Abstract
The invention relates to an electrical machine (10) with a rotor (12) and a stator (11) arranged within a machine housing (23), and which are cooled by at least one cooling circuit (16A, 16B). The machine (10) further comprises power semiconductors which constitute part of an electronic power device (18) associated with the machine (10), and which are arranged within the machine housing (23) and are cooled by cooling means (19, . . . , 21). A flexible arrangement and cooling of the electronic power device (18) is achieved by providing cooling means (19, . . . , 21) for the electronic power device (18) which are independent of the at least one cooling circuit (16A, 16B) of the rotor (12) and the stator (11).
