Patent ID: 7557477

Claim:
An electric machine with integrated power electronics, the electronic machine being modularly constructed and comprising: a stator carrier ( 2 ), a power semiconductor control ( 10 ), a positive DC bar ( 4 ), a negative DC bar ( 5 ), a power semiconductor ( 8 ), and a cooling duct ( 12 ) for cooling the integrated power electronics, and the electric machine, a stator ( 1 ) and a stator winding ( 3 ), each of which is prefabricated and separately installed in the electric machine; wherein the positive DC bar ( 4 ) and the negative DC bar ( 5 ) are located so as to be essentially superimposed when radially viewed along a rotational axis and so as to be essentially parallel when axially viewed normal to the rotational axis, and an insulator ( 14 ) is situated between the positive DC bar ( 4 ) and the negative DC bar ( 5 ) with contact surfaces ( 22 A, 22 B) between the insulator ( 14 ) and the positive DC bar ( 4 ) and the negative DC bar ( 5 ) so that the insulator ( 14 ), the positive DC bar ( 4 ) and the negative DC bar ( 5 ) together comprise an intermediate circular capacitor ( 20 ) for the power electronics.
