Abstract:
The problem discussed relates to the calculation of electromagnetic travelling fields in electrical machines. The idealised structure considered comprises a number of laminar regions of infinite extent in the plane of lamination and of arbitrary thickness. Some or all of these regions may be conducting and/or ferromagnetic with constant permeability. The travelling field is produced by an applied current sheet at the interface between two layers, distributed sinusoidally along the plane of lamination and flowing normally to the direction of motion. A convenient reformulation of existing theory is suggested which simplifies calculation. The normal limitations imposed by the amount of algebraic manipulation involved are removed by the use of transfer matrix. This provides the facility to the introduce numerical values directly into the matrix formulation.
