and compressors demand highly efficient drives, often at
speeds above the synchronous speeds available from conventional
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 Nidec SR Drives Ltd and manufactured by Nidec SR Drives Manufacturing Ltd.
