Electromagnetic Behavior

Dual laminated core models for determining exciting power (or/and specific total iron loss) and over saturation characteristics occurred at joints and silicon steel sheet was proposed and prototyped. Calculation method of exciting power at joints of transformer was presented. The saturation characteristics of laminated silicon steel sheets was obtained and analyzed. The model also can be used to investigate the relevant electromagnetic behavior of laminated core in detail.

Processing Stress

The motor core including a rotor core and a stator core, which is made from silicon steel sheets. Iron loss increases during fixation of the stator core, e.g., by interlocking, welding, and shrink fitting installation. In this paper, the magnetic properties changes by each processing such as wire cutting, punching, interlocking and shrink fitting are investigated. Iron loss of the toroidal cores using punching, interlocking and shrink fitting are increased from 1.16 W/kg to 1.56 W/kg (34.4 % increased) at 50Hz, and from 21.1 W/kg to 27.5 W/kg (30.3 % increased) at 400 Hz compared with iron loss of wire cut toroidal core.
