Variable speed drives
According to International Energy Agency, electric motor systems use around half of global electricity. It is also estimated that across the UK and EU some 8bn motors are in use. For the UK it is estimated that electric motor and drive systems account for over 60 per cent of UK industrial electricity demand. In practice, a large part of this is accounted for by fans, pumps and compressors – both refrigeration and air. This makes addressing energy use in motors and drives an important topic to address.
