Patent ID: 11984776

Abstract:
A rotor (1) comprising a rotor shaft (13), a rotor core (14) having a core length, windings (12), and two impregnation rings (11), the windings (12) forming protruding windings ends (121), each one of the two impregnation rings (11) comprising an annular portion (111) and a deflector portion (112), the annular portion (111) comprising radial openings (113); and a method for impregnating the rotor (1) comprising starting a rotation of the rotor shaft (13) and impregnating the windings (12) with an impregnating agent through two nozzles respectively located upward each one of the two impregnation rings (11) and oriented towards the radial openings (113), the impregnation agent being guided by the deflector portion (112) towards the protruding windings ends (121) on both sides of the rotor (1) at a same time, in order to impregnate the windings (12) through the core length.
