PM motor and generator with a vertical 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 a pressure-shaped processed ferromagnetic particulate material. The spaced apart isotropic core components of the stator core assembly are generally disposed in parallel relationship with the motor axis or generator axis, having a flux interaction region with a flux interaction surface located adjacent the confronting magnetic surface of a rotor and being generally coextensive with the principal dimension thereof to form an air gap. Each core component includes a winding region extending generally in parallel relationship with the device axis a field winding length to a ring-shaped back iron region. The back iron region interconnects the core components in magnetic field exchange relationship. Field windings are mounted over the core components in connection with supporting bobbins.
