  • Publication number: 20200177062
    Abstract: We describe a method of manufacturing a stator of an axial flux permanent magnet machine, the machine having a stator comprising a stator housing defining a chamber comprising a set of coils wound on respective stator bars and disposed circumferentially at intervals about an axis of the machine, and a rotor bearing a set of permanent magnets and mounted for rotation about said axis, and wherein said rotor and stator are spaced apart along said axis to define a gap therebetween in which magnetic flux in the machine is generally in an axial direction, the method comprising: providing first and second radial walls for said stator housing; providing inner and outer side walls for said stator housing; assembling said first and second radial walls and said inner and outer side walls around said set of coils to form a stator assembly, wherein said assembling further comprises: providing one or more collapsible elements between said side walls and one or both of said first and second radial walls; and attaching said

  • Patent number: 10069388
    Abstract: We describe a method of manufacturing a housing for the stator of an axial flux permanent magnet machine, the machine having a stator comprising a set of coils wound on respective stator bars and disposed circumferentially at intervals about an axis of the machine, and a rotor bearing a set of permanent magnets and mounted for rotation about said axis, and wherein said rotor and stator are spaced apart along said axis to define a gap therebetween in which magnetic flux in the machine is generally in an axial direction, the method comprising: fabricating a radial wall for said stator housing to be located in said gap between said rotor and said stator by: placing a resin membrane into a mold of an injection molding machine; injection molding a set of reinforcing features onto said membrane using a thermoplastic polymer bondable when molten with said resin; and manufacturing said housing using said radial wall.

  • Patent number: 9849151
    Abstract: A Salacia composition described herein significantly reduces appetite, activates Hormone Sensitive Lipase, and manages a healthy lipid profile through inhibition of HMG-CoA Reductase enzyme. Salacia compositions described herein include of at least 12% of polyphenols, 2% of mangiferin and 1% of 25,26-oxidofriedelane-1,3-dione by weight of the composition in the form of extract. The composition is obtained by continuous solvent extraction, employing non-aqueous food grade solvents. Salacia compositions herein reduce appetite by about 18% of routine diet, when effective amounts are administered to a subject in need thereof. Effective management of a healthy lipid profile is thus possible with synergistic combination of reduction in energy intake, activation of Hormone Sensitive Lipase, and inhibition of HMG-CoA Reductase enzyme responsible for cholesterol metabolism.
