Abstract

En elektrisk motor (1) med en rotor (3) og en stator (4) er vist. Rotoren (3) omfatter en rotoraksling (2) og rotorakslingen (2) holdes i et glidelager (7), fortrinnsvis med en koppformet konfigurasjon. For å tilveiebringe en elektrisk motor av den typen det spørres om, spesielt med forhøyede termiske egenskaper i området til rotoraksling glidelageret, strekker luftveier (17) seg radielt på utsiden av glidelageret (7), likevel innenfor et lagerhus (12), i retningen av rotorakslingen (2).An electric motor (1) with a rotor (3) and a stator (4) is shown. The rotor (3) comprises a rotor shaft (2) and the rotor shaft (2) is held in a plain bearing (7), preferably with a cup-shaped configuration. To provide an electric motor of the type in question, especially with elevated thermal properties in the area of the rotor shaft bearing, airways (17) extend radially on the outside of the bearing (7), yet within a bearing housing (12), in the direction of rotor shaft (2).
