Abstract

L’invention concerne un moteur électrique (1) comprenant un rotor (11) monté sur un arbre (12), un stator (13) disposé autour du rotor (11), un palier avant (14) et un palier arrière (15) reliés entre eux par des moyens de fixation (21), lesdits paliers avant et arrière (14, 15) formant une cavité interne dans laquelle sont logés le rotor (11) et le stator (13), caractérisé en ce que le moteur électrique (1) comprend en outre un couvercle d’isolation phonique (20) en forme de cloche recouvrant totalement le palier arrière (15) et une partie (142) du palier avant (14) s’étendant axialement depuis une face d’extrémité (141) dudit palier avant (14), le couvercle d’isolation phonique (20) étant configuré pour amortir les bruits mécaniques et magnétiques générés par le moteur. Figure 2The invention relates to an electric motor (1) comprising a rotor (11) mounted on a shaft (12), a stator (13) arranged around the rotor (11), a front bearing (14) and a rear bearing (15). interconnected by fixing means (21), said front and rear bearings (14, 15) forming an internal cavity in which the rotor (11) and the stator (13) are housed, characterized in that the electric motor ( 1) further comprises a bell-shaped sound insulation cover (20) completely covering the rear bearing (15) and a portion (142) of the front bearing (14) extending axially from an end face (141 ) of said front bearing (14), the sound insulation cover (20) being configured to dampen mechanical and magnetic noise generated by the motor.
