D.C. PM motor and generator with a stator core assembly formed of pressure shaped processed ferromagnetic particles

摘要: A d.c. PM motor and corresponding generator having a stator core assembly which is formed of molded or pressure shaped processed ferromagnetic particulate material. The low permeability characteristic this material accommodated for by shape optimizes the efficiency coupling field rotor into structure. Efficiency applied structure also enhanced through utilization transitions in levels between induction region each component winding support region. method described assembling assemblies using discrete pieces conjunction with back iron linking components pieces.
