Abstract
An electrical machine (10) includes a rotor (12) and a stator (11) arranged within a machine housing (23) which are cooled by at least one cooling circuit (16A, 16B). The machine (10) further includes 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 a cooling device (19, . . . , 21). A flexible arrangement and cooling of the electronic power device (18) is achieved by providing a cooling device (19, . . . , 21) for the electronic power device (18) which is independent of the at least one cooling circuit (16A, 16B) of the rotor (12)and the stator (11).
