Our technologies address some of the world’s most pressing challenges, including reducing reliance on Rare Earth Elements, supporting the roll-out of the clean hydrogen economy and facilitating the development of the fuel cell and distributed energy markets.

As part of our growth strategy Time To ACT plc supports the global transition to Net Zero through the development and commercialisation of world-beating clean technologies.

Rare Earth-Free Permanent Magnet Generator (PMG)

The GreenSpur generator is a game-changing, cost-efficient solution, which addresses the critical materials risk facing the renewable energy sector.

The GreenSpur team have developed a highly innovative, axial flux, Rare Earth-free, permanent magnet generator (PMG). It incorporates multiple innovations, which make the use of ferrite magnets possible. It also uses patented aluminium coils to replace the copper windings used within existing generators and composite materials to aid lightweighting.

GreenSpur’s generator design is based around an axial-flux architecture, as opposed to the radial-flux architecture used in most motors and generators and the direct drive generators used in offshore wind turbines. In conventional, radial-flux generators, the rotor (rotating part of the generator) and stator (stationary part) are concentric cylinders, with magnetic flux flowing between them. The flux lines flow to and away from the axis of rotation of the generator. In an axial-flux generator, the rotor and stator are arranged as discs along the axis of the machine, and the magnetic flux flows parallel to this axis as “axial lines”.

The GreenSpur Rare Earth-free, permanent magnet generator (PMG) is applicable for:

  • Horizontal Axis Wind Turbines (offshore)
  • Vertical Axis Wind Turbines (onshore)
  • Vertical Axis Wind Turbines (offshore)
  • Tidal Turbines
  • Wave Turbines
  • Marine Turbines
