Abstract (en)

[origin: WO9843340A1] An electric machine according to the invention comprises a rotor means (10) and a stator means (20) surrounding the rotor means having radially extending slots (21). Slot lock components (14) are provided in at least some of said slots. The slot lock extends in said slot essentially to the periphery of the rotor bore of the stator means. The relative permeability ( mu r) and the saturated flux density of the slot lock means is essentially good. In the inventive method the density of magnetic flux effecting on the rotor means surface is made more uniform by slot lock components described above.
