This test system can apply to two kinds of measurements . one is the automatic measurement of the core loss for the different core of the same type under the same amplitude of the magnetic flux density ; the other is the automatic measurement of the alternate magnetization curve and the core loss curve for the core 本测试系统主要进行以下两方面的测试，一是在同一个b _ m下对同一型号的不同电机铁芯进行铁损测试；二是对电机铁芯的交流磁化曲线和铁损曲线的自动测试。
