Surge arrester for a an electric machine, comprising a dummy component ( 2 ) which is, compared to components on a circuit board ( 1 ) of the electric machine, mounted at the shortest distance from a discharge element ( 4 ) of the electric machine, the dummy component ( 2 ) being connected to earth potential in at least one terminal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A surge arrester for an electric machine, comprising a dummy component ( 2 ) which is, compared to components including a sensor element ( 3 ) on a circuit board ( 1 ) of the electric machine, the dummy component mounted at a shortest distance from a rotatable shaft ( 4 ) that acts as a discharge element of the electric machine, the dummy component ( 2 ) being connected to earth potential at all electric terminals thereof. 2. The surge arrester according to claim 1 , characterized in that the dummy component ( 2 ) is disposed on the circuit board ( 1 ) of the electric machine. 3. The surge arrester according to claim 2 , characterized in that the dummy component ( 2 ) projects above all other components on the circuit board ( 1 ) toward the rotatable shaft. 4. The surge arrester according to claim 2 , characterized in that the dummy component ( 2 ) is present in a parts list of the circuit board ( 1 ). 5. The surge arrester according to claim 2 , characterized in that an earth lead on the circuit board ( 1 ) is disposed such that said lead forms as short a path as possible on the circuit board ( 1 ). 6. The surge arrester according to claim 1 , characterized in that the dummy component ( 2 ) is a ceramic capacitor. 7. The surge arrester according to claim 1 , characterized in that the dummy component ( 2 ) is an electrical resistor. 8. The surge arrester according to claim 1 , characterized in that the dummy component ( 2 ) is a contacting pin. 9. An electric machine comprising a circuit board, a rotatable shaft that acts as a discharge element and a surge arrestor including a dummy component ( 2 ) which is, compared to components including a sensor element ( 3 ) on the circuit board ( 1 ), mounted at a shortest distance from the rotatable shaft ( 4 ), the dummy component ( 2 ) being connected to earth potential at all electric terminals. 10. The electric machine according to claim 9 , characterized in that the dummy component ( 2 ) is disposed on the circuit board ( 1 ) of the electric machine. 11. The electric machine according to claim 10 , characterized in that the dummy component ( 2 ) projects above all other components on the circuit board ( 1 ) toward the rotatable shaft. 12. The electric machine according to claim 10 , characterized in that the dummy component ( 2 ) is present in a parts list of the circuit board ( 1 ). 13. The electric machine according to claim 10 , characterized in that an earth lead on the circuit board ( 1 ) is disposed such that said lead forms as short a path as possible on the circuit board ( 1 ). 14. The electric machine according to claim 9 , characterized in that the dummy component ( 2 ) is a ceramic capacitor. 15. The electric machine according to claim 9 , characterized in that the dummy component ( 2 ) is an electrical resistor. 16. The electric machine according to claim 9 , characterized in that the dummy component ( 2 ) is a contacting pin.
