Abstract: An electrical actuating arrangement for an internal combustion engine includes an electric drive motor disposed in a housing body. The electric drive motor includes a motor housing with a drive side closed by a plastic front plate. A mounting flange is disposed on a drive side of the electric drive motor, the mounting flange being integral with the motor housing. The plastic front plate extends at least partially radially beyond the motor housing and is configured to seat via a clamping fit in a corresponding recess of the housing body so as to radially fix the electric drive motor.
