Flux Cutting Coil

The total flux cutting a single coil can be calculated in order to investigate the force reacted and emf induced.

Figure 5.6: Derivation of flux linkage cutting coil

Referring to Figure 5.6, the flux linkage of a section dr of a coil is equal to the total flux, multiplied by the number of turns contained in that section, (dr/ch).N. The flux linkage of a single coil will be an integral of this value in three dimensions, as shown in (5.6).

Where cw = coil width (m) g = airgap (m) ch = coil height (m) See also Figure 3.13 for dimensions. This value is assumed to be the peak value of a sinusoidal variation of flux linkage with coil position across the entire rotor pole
