Abstract

See full text

A method for continuous operation of a rotating machine, the method is performed in a rotating machine having an inner stator and an outer stator. The method includes setting a rotating machine reference operational value for the whole rotating machine, obtaining operational parameters for the inner stator and for the outer stator, wherein the operational parameters include magnetic cross-coupling between the inner and outer stators, determining an inner stator reference operational value for the inner stator and an outer stator reference operational value for the outer stator based on the set rotating machine reference operational value for the whole rotating machine and the obtained operational parameters, and driving the rotating machine based on the determined inner stator reference operational value for the inner stator and on the determined outer stator reference operational value for the outer stator, wherein the determined inner stator reference operational value for the inner stator differs from the determined outer stator reference operational value for the outer stator.
