Carbon check
August 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 Limited: |
