Newton Derby provide special high speed AC and DC generators typically up to 8000rpm, PMGs & Exciters for large generators at various speeds and high frequency generators typically 125-400Hz at speeds up to 3000rpm.
Newton Derby has also manufactured prototypes for developments in permanent magnet generation for novel types of wind, tidal and oil pipeline generation. Details of such designs are currently confidential, but they bring key cost and performance advantages over conventional generators to turbine manufacturers, such as greater reliability due to fewer moving parts, lower weight, zero cogging torque, higher efficiency at partial load, lower predicted O&M costs and higher availability due to inherent redundancy, along with manufacturing, assembly and installation benefits. These benefits directly contribute to lower electricity costs.
Newton Derby prides itself on adding value to innovative developments within the power generation sector.
