Abstract (en)
[origin: DE102004009046B3] The operating condition diagnosis method has the voltage and current of the pump motor measured during a measuring step (30), before determination of the phase shift between the voltage and the current at spaced time points during an evaluation step (32), for provision of a phase shift characteristic, used during an association step (34) for indication of the corresponding pump operating condition (36,38,40,42). An independent claim for a device for diagnosis of the operating condition of a synchronous pump is also included.
