An electric motor comprises: an outer casing (2) formed by a substantially cup-shaped part or container (3) and by at least one lid (4, 4a); a stator unit (5) and a rotary unit (6), comprising a shaft (7) partly coming out of the casing (2), housed in the casing; at least a bearing (9, 10) operating between the rotary unit (6) and the casing (2) to rotatably constrain the shaft (7) to the casing (2), the casing (2) having a cavity (9a) for the bearing (9, 10); power supply means (11) for the stator unit (5) or the rotary unit (6) inserted in the casing (2); sealing means (13, 30) positioned between the lid (4, 4a) and the substantially cup-shaped part (3); the electric motor comprises an annular gasket (15, 17) positioned in a cavity (14, 16) between the shaft (7) and the bearing (9, 10). |
