Patent ID: 7466058

Claim:
A transverse flux electrical machine comprising: a first element having an axis and magnets disposed along said first element at a uniform radial distance from said axis, angularly adjacent ones of said magnets having magnetic polarizations of opposite directions; and a second element concentrically mounted to said first element for relative rotation to one another, said first and said second elements being radially spaced with an air gap, said second element having: a plurality of magnetic cores annularly disposed along said second element, each one of said cores comprising: a U-shaped part comprising an end segment substantially parallel to said axis and two radially extending arm segments, said arm segments being substantially angularly aligned from one another, said U-shaped part defining an interior area and an open side and being disposed such that said open side faces said air gap; a first magnetic foot assembled to an end of one of said arm segments such that said first magnetic foot is contiguous to said air gap to provide a first magnetic pole, said first magnetic foot and said U-shaped part being made of different materials; a second magnetic pole at an end of the other one of said arm segments and contiguous to said air gap; and wherein said first magnetic foot is shaped such that it deviates a magnetic flux circulating in said U-shaped part so that said first magnetic pole and said second magnetic pole are angularly offset from one another with respect to said axis; and an electrical conductor coil disposed in said interior area of all of the U-shaped parts.
