Beschreibung
Zusammenfassung:	An expansion valve for at least one of an air conditioning system, a battery cooler, and an oil cooler of a motor vehicle is disclosed. The expansion valve includes a housing, a sensor, a stepping motor or a brushless DC (BLDC) motor, a valve seat, and a valve body interacting with the valve seat. The stepping motor or the BLDC motor includes a rotor and a stator surrounding the rotor. The rotor includes a shaft and a permanent magnet body that is connected to the shaft in a rotationally fixed manner. The sensor is structured and arranged to detect at least one of an axial position and an angle of rotation of the permanent magnet body.
