Abstract
An electrical, rotary machine may include a first stator core section being substantially circular and including a plurality of teeth, a second stator core section being substantially circular and including a plurality of teeth, a coil arranged between the first and second circular stator core sections, and a rotor including a plurality of permanent magnets. The first stator core section, the second stator core section, the coil and the rotor are encircling a common geometric axis, and the plurality of teeth of the first stator core section and the second stator core section are arranged to protrude towards the rotor. Additionally the teeth of the second stator core section are circumferentially displaced in relation to the teeth of the first stator core section, and the permanent magnets in the rotor are separated in the circumferential direction from each other by axially extending pole sections made from soft magnetic material.
