Description

<p>Recently, iron-based amorphous metals have attracted increasing attention as suitable materials for high-efficiency motors. As a preliminaly step of research, we report the results of manufacturing iron-based amorphous cores and silicon steel cores for fan motors and comparing the motor performance depending on the cores. The load test shows that the efficiency of the iron-based amorphous core exceeded the silicon steel core at each rotation speed from 1000 to 6000min-1. In particular, at 6000min-1, the efficiency was higher by 10% or more when the iron-based amorphous core was used at 0.15Nm or less. Moreover, it was shown that high efficiency can be achieved by adopting an amorphous core, and that the performance changes depending on the operating conditions.</p>
