Direct-drive electric machine configured with a plural-module combination structure

摘要

The present invention provides a direct-drive electric machine such as a generator and a motor comprising a rotor or a mover and a stator. The direct-drive electric machine is configured with a plural-module combination structure in which the rotor or the mover and the stator are mutually combined such that a plurality of modules form one phase, respectively.

主权项

1. A direct-drive electric machine comprising a rotor or a mover and a stator, the direct-drive electric machine configured with a plural-module combination structure in which the rotor or the mover and the stator are mutually combined such that a plurality of modules form one phase, respectively,
wherein each module of the rotor or the mover corresponds to each of magnetic poles and is installed and positioned on non-ferromagnetic material of the rotor or the mover, wherein each module of the rotor or the mover comprises:
two permanent magnets;a flux-concentrating iron core having an inverted triangular section; andtwo path-maintaining iron cores having a triangular section,wherein the each of the two permanent magnets are disposed between an inclined surface of the flux-concentrating iron core and an inclined surface of each of the two path-maintaining iron cores, andwherein the two permanent magnets, the flux-concentrating iron core, and the two path-maintaining iron cores are positioned on the non-ferromagnetic material.
