Abstract
A generator, in particular of a wind power installation, for generating electric current, comprising a rotor and a stator having stator teeth and grooves arranged between said stator teeth for receiving at least one stator winding, wherein a measuring device is provided to determine the deflection of at least one stator tooth of the stator in connection with the generator, wherein the measuring device is connected to at least one measuring unit, which is embodied as a strain gauge.
Claims14
A generator for generating electric current, the generator comprising:
- a rotor;
- a stator having a plurality of stator teeth and a plurality of grooves arranged between the plurality of stator teeth, respectively, wherein the plurality of groves are configured to receive at least one stator winding;
- a strain gauge coupled between two adjacent stator teeth of the plurality of stator teeth and configured to measure a deflection, wherein the strain gauge is arranged in an air gap between the stator and the rotor;
- and
- a measuring device configured to receive a signal from the strain gauge indicative of the measured deflection.
A method for operating a generator of a wind power installation, for generating electric current, the generator comprising a rotor and a stator having stator teeth and grooves arranged between the stator teeth for receiving a stator winding, the generator including a measuring device and at least one strain gauge, the method comprising:
- operating a strain gauge to determine a deflection of at least one stator tooth of the stator in connection with the generator, the strain gauge being arranged in an air gap between the stator and the rotor of the generator;
- and
- providing measurement values indicative of the deflection to the measuring device of the at least one stator tooth.
A method for operating a wind power installation comprising:
- controlling a generator based on measurement values of one or more strain gauges, wherein the one or more strain gauges are arranged in an air gap between a stator and a rotor of the generator.
