| 摘要 |
The invention relates to a band attenuation/elimination filter (F) for the electromagnetic emissions of a DC motor having brushes. Said filter comprises at least one gamma filter (G) having capacitive (C1)/reactive (L1) impedance components, which is to be connected between the positive power supply input (M+) of the motor, the negative power supply input (M-) of the motor, and the negative terminal of the battery (B-). The capacitive impedance component (C1) is to be connected between the negative power supply input (M-) of the motor and the positive power supply input (M+) of the motor. A reactive impedance component (L2) is provided and is to be connected in series between the positive power supply input (M+) of the motor and the positive terminal of the battery (B+). The invention can be used for windshield-wiper motors for motor vehicles. |
