In a method for determining a thickness of a layer of electromagnetically conductive material, the measurement errors resulting from different quality of the basic material are eliminated. For each basic material, one dimensionless characteristic value (K) is ascertained. With the aid of a characteristic calibration curve, each characteristic value (K) can be assigned a correction factor (F), with which the measured value of the layer thickness (D ) can be converted into a real value of the layer thickness (D). Different electrical and magnetic properties, dictated by the different quality of the basic material, can thus be largely eliminated.

The invention relates to a fuel delivery unit, having a side channel pump that in a housing ( ) has a pump chamber ( ) and in the pump chamber ( ) has an impeller ( ), and having an electric motor ( ) that drives the impeller ( ) and has a stator and a rotor ( ). The impeller ( ) of the fuel delivery unit is the rotor ( ) of an asynchronous motor. The electric motor ( ) can be assembled from only a few, highly reliable and strong components.

Fuel delivery system

A delivery unit for motor fuel includes a side channel pump and an electric motor that drives the side channel pump. The electric motor has an armature winding, a permanent magnet (,), and a rotor (,). The rotor (,) and the impeller (,) of the side channel pump are a single component, and the permanent magnet (,) is inserted with positive engagement into a circumference (,) of this component. This allows the production of an especially low-height, low-leakage side channel pump.

Fuel delivery unit

The motor fuel delivery unit for delivering motor fuel includes a delivery pump (,) and an electric motor (,) for driving the delivery pump (,). The delivery pump (,) includes a housing (,) provided with a pump chamber (,) and an impeller wheel (,) arranged in the pump chamber (,). The electric motor (,) includes a stator (,) provided with an armature winding (,) and a rotor (,) provided with permanent magnets (,). The electric motor (,) is brushless and consists of the impeller wheel (,) of the delivery pump (,). The stator (,) has an inner ring face consisting of a peripheral wall (,) of the pump chamber (,).

Motor fuel delivery unit

A process for determining a thickness of a layer of electrically conductive material, any measurement errors are converted into dimensionless norm values with the aid of a normalization process. In this conversion, measurement errors, for example due to temperature drift and different electrical and magnetic properties of the base material of the carrying body can be largely eliminated. These norm values are converted into layer thickness values with the aid of a calibration curve.

A multi-stage side-channel pump (,) in particular for fuel for a motor vehicle, having at least first blade chambers (,) of a precursor stage (,) and second blade chambers (,) of a main stage (,). The side-channel pump (,) has an electric motor (,) for driving an impeller (,). The electric motor (,) has a rotor (,) and a stator (,). The first blade chambers (,) of the precursor stage (,) and the second blade chambers,of the main stage (,) are integrated with the impeller (,). The impeller (,) can also form the rotor (,), making it possible to produce an extremely shallow side-channel pump (,). This pump is employed preferably for fuel delivery in gasoline injection to an internal combustion engine.

The flow pump for supplying a fuel in a motor vehicle includes a pump housing (10) provided with a pump chamber (11) bounded by two radially-extending side walls (12,13) axially spaced from each other and connected with each other by a peripheral wall (14) and a rotatable impeller (24) arranged in the pump chamber (11) coaxial to a pump axis (22). The impeller (24) includes circumferentially spaced radial impeller blades (29) bounding axially open impeller chambers (31) and an outer ring (30) connecting the impeller blades (29) with each other. The two radially-extending side walls (12,13) are provided with respective groove-like side channels (20,21) concentric to the pump axis (22) and open to the pump chamber (11). Each radially-extending side wall (12,13) has an intervening portion (23) between a channel end (212) and a channel beginning (211). The outer ring (30) and the peripheral wall (14) bound a radial space (32,32') between them and the outer ring (30) includes a circumferential radial gap (34) or a plurality of throughgoing passages (37) for providing a fluid flow between a number, advantageously all, of the impeller chambers (31) and the radial space (32,32').
