| 摘要 |
The invention relates to an electric machine comprising a stator, said stator comprising a packet (10) of magnetic sheets made up of at least one first sub-packet (50) and at least one second sub-packet (60) adjacent to the first sub-packet, the sheets of the first and second sub-packets having overlapping portions, which each comprise at least one closed channel formed within the sheets, the sheets being identical but angularly offset relative to one another by an angle 360°/n about the axis of the machine, where n is an integer other than zero, the sheets being asymmetrical by a rotation of 360°/n so that the portions of the sheets thus offset that overlap are not identical and create said disruption of the flow at the transition between the channels of the first and second sub-packets. |
