6 FAQs about [Composition of wind turbine generator stator]
Why do turbine generator stator end windings vibrate?
Turbine generator stator end windings vibrate due to electromagnetic forces generated during normal operation or under fault conditions. In normal operation, electromagnetic vibration of a stator core and the electromagnetic forces created by current flowing in stator bars excite the end windings at twice the power frequency (100 or 120 Hz).
Do stator end windings have vibration characteristics?
P.G.S. Kumar studied the vibration characteristics of stator end windings . Jiang H-C et al. comprehensively analyzed the transient EF of the turbine generator stator winding and studied the EF and mechanical response of the stator winding before and after the rotor inter-turn short-circuit fault .
Should a stator winding be connected to a series Star design?
