Hitachi Introduces ECOHEART New Era Permanent
Magnet Motors and Drives
Hitachi
America, Ltd., Power and Industrial Division, just introduced the
new ECOHEART family of high efficiency permanent magnet motors and
drives. ECOHEART represents a new era in drives technology. ECOHEART
is targeted to OEMs, allowing them to create their own customized
drive system.
Compared with conventional standard induction motors, ECOHEART
permanent magnet technology achieves 10 percent higher efficiency
because the internal power loss is reduced by 50 percent. Also, the
volume of the motor is reduced by 50 percent and the weight by 35
percent due to high performance magnets and a new method of winding
the stator. With the sinusoidal motor current wave form developed,
instead of trapezoidal wave form which typical permanent magnet
motors employ, ECOHEART achieves low torque ripple, low vibration
and acoustic noise and much reduced harmonics.
ECOHEART Drives have no standard form factor and can be OEM unique.
In the current release, ECOHEART performance is optimized for water
pump applications and will be expanded in the future to other
application such as fans, compressors, conveyors, where more and
more energy savings and downsizing are critical.
