Abstract
The magnetic properties of a motor core deteriorate during the manufacturing process due to mechanical stresses in the materials. It is particularly hard to predict the characteristics of the slinky-laminated electrical machines, because stresses and strains occur simultaneously in the core. To examine the B-H curve and the iron loss of a core affected by the manufacturing process, a slinky-laminated surface-mounted permanent magnet synchronous motor (SPMSM) was proposed as an analysis model. The magnetic properties of the slinky-laminated core and the stacked core were compared as the results of material experiments, using the proposed motor core. With the examined material data, the iron loss of the slinky-laminated SPMSM was investigated via the finite-element method (FEM). Finally, the proposed motor was subjected to a no-load test and a mechanical loss test. Based on the test results, the actual iron loss of the motor was obtained through loss segregation and was then compared with the FEM results to verify the validity of the material experiment and loss analysis methods.
