Manufacturing difficulties and corresponding high costs : for control of uniform air gap (axial magnetic attraction) for laminated sheets and teeth of the stator for windings arrangement : asymmetry 5/21 Problem of space with end windings at inner radius
6 I. Introduction Consequences of manufacturing difficulties 1> Use of Soft Magnetic Composite? easy to cut slots 3D magnetic property New process of fabrication 6/21
7 I. Introduction Consequences of manufacturing difficulties 2> Simple arrangements of the winding Consequence for 3-phase axial machine Toroidal winding No distributed winding flux linked by one phase is not sinusoidal Non-sinusoidal Electromotive forces except with special shapes of magnets Concentrated winding 7/21 No performant vector control with weak torque ripples
8 I. Introduction Two interesting points of multiphase machines: 1. performant vector control with weak torque ripple even with non-sinusoidal emf 2. intrinsically fault-tolerant machine (already used in electrical ship, future offshore wind generator?) To sum up For performant vector control (torque quality) Multiphase machines impose less constraints on the designer than three-phase machines 8/21 It is particularly interesting for axial-flux machines.
