The magnetic properties of a motor core are deteriorated by slinky lamination method due to the mechanical stress and strain in core materials. To analyze the iron loss of an electrical machine with a slinky-laminated stator, material experiments using the stator core were conducted. With the examined material data, the iron loss of the proposed motor was investigated using the finite-element method (FEM). To verify the validity of the material experiment and FEM, the proposed motor was subjected to a no-load test and a mechanical loss test. Based on the test results and through the loss decomposition process, the actual iron loss of the motor was obtained and was compared with the FEM results.
