TL;DR: In this paper, a multiphase brushless AC electric machine with a permanent magnet is described, where the surface sections of the magnet produce a magnetic flux density having a component average amplitude B r (θ) perpendicular to the corresponding surface of the stator.
Abstract: The multiphase brushless AC electric machine comprises a stator frame having a surface provided with parallel slots and projections disposed alternately, each of the openings being substantially as wide as the widest width of the corresponding slot; and a rotor frame having a surface provided with permanent magnet means having respective surface sections facing the slots and projections. All of the surface sections of the magnet means produce a magnetic flux density having a component average amplitude B r (θ) perpendicular to the corresponding surface of the stator, which is substantially defined by the following equation: B.sub.r (θ)=M.sub.r (θ)·L.sub.a (θ)/L.sub.v (θ) where L a (θ) is defined by the following equation: ##EQU1## where θ is a position angle in radians with respect to a reference position on the rotor frame; B r (θ) is the component average amplitude at the position angle θ; L v (θ) is a gap distance between the projections and the surface of the rotor frame at the position angle θ; M r (θ) is a component of residual induction of the magnet means at the position angle θ, M r (θ) being perpendicular to the corresponding surface of the stator, M r (θ) being alternative with a period corresponding to 4π/K; K is an even number representative of all of the surface sections; and C is an arbitrary constant. The present invention is also concerned with a method of operating the multiphase brushless AC electric machine.

TL;DR: In this article, the authors presented a method to modify 5-damped response spectra for sites in eastern North America (ENA) to provide response spectrum for damping values other than 5, based on analysis of typical ENA earthquake ground-motion signals over a range of magnitudes and distances.
Abstract: National seismic hazard maps in Canada and the United States generally provide input ground motions in the form of 2%/50-year response spectra for an assumed 5% of critical damping. This paper presents a practical method to modify 5%-damped response spectra for sites in eastern North America (ENA) to provide response spectra for damping values other than 5%, based on analysis of typical ENA earthquake ground-motion signals over a range of magnitudes and distances.
