Abstract [en]

This paper presents a 2-D design of a measurement setup that subjects laminated steel to field conditions corresponding to the ones of the rotor in a Salient Pole Synchronous Machine (SPSM). This stationary setup exposes the test samples to traveling magnetic waves in an air-gap. The purpose of this setup is to simulate the eddy current losses that result from high frequency magnetic fields within the volume of the test samples. The investigation of the design and the dimensioning of the model is conducted in a 2-D Finite Element Method (FEM) model. The study shows that it is possible to emulate traveling sinusoidal magnetic flux in the air-gap of a setup excluding motion. A rectangular shape of the setup was chosen due to the expected flexibility of the design as well as easy manufacturing. It was found that in order to achieve a constant amplitude of the traveling wave in the air-gap an implementation of an auxiliary winding is an effective solution.
