Electrical drives lie at the heart of most industrial processes and
make a major contribution to the comfort and high quality products
we all take for granted. They provide the controller power needed
at all levels, from megawatts in cement production to milliwatts in
wrist watches. Other examples are legion, from the domestic kitchen
to public utilities. The modern electrical drive is a complex item,
comprising a controller, a static converter and an electrical
motor. Some can be programmed by the user. Some can communicate
with other drives. Semiconductor switches have improved,
intelligent power modules have been introduced, all of which means
that control techniques can be used now that were unimaginable a
decade ago. Nor has the motor side stood still: high-energy
permanent magnets, semiconductor switched reluctance motors,
silicon micromotor technology, and soft magnetic materials produced
by powder technology are all revolutionising the industry. But the
electric drive is an enabling technology, so the revolution is
rippling throughout the whole of industry.
