ELECTRIC DRIVE
First Claim
1. An electric drive having an electric motor (10) in a pot-like motor housing (14), having a gear mechanism housing (16) which is attached to the motor housing (14), and having an arrangement for radio interference suppression of the motor (10), characterized in that at least one choke coil (46, 48) for radio interference suppression is arranged in a transition region from the motor housing (14) to the gear mechanism housing (16), and in that means (36, 56) are provided in the transition region in order to shield a filtered coil end (47, 49) which projects into the gear mechanism housing (16) from the interfering radiation generated by the motor (10).

Abstract
The invention relates to an electric drive, particularly a windshield wiper drive for vehicles, comprising an electric motor (10) in a crucible-shaped, preferably metal, motor housing (14), a gearbox housing (16) that is attached to the motor housing (14), and an arrangement for the interference suppression of the motor (10). According to the invention, at least one choke coil (46, 48) for the interference suppression of the motor (10) is disposed in the transition region from the motor housing (14) to the gearbox housing (16), wherein in this transition region means (36, 56) are provided in order to shield the filtered coil end (47, 49) projecting into the gearbox housing (16) from the interfering radiation produced by the motor (10).
