In an electrical machine, in particular a generator for a motor vehicle, having a housing (), a rotor (), supported rotatably in the housing () about a pivot axis (), at least one fan wheel (), connected to the rotor (), for generating a cooling air flow (&#x2033;) from at least one intake opening (&#x2033;) disposed in the housing () to at least one outlet opening () disposed in the housing (), and at least one regulator chip (), disposed on a chip holder (), for regulating the current generation, it is provided that the chip holder () is disposed such that it is bathed at least in part directly by the cooling air flow (&#x2033;). As a result of this arrangement, it is attained that a very high heat transfer coefficient is present, because of the high flow speed of the cooling air flow (&#x2033;).
