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).
