  • stators with both sides of claw-shaped poles can achieve greater torque density and better power factor because the magnetic stress causing the parasitic magnetic flux between the adjacent poles is one-half smaller with the same current load.

Therefore, a simple lameli Arthur execution of the yoke made of ferromagnetic sheet metal is possible. Another advantage of a claw-shaped pole core shape on the side of the yoke is a reduction in the magnetic field in the transition region between the pole cores and the yoke. Therefore, yoke material may have smaller saturation induction than pole core material. For multi-phase stators, the yoke may be interrupted between the pole groups of different phases.
