Abstract

PURPOSE: To ensure the disperson of ferrite core easily and surely, by measuring the magnetic characteristics for the section layer orthogonal to the center axis of the ferrite core in a given magnetic field.
CONSTITUTION: The ferrite core 1 is set on the core set stand 11, and the center axis of the core 1 and the center of a given magnetic field caused with the magnetic field generator 9 are made in agreement by the X axis moving table 14 and the Y axis moving table 16. Further, a plurality of sensors 8 fitted to the sensor fitting tool are set internal circumference of the core 1. Moreover, the magnetic generator 9 is operated and the core 1 is turned by driving the pulse motor 20, and the magnetic characteristics at the section layer orthogonal to the center axis of the core 1 are measured with the sensor 8. Further, the core 1 measured is classified according to the amount of unbalance for the magnetic characteristics, and it is taken as parameters for winding condition.
