Abstract:
An electrical rotating machine comprising an external stator and a rotor having a geometrical axis of rotation and disposed inside the stator, said stator embodying a laminated magnetic circuit comprising:an axial stack of yokes, each yoke being made from a magnetic metal sheet and being disposed substantially parallel to a plane perpendicular to the axis, the stack forming an external covering; a plurality of teeth disposed inside the covering, protruding radially towards the inside, the teeth each being made from a magnetic metal sheet and disposed substantially parallel to a plane perpendicular to the axis, the teeth being axially stacked and the stacks of teeth axially-extending delimiting slots, the teeth being bound to the covering; the slots being delimited on the radially outer side by the yokes, the slots being delimited in the circumferential direction by the side walls of the teeth, electrically conductive wires being disposed in the slots, and wherein the covering is mounted such that it is bound to a sheath surrounding the covering on the outside thereof, a circuit for a cooling liquid being provided in said sheath.
