Saving energy
04 March 2013
What is said to be worlds first IE4 synchronous reluctance motor and drive package (SynRM) from ABB has replaced an induction motorbased variable-speed drive package at South Staffs Water, resulting in an additional 6% energy saving.
What is said to be world's first IE4
synchronous reluctance motor and
drive package (SynRM) from ABB
has replaced an induction motorbased
variable-speed drive package at
South Staffs Water, resulting in an
additional 6% energy saving.
The installation meant removing the existing drive and replacing it with an ABB drive, ACS850, featuring a more powerful core processor that enables operation with the synchron - ous reluctance motor along with the next generation direct torque control (DTC), which avoids the need for encoders and speed feedback devices.
The SynRM has also resulted in a 75% reduction in audible noise: down from 78 to 72.3dBA when running at 1450rpm.
