Electric motor with an air duct

Abstract

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.

Dependencies are inferred from the claim text.
