| Abstract The disc-rotor induction motors come in a variety of structures such as double-sided stator, single-sided stator with iron backing rotor, and single-sided stator without iron backing rotor. This paper presents the field analysis of the disc-rotor induction motor using two-dimension analysis of magnetic field. The computational treatments are based on the solution of field equations written down in cylindrical coordinates. This analysis is carried out using the vector potential, which is shown to be readily adaptable to the evaluation of the air-gap impedance for different disc motor constructions. The magnetic vector potential enables the effect of physical air-gap and finite permeability and conductivity of a number of machine regions to be taken into account. Using this new technique, the complex expression of the impedance can be rearranged to predict the individual equivalent circuit parameters. | ||||
