Provided is a stator device for an electric flat motor, including a first stator side part and a second stator side part which can be arranged in such a way that a gap is formed between the first stator side part and the second stator side part to accommodate a rotor, the first stator side part includes an electrically insulating carrier substrate with an electrically conductive conductor layer arranged thereon, and wherein coil-like conductor tracks are formed in the conductor layer. The stator device includes a stiffening device for stiffening the first stator side part, wherein the stiffening device is designed as a magnetic inference for the first stator side part. Furthermore, provided is an electric flat motor for a quick adjustment device for a motor vehicle and a method for producing a stator device for an electric flat motor.
