Abstract

This paper presents measured results of the two-dimensional vector magnetic properties in non-electrical steel sheets for different thickness under high frequency excitation conditions. Mars Orbiter require small size high power motor. In order to obtain its, it is necessary to rotate a motor under high-speed. However, motor efficiency reduces under high-speed rotating because magnetic properties such as field strength in motor core are changed depending on the exciting frequency. In this paper, the relationship between the magnetic flux density and field strength vector and iron loss is measured by using a vector magnetic property measurement system. Moreover, the iron losses of stator core are compared with its made of different sheet thickness under high-speed rotating.
