Theory and Operation of Reluctance Motors with Magnetically Anisotropic Rotors II - Synchronous Performance

The synchronous operating characteristics of an axially laminated, magnetically anisotropic rotor reluctance motor are calculated from its physical dimensions using the two-axis approach. Modifications have been made in the ideal theory for the computation of axis-reactances to incorporate the effects arising from the practical considerations such as saturation in stator teeth iron, fringing flux and the rotor stacking factor. The validity of the analytical technique is clearly established by comparison of the predicted and measured results of a test machine which show remarkable agreement.
