Abstract
A method for manufacturing a stator of an electrical rotating machine that is configured to have a rotor mounted inside the stator. The stator has a laminated magnetic circuit having a stack of magnetic metal sheets disposed substantially parallel to a plane perpendicular to the axis of rotation of the rotor of the machine. The magnetic circuit has teeth that delimit longitudinally oriented slots. The method includes the step of installing electrically conductive wires in the slots and forming winding heads at the two axial ends of the magnetic circuit and installing this assembly on a vertical axis. The assembly is trapped between an outer sheath, forming part of the final motor, and a removable inner core substantially occupying a volume reserved for the rotor. The conductive wires in the slots are impregnated under vacuum with a slot-impregnating composition including a heat-setting resin and a filler, and the composition is polymerized.
