Abstract:

This paper presents the design and prototyping of low-cost analog circuitry to characterize the ac magnetization profile of soft magnetic materials. Soft magnetic materials prepared as ring cores are wound with equal number of turns for the primary and secondary windings. The primary winding is excited with sinusoidal supply of varying voltage amplitude. The secondary winding is interfaced with the LabView for data acquisition and calculation. Graphical plotting and viewing of the hysteresis loop exhibited by the soft magnetic materials under test can be achieved using National Instrument NI6009 data acquisition card and LabView software. This paper discusses the methods of measurement for flux density, magnetic field intensity and core permeability.

I. Introduction

Soft magnetic composites (SMCs) are a viable alternative to steel laminations for a range of new applications such as rotating machines, transformers, electronic filters, sensors and fast switching solenoids. Soft magnetic materials are central to nearly every aspect of modern electrical and electronics technology through their ability to concentrate and shape magnetic flux with great efficiency [1]. It can be employed as an efficient flux multiplier in a large variety of devices, including transformers, generators and in a wide array of apparatus from household appliances to scientific equipment.
