ELECTRICAL MACHINE ASSEMBLY Russian patent published in 2010 - IPC H02K1/27 H02K1/14 H02K21/12 

FIELD: electricity.

SUBSTANCE: according to the invention, the electrical rotation machine contains the first section of stator core, which is, essentially, of round shape and includes a number of teeth. The second section of stator core, which is also of round shape and includes a number of teeth and winding located between the first and second round sections of stator core, and rotor including a number of permanent magnets. The first section of stator core and the second section of stator core, winding and rotor are situated on the common geometrical axis. In addition, the set of teeth of the first stator core section and the second stator core section are projected in rotor direction. Besides teeth of the second stator core section are shifted in circular direction, while the permanent magnets in rotor are separated from each other in circular direction with regard to teeth of the first stator core section by pole section coming in axial direction. The poles are made from soft magnetic material. In essence, the direction of permanent magnet magnetisation is circular to direct magnet flow generated in axial pole section in circular direction and partially in axial direction when electrical machine is used with the purpose to concentrate magnet flow from the front area of adjacent permanent magnets to tooth position of the first stator core section.

EFFECT: improved working characteristics and increased efficiency factor of electrical machine.
