Development of high efficient electrical rotating machines is an important issue in energy conservation. To realize this purpose, we have to consider details of magnetic phenomena in rotating machines. Therefore an accurate evaluation of the 2-D magnetic properties is indispensable. However, it is very difficult to measure these properties especially under high magnetic induction due to difficulty to measure rotating magnetic properties in the electrical steel sheets. In this paper, a new apparatus with 8-teeth-core, distributed windings, and inter-poles is proposed to measure the 2-D magnetic properties. We evaluate the uniformity of magnetic conditions in the specimen by using the finite element analysis.
