magnets are a vital part of modern life. They are found in or used to produce
almost every modern convenience today, from speakers in mobile phones to the
electric motors in hybrid cars; air conditioners and washing machines. Permanent
magnets are used increasingly in technological applications, including traveling wave tubes, Hall Effect
sensors, high temperature-resistant permanent magnets, thin-film coating equipment and flywheel storage systems.
all of these applications, it is important for the designed permanent magnet to
be of high strength, resistive to corrosion, and resistive to demagnetization
due to excessive heat. Manufacturers have
gained experience in designing and producing permanent magnets to meet these
needs for industries with permanent magnet and magnetic assembly applications.
are a number of major families of permanent magnets available for designers,
ranging from ferrite, known for its low cost and low energy, to rare earth
materials, which are more expensive and offer higher performance. Designers
need to analyze magnetizing field strength and magnetic output of magnetic
materials prior to deciding on the appropriate magnet.
magnets today are 60 times as strong as they were about 90 years ago. Strong
permanent magnets that can be used in industrial applications were developed in
the 20th century, and Japanese and western European researchers and technologies
have always played major roles in the development of permanent magnets.
the heavy reliance on Neo magnets in manufacturing, rare earth (RE) materials neodymium
and dysprosium are playing a very important role because of the scarcity of
these materials and the dominance of a single country (China) in providing
them. The permanent magnet industry will start to see the end of serious RE
shortages as new supplies begin to hit the market during 2013 and beyond, with
new designs and new materials.
STUDY GOALS AND OBJECTIVES
This iRAP report has been prepared to highlight the many new
developments in the permanent magnet industry. Many of the market segments are
mature, while others are growing at very fast rates. Developing economies such
as China and India are also emerging as growth engines for many industries that
use permanent magnets. The markets in these new economies are expected to
experience maximum revenue growth during the next five years.
Secondly, there are new
applications for permanent magnets such as voice coil motors, traveling wave
tubes, wind turbine generators, hybrid and pure electric vehicle motors, water
turbine generators, thin-film coating equipment and flywheel storage systems applications. These
have created the need for a formal analysis of technological and business
issues, trends in manufacturing, competitive landscapes and Chinese domination
in global markets, as well as factors such as shortages of raw materials used
in Neo magnets.
This report has been prepared to:

REASONS FOR DOING THE STUDY
devices, combined with the development of piezoelectric materials, have become
a key enabling technology for a wide range of industrial and consumer products.
The piezoelectric device market experienced robust growth in last two decades
and sustained fairly healthy growth even during the global economic downturns.
It will again witness strong growth in the next years, and certain application
markets already enjoy double digital growth.
industrial and manufacturing area is still the largest application market for
piezoelectric devices, followed by the automotive industry. However, the
strongest demand comes from medical instruments and information and
telecommunication, which are gaining ever-increasing importance among
piezoelectric device suppliers.
piezoelectric actuator and motor market is an attractive and still-growing
multi-million dollar market characterized by very high production volumes of
actuators and motors that must be both extremely reliable and low in cost.
Growth in the market continues to be driven by increasing demand in camera
phones for autofocus mechanisms, data storage, semiconductors,
micro-electronics production, precision mechanics, life science and medical
technology, optics, photonics, nanometrology, robots, toys, HVAC control
systems, and other applications such as piezo fuel injectors, ink cartridges in
printers, micropumps, microgrippers. microsurgery tools and piezoelectric
MEMS (piezo MEMS) actuators.
iRAP conducted this study in 2007
and later in 2009. However, with increased demand for these devices, and with
improved and emerging technologies as well as applications, iRAP felt a need to conduct a detailed
study and update technology developments and markets. The report identifies and
evaluates piezoelectric-operated actuators and motors and technologies which
show potential growth.

The permanent magnet industry
has grown in the last decade and is likely to continue this growth into the
next decade because of increased usage of magnetic circuit components in a
variety of industrial equipment and devices. Electromechanical devices
constitute the largest market for permanent magnet materials. This market is
growing rapidly. Large motors use ceramic magnets, and, for certain military
applications, samarium-cobalt (Sam-Co) is still the preferred magnet.
related to permanent magnet direct current motors – brushless direct current (BLDC)
and brush-type (PMDC) – and power generation will be the largest usage segment
of neodymium-iron-boron (NdFeB) permanent magnets, followed by voice coil
motors (VCMs) in disk drives, because of the need for reduced size and higher
performance. The third major usage segment is hybrid and electric automotive
drives. Several rare earth (RE) elements are essential ingredients in the highest
performance magnets available in the world today; these magnets have enabled
miniaturization and a significant increase in power density in hundreds of
market experienced a boom in 2011, due to increased demand for RE permanent
magnets. But as demand increased, supply chain interruptions resulted in a
scarcity of RE permanent magnets. This affected the market adversely, and it
plunged in 2012. As the supply of REs became stable, the market became stable,
and it is expected to further stabilize in the future.
permanent magnet market has a large number of small manufacturers coupled with
a few medium-sized manufacturers. The market is dominated by Chinese
manufacturers. There is a scarcity of manufacturers for rare earth magnets, and
they are geographically scattered.
