Abstract
An electric machine that increases structural freedom to increase output of the electric machine while satisfying requirements of an outer shape. An armature portion includes armature cores (H, H) and a plurality of coils (CL) attached to the armature core (H). A magnetic field portion (Fs) is relatively rotatable to the armature portion and includes a plurality of magnets (Mg) and a plurality of magnetic field cores (N,S). In the magnetic field portion (Fs), the magnets (Mg) are disposed between two magnetic field cores (N,S) adjacent in a rotation direction. Each of the armature cores (H, H) includes magnetic pole groups (G, G). The magnetic pole group (G) included in the armature core (H) and the magnetic pole group (G) included in the armature core (H) constitute a magnetic pole group pair (P) that forms a magnetic path through the magnetic field portion (Fs).
