Carbon check
July 1st 2008 ABB has launched an online
calculator that will help users
minimise the carbon footprint of
industry's largest user of electricity,
the electric motor.
The calculator shows how much
the carbon footprint can be cut
back by reducing the speed of
electric motors with variable speed
drives. The motor rating is defined
by the user. The calculator shows
the energy savings in kWh, the
monetary savings, the CO2
savings, the cost of a suitable drive
and the payback time.
Steve Ruddell, general manager,
drives and motors, at ABB,
comments "Reducing the speed of
motors with variable speed drives
can frequently save over 50% of
the energy used and in extreme
cases as much as 90%, without
any detriment to the application." More articles from ABB Ltd: |
