Nidec's Dyneo+ Motor Brings Energy-Efficient Air Handling to Backfill Mine in
Germany
Novenco Building & Industry, a leading Danish manufacturer of
ventilation fans and systems, called on Nidec Leroy-Somer to
supply a powerful but energy efficient electrical motor for driving
the largest fan in their ZerAx range of axial fans. The system
was specially designed for extracting carbon dioxide from a
German backfill mine and needed to emphasize climate neutrality.
Now, one of Nidec's new Dyneo+ eco-efficient permanentmagnet
synchronous reluctance motors drives the giant fan.

The site is the latest
renovation project
of the Teutschenthal
backfill mine
in Germany, operated
by GTS (Grube
Teutschenthal
Sicherungs GmbH
& Co. KG). Since
the mining of potash
and rock salt was
stopped in 1982, the
mine is used to store
every year more
than 200,000 tons
of mineral waste
materials produced
by municipal and
industrial plants. By
using the cavities
Novenco delivered a 2-meter diameter fan
with efficiency up to 92%, driven by the
compact Nidec motor that combines reluctance
with permanent magnets for a power
output of 220 kW and IE5 Ultra Premium
efficiency
for the environmentally friendly and long-term safe disposal of
mineral waste 700 meters below the surface, the backfill mine
makes a significant and sustainable contribution to environmental
protection. To improve ventilation systems under the ground
intended for removing CO2 from stored mineral waste, a specially
designed 36 m tall chimney was needed with a powerful
air handling capability.
