Pumps and compressors demand highly efficient drives, often at speeds above the synchronous speeds available from conventional motors. 

SR Drive^® systems not only deliver very high system efficiency but are also able to maintain this high efficiency over the full operating range of most pumps and compressors.  In some cases the high operating speeds available from SR Drive^® systems enables the motor to be direct-coupled to the final application, removing the need for speed-increasing gears or belts and their associated set-up and maintenance.  Precise variable-speed control eliminates the need for inefficient bypass systems, enabling dramatic reductions in operating costs.

There are thousands of pumps and compressors in use worldwide powered by drive systems developed by Switched Reluctance Drives Ltd and manufactured by SR Drives Manufacturing Ltd.
