Abstract

This paper presents core loss evaluation of turbine generator model stator. The stator configuration does not make magnetic flux distribution uniform, and the induction harmonics make the core loss calculation difficult. In this evaluation, the core losses are measured by rotating stator torque.
As a result of the measurements, a half-lap-stacked stator obtains lower core losses and larger percentage of eddy current losses than a block-stacked stator. In addition, a gap between each segment makes in-plane eddy current loss increase.
