An electric motor includes a stator ( 3 ) secured in the motor housing ( 2 ), a rotatable rotor ( 4 ), a fan impeller ( 5 ) arranged on the rotor ( 4 ), and an annular air duct ( 6 ) arranged between the fan impeller ( 5 ) and the rotor ( 4 ) and having a shroud ( 7 ) spaced from the impeller ( 5 ) by a slot having an axial width (X), a dimensionally stable, with respect to the shroud ( 7 ), housing stop ( 8 ), an axially, resiliently displaceable fixing element ( 9 ) forming a stator stop ( 10 ) facing in a same direction as the housing stop ( 8 ), and a locking element.
