Hitachi Develops Higher-Efficiency Motor Technology Using Amorphous
Magnetic Metal from Subsidiary MetGlas
has applied this to a new design that it says can be economically
mass produced.
"One of the means to achieve higher efficiency in motors is the
use of amorphous metals for cores, the core loss of which is
as low as 1/10 or less that of magnetic steel sheets," said the
company. "However, amorphous metals are harder to process
than magnetic steel sheets, which has conventionally posed a
problem for productivity when they are processed into complicated shapes."

Hitachi Metals reports that it has made an important advancement in the use of amorphous magnetic metal for cost-effectively
manufacturing electric motors, a development that could bode
well for improving the energy efficiency of electric vehicles,
industrial equipment and electrical appliances.
Using specialized amorphous metal from its subsidiary Metglas
to form the motor teeth, Hitachi released data demonstrating
a four to five-fold reduction in core loss than experienced in a
comparable motor with standard magnetic steel sheet teeth - and

In the structure recently developed, Hitachi researchers focused
their efforts on a core with a low core loss that would be relatively
easy to manufacture and applied laminations of sheared Metglas
amorphous metal only to the teeth.
