Exceeding the Performance of Si-Fe with High End Magnetic Materials and Technologies

By Michael Weickhmann & Robert Brand | VAC
Standard motors are most often built up with electric steel, like Si-Fe alloys e.g. NO20. These alloys do possess special soft magnetic properties, which in some application may be a limiting factor, especially, when high induction or low conductivity or even high yield strength are required and the losses are under consideration. <read more>

Stability of Bonded Permanent Magnets, Is It Still an Issue?

By Thomas Schliesch, Head of Research & Development | Max Baermann GmbH

Max Baermann started to make bonded magnets in 1934 with predecessors of Alnico powder, which was mixed with Phenolic resin. Alnico and related materials were well known for their magnetic instability, until the invention of hard magnetic Ferrites in the 1950s meant a great leap forward. Nowadays Alnico has nearly completely vanished at least in Europe and a lot of efforts have been made to make materials more stable. So what is the current status? Is magnetic stability still an issue for bonded magnets? <read more>

Balancing Material Supply & Demand Within the Magnet Industry

The need for greater energy efficiency is driving changes toward smaller, lighter and energy dense devices. These have been developed predominantly using neodymium iron boron magnets. In 2010-2012 we witnessed disruption to the rare earth raw material supply that echoed through the magnet and motor industries. As we expand employment of technologies to harvest, transmit and utilize electric energy more efficiently, what will happen to the supply/demand balance.

A presentation by Steve Constantinides from Arnold Magnetic Technologies will explore current and forecasted price and availability of materials and the development of some of the more important alternate technologies (especially wind power, vehicle electrification and information storage) and discuss factors that affect the supply/demand balance.

Magnetics Market Outlook Presentations: The market track at Magnetics 2015 offers a wide range of view points and opinions on the latest factors impacting the magnetics market.
