The UK's electricity consumption could be reduced by 1.6 TWh annually, equivalent to £160 million, if the average efficiency of industrial inverter-fed motors, also known as variable speed drives (VSDs), is increased by 1%. One way of achieving this, and also several other benefits such as extended lifetime, lower maintenance cost and higher reliability, ...

This project is a collaboration between Wind Technologies Limited (WT) and Cambridge University Engineering Department (CUED) and aims to study, prove and quantify the performance and economics of a new energy harvesting technology, MAGtronics, that extracts DC electricity from the leakage magnetic flux in an electrical motor. Through removing the need fo...

The project aims to study and assess the technical and commercial feasibility of a new Gate Drive technology, SmartDrive, for Power Electronics Converters (PEC) used in offshore wind turbines. SmartDrive can offer a substantial 25 and 40 percent reduction in PECs' switching losses and failure rate, respectively, hence reducing the Cost of Energy from offs...

Reliability is vital in the growth of the wind industry, especially offshore, and to realise the UK's targets for 2020. Wind Technologies has developed a novel and patent-pending condition monitoring technology, ReliaWind, with highly enhanced precision and wider range of fault prediction for wind turbine drivetrains, enabling more than 30% reduction in m...

The existing microwind (less than 2 kW) turbines in the market are expensive and the breakeven period is not attractive, more than 10 years. Almost all microwind turbines use permanent magnet generators (PMGs) in combination with a full-size power electronics converter, together accounting for 40 to 50% of the turbine cost. We have developed a new generat...

The project aims to move the Brushless Doubly-Fed Induction Generator (Brushless DFIG) technology from being a promising and proven concept, demonstrated on small scales, to an optimized industrial-scale machine for multi-megawatt wind turbine applications. The new medium-speed drivetrain concept comprising a Brushless DFIG, a fractionally rated frequency...

Wind Technologies has developed a newly configured and patented induction motor technology for use in industrial variable speed drive (VSD) applications. It offers substantial reductions, projected as high as 20%, in the system capital costs as compared to conventional VSD technologies by utilising a fractional-size converter. It hence enables a far great...
