NORMAL FORCE VARIATION IN SINGLE-SIDED LINEAR INDUCTION MACHINES
A basic 1-D model having a single harmonic current sheet supported on infinitely permeable iron, an air-gap, a conducting layer and a backing region of air or iron is discussed. By making certain simplifying assumptions, two circle diagrams can be derived, one for the model with backing iron, the other without. It is shown how the idea might be extended to include normal force and machines having air-backed rotors. Simple formulae are derived for certain factors such as complex power/newton of normal force.
