  • High performance linear motor and magnet assembly therefor
    Patent number: 7595571
    Abstract: A magnet assembly includes a back iron and an array of magnets. The back iron is in the form of a plate having opposed surfaces. The magnets are arranged along one of the surfaces, with the other surface being dimensioned and configured according to the magnetic field distribution associated with the magnets. The back iron geometry provides for reduced mass, reduced leakage flux, and high flux densities to improve performance of a linear motor that employs such a magnet assembly.
    Type: Grant
    Filed: November 20, 2008
    Date of Patent: September 29, 2009
    Assignee: Anorad Corporation
    Inventors: Nandakumar Thirunarayan-Kumar, James F. Smith
