- Description
- Standard double fed induction machines (DFIM) have symmetric stator - rotor side parameters when they have the same turns per phase. Additionally, the magnetising inductance looking from either the stator or rotor perspective is identical. This is not so for the Brushless Doubly Fed Reluctance Machine (BDFRM). Coupling of flux between equivalent stator and rotor windings occurs at sideband frequencies due to an air-gap flux modulation process, a consequence of differing stator winding, rotor winding and reluctance rotor pole numbers. This paper examines the modulation to explain the mutual inductance asymmetry found in experimental results.
