You are welcome to attend on September 25 at 12:40,  during the World Magnetic Conference 2019, in the topic section T7 Technologies and systems the technical speech on:

FAST ANALYTICAL METHODS FOR MAGNETIZATION FIXTURES DESIGN AND OPTIMIZATIONS.
presented by Ing. Stefano Tizianel, R&D Director.

Abstract

Permanent magnets often are assembled in the devices before being magnetized “in-situ”.
This industrial approach makes the design of magnetization fixture much more complicated than the one of a simple solenoid. Being that the magnetization performances need to be optimized as much as possible, and that in the design, hundreds of parameters, physical, geometrical and economical are involved, 1D analysis is frequently exploited as the fastest optimization tool, and FEA is used as verification tool after the design has been optimized.
1D analysis uses a lot of analytical formulas instead of solving thousands of equations like in the 3D FE environment. After the definition of systems design targets, concept of saturation, knock down, demagnetization, accuracy, resolution and forces involved in permanent magnet magnetization, a comparison between analytical calculations and FEA is presented.
Straightforward and optimization strategies are described. Some example will be reported, e.g. the influence that skin depth, fixture geometrical and physical dimensions, materials specs, capacitance, voltage, currents have on the magnetization fixtures efficiency.
