A new design technique based on a suitable choice of rotor geometrical parameters to maximize torque and power factor in synchronous reluctance motors. I. Theory

摘要

The influence of rotor geometry of synchronous reluctance motors (SRMs) on the x/sub d//x/sub q/ ratio, electromagnetic torque and iron losses is studied. Both air-gap length and rotor pole are are taken into account as parameters. First, a new theoretical approach is developed which neglects saturation effects (Part I). In a companion paper (Part II), a complete finite-element analysis of a particular SRM is carried out, followed by a comparison with results obtained by tests performed in a prototype machine, which was constructed in order to validate the proposed methodology.
