Patent ID: 6897583

Claim:
An electrical machine in the form of a generator for a motor vehicle, comprising: a housing ( 2 ); a rotor ( 6 ), supported rotatably in the housing ( 2 ) about a pivot axis ( 5 ); at least one fan ( 20 ), connected to the rotor ( 6 ), for generating a cooling air flow ( 22 ″) from at least one intake opening ( 37 ″) disposed in the housing ( 2 ) to at least one outlet opening ( 24 ) disposed in the housing ( 2 ); and at least one regulator chip ( 31 ), directly disposed on a chip holder ( 30 ), for regulating the current generation, wherein the chip holder ( 30 ) is disposed such that it is bathed at least in part directly by the cooling air flow ( 22 ″), is received in a recess ( 26 ) in the housing ( 2 ), and is thermally insulated by a thermal insulation ( 33 ″) from the housing ( 2 ), wherein the at least one intake opening ( 37 ″) in the housing ( 2 ) disposed immediately adjacent the chip holder ( 30 ) in the housing ( 2 ), so that waste heat from the chip holder ( 30 ) is already dissipated in the intake opening ( 37 ″).
