The event will be held in Parabiago (Milan) at the Villa Ida Lampugnani, an historic residence of great reﬁnement, surrounded by a centuries-old park. The building preserves intact historic architecture, decorations and furnishings which make it one of the most authentic Liberty villas in Italy. Its singular and evocative setting makes it an exclusive location for events.

PM ROTORS IN-SITU MAGNETIZATION FOR POWERTRAIN MOTORS
Federico Russo, Magnetic Design | 18th September
PM Brushless motors are the first choice for electric and hybrid vehicles. One part of the motor is the inductor, which provides the magnetic field by means of series of permanent magnets. Until a couple of years ago, motor producers used to magnetize the magnets before their insertion in the rotor. Heavy industrial duty cycle, troubles in handling pre-magnetized magnets, and the effect of hot glue on pre-magnetized magnets quality all made it necessary to magnetize the entire rotors after assembly. It is known as in-situ magnetization. It comprises the magnetization, quality control, and handling automation. Here, the most recent development on EV PM rotors magnetization is described, with focus on design, development, MP equipment, and related automation systems production.
PM MAGNETIZATION MODEL FOR MIXED ANISOTROPIC AND ISOTROPIC MAGNETS
Govind Bisht, Magnetic Design | 18th September
Widely used permanent magnets are alloys made from powdered ferrite oxides or rare earth compounds. Powdered grains are milled at the desired grade, then pressed and sintered or mixed with plastic and injected. During pressing or injection, often, a strong magnetic field keeps the grains oriented to obtain anisotropic magnets. This process is not ideal: therefore, anisotropic magnets have certain percentage of isotropy associated with them. The presence of isotropy in an anisotropic magnet for what concerns the magnetization process has been described here. In addition, the modelling of such supposedly anisotropic magnet having certain isotropy level using FEA; the definition and measurement of isotropy present; along with different magnetization approaches according to the effect this isotropy ratio would have in the final application is presented here.
SHIELDING EFFECTS DURING PERMANENT MAGNETS MAGNETIZATION PROCESS
Matteo Pistaffa, Magnetic Design | 19th September
The magnetic shielding is the reduction of the magnetic field by means of a material, namely a shield. Different mechanisms are responsible for the rise of this effect, as the field can be reflected or driven through the shield, according to the frequency of the magnetic field itself. The “skin depth” of the field through the shield is the key parameter controlling the phenomenon. It depends on the frequency of the magnetic field and on the resistivity and the magnetic permeability of the material of the shield. A conscious choice of these properties allows us to exploit the effect in many applications. This work, in particular, analyzed the use of the effect to shield magnetizing inductors and, sometimes, to improve their efficiency. Then, some examples are presented, which are related to the magnetization of loudspeakers and DC motor housings, in which the permanent magnets are behind bodies that shield the magnetizing field – thus, strategies are needed to let the magnetizing field penetrate such shields.
LABORATORIO ELETTROFISICO’s 60 YEARS’ EXPERIENCE IN MAGNETIC MEASUREMENTS
Andrea Del Prete, VP of Magnetics Technology
The 60 years of Laboratorio Elettrofisico’s activities in the magnetic technology give rise to the occasion to see how magnetic measurements, standards and instrumentation followed the evolution of the materials and necessities of the industry. The wide variety of magnetic materials and their different uses demand measuring techniques to provide information that is fundamental from the beginning of the project of a magnetic device to its quality control in production. The measurement principles and modern standard techniques to measure magnetic materials are described from the point of view of the instrumentation developed by Laboratorio Elettrofisico, from the past to the present day.
