Description

This paper presents development of an industrial motor with an amorphous winding core for large capacity applications. The motor is developed for establishing proper motor designs to apply amorphous cores to large capacity motors. The motor design and the test results of a trial motor are discussed in this paper. In this research, we targeted the development of a motor which has IE4 efficiency with half the size of the previous motor. It was confirmed by the tests of the trial motor that the development targets can be surpassed by the design of obtaining higher output at high efficiency and the design of decreasing iron loss and copper loss. Comparing of the current motors for industrial motor, this motor obtained a much higher efficiency, which demonstrated the low loss amorphous core stator can contribute to high efficiency.
