Saves energy cooling costs
16 December 2013
The Science and Technology Facilities Council (STFC) is saving a significant amount on its energy costs after fitting three ABB-Baldor direct drive cooling tower motor and drive systems to the cooling towers of the ISIS neutron source’s proton accelerator.

The ABB-Baldor system incorporates a permanent magnet (PM) motor. These are a viable alternative to conventional AC induction motors and deliver significant energy efficiency advantages, even compared with the latest premium-efficiency types of motors.
This higher efficiency is even more pronounced when run at low frequencies which is the case for these direct drive cooling tower motors.
