CA 2335820

An electro-mechanical machine comprising: a disc-type armature (28) being disposed in an axial airgap with respect to two stator members (30, 32); the stator members (30, 32) being provided with a plurality of permanent magnets (34) one each surface thereof; the disc-type armature (28) being provided with a plurality of coils (30) disposed on each face of the armature (28); the coils (30) are formed into at least two series connected groups (I, II). Each of the coil groups (I, II) is disposed on the surface of each of the stator members (30, 32) so that each coil (30) of one group is located between two coils (30) from another group, and the two coils (30) at one end of the interleaved groups are connected together. Power is commutated to the two coil groups at the opposite end of the group of coils (30), so the coils (30) conduct current in opposite direction.

L'invention concerne une machine électro-mécanique comprenant: une armature discoïde (28) placée dans un entrefer axial par rapport aux deux éléments formant stator (30, 32), dotés de plusieurs aimants permanents (34) sur leur surface; l'induit discoïde (28) est doté sur chaque face de plusieurs bobines (30). Les bobines (30) forment au moins deux séries de groupes connectés (I, II). Chaque groupe de bobines (I, II) est placé sur la surface de chaque élément formant stator (30, 32) de sorte que chaque bobine (30) du groupe soit placée entre deux bobines (30) d'un autre groupe, les deux bobines (30) se trouvant à une extrémité des groupes imbriqués étant connectées l'une à l'autre. L'énergie est commutée de sorte qu'elle soit envoyée aux deux groupes de bobines se trouvant au niveau de l'extrémité opposée du groupe de bobines (30) et que les bobines (30) conduisent le courant dans des sens opposés.
