Abstract:
An electric machine, especially a transversal flux machine, the stator being composed of a stack of phase segments, each phase segment having at least one stator segment and one stator winding, especially a single winding, each stator segment having an annular stator bridge, on which pole shoes are premolded, which in particular extend radially inward, and/or which extend in the direction of the rotor and/or which are situated between the rotor and the annular stator bridge, the pole shoes having the same shape, in particular, the axial width of the pole shoe decreasing with increasing radial clearance, the associated profile being disposed between a first and a second profile, the first profile being a linear function of the radial clearance, the pole back associated with the first profile being a planar area, in particular, the second profile being a circular function, in particular a circular segment function, the pole back associated with the second profile being a cylindrical section area, in particular.
