Interference suppression module for an electrically commutated electric motor, method for producing an interference suppression module, and vehicle comprising such an interference suppression module

1. An interference suppression module, in combination with an electrically commutated electric motor of a transmission of a vehicle and a control unit of the electrically commutated electric motor, the interference suppression module comprising:

a circuit carrier;

an electronic circuit arrangement disposed on said circuit carrier;

an encapsulation encasing said electronic circuit arrangement with a form-fit and in a material bond; and

at least one interface electrically connecting said electronic circuit arrangement to the control unit of the electrically commutated electric motor of the transmission of the vehicle, said at least one interface being a plug module including at least one electrical contact pin and a further encapsulation encasing said at least one electrical contact pin with a form-fit and with a material bond, wherein said further encapsulation is separate from said encapsulation, and wherein the control unit is separate from said interference suppression module and is electrically connected to said circuit carrier by said at least one electrical contact pin of said at least one interface.

2. The interference suppression module according to claim 1 , wherein said at least one interface is a lead frame.

3. The interference suppression module according to claim 1 , wherein said at least one interface comprises an exposed contact surface that is electrically connected to said electronic circuit arrangement by way of an electrical line element integrated into said circuit carrier.

4. The interference suppression module according to claim 1 , wherein said electronic circuit arrangement is connected to said circuit carrier in a material bond.

5. The interference suppression module according to claim 4 , wherein said electronic circuit arrangement has at least one capacitor.

6. The interference suppression module according to claim 5 , wherein said at least one capacitor is an electrolytic capacitor.

7. The interference suppression module according to claim 1 , wherein said encapsulation does not cover said further encapsulation.
