摘要:
An apparatus is provided comprising a flywheel (112) for storing kinetic energy and an electrical machine (190) mechanically coupled to the flywheel and arranged for conversion between mechanical and electrical energy. The apparatus is arranged for transferring energy between the flywheel and a vehicle transmission via a variable ratio transmission (182). The electrical machine is coupled to the flywheel via a disconnect clutch which comprises a magnetic coupling (116).

The invention relates to a coupling element for a magnetic gear having a coupling element for coupling magnetic flux between first and second movable members, each having an array of magnetic poles arranged thereon. The coupling element is formed from a sheet of magnetically permeable material and incorporates coupling portions and support portions integrally formed together. The coupling element sheet can be rolled into a cylindrical shape and used as the coupling element in a magnetic gear as described above. Optionally, the magnetic gear is decoupleable by virtue of the coupling element being arranged such that an external magnetic field can be selectably applied to it, thereby causing saturation and resultingly substantially preventing coupling of magnetic flux between the first and second members.

The present invention relates to the mounting of magnet coils as used in Nuclear Magnetic Resonance systems. In particular, the mounting scheme is relevant to gradient magnet assembly of such systems. Using the present invention hard contact between gradient magnet assembly and a cryostat does not occur. This allows a reduction in the transmission of mechanical vibrations and any resultant disturbance. Furthermore vibration of the gradient magnet assembly is reduced enabling improved system performances.
