even the backward flux should be greater . Then , on what basis the forward flux is greater???

## Homework Equations

## The Attempt at a Solution

The backward field currents has a lower power factor whereas the forward currents have higher power factor .[/B]
