  • Three-Dimensional Equivalent Magnetic Circuit Network Method for Precise and Fast Analysis of PM-Assisted Claw-Pole Synchronous Motor
    IEEE Transactions on Industry Applications, 2018
    Co-Authors: Jae-han Sim, Dong-gyun Ahn, Dooyoung Kim, Jung-pyo Hong
    Abstract:

    Permanent magnet (PM) assisted claw-pole synchronous motor (CPSM) has commonly been used in a variety of industrial applications thanks to its robust structure and high energy density. However, such a motor has an axially asymmetric rotor configuration, which induces the corresponding 3-D magnetic field distribution. Thus, this paper proposes an infinitesimal Hexahedron-Element-based 3-D equivalent magnetic circuit network (EMCN) method in order to estimate the performance of the PM-assisted CPSM. The Hexahedron Element is considered an optimum unit Element in describing the configuration of the PM-assisted CPSM in detail. That eventually makes it possible to evaluate the specific 3-D magnetic field distribution from which the flux linkage, the back-electromotive force, and the torque are also being calculated. The 3-D EMCN results are compared with 3-D finite Element analysis (FEA) data and/or experimental data to validate their accuracy. Finally, it is proved that the scalar-potential-based 3-D EMCN method requires less computing time than the vector-potential-based 3-D FEA.

Finally, it is proved that the 3-D EMCN requires a shorter computing time than the 3-D FEA.

  • Solid Elements with rotational degrees of freedom: Part II—tetrahedron Elements
    International Journal for Numerical Methods in Engineering, 1991
    Co-Authors: Shah M. Yunus, Timothy P. Pawlak, Robert D. Cook
    Abstract:

    This is the first of a two part paper on three-dimensional finite Elements with rotational degrees of freedom (DOF). Part I introduces an 8-node solid Hexahedron Element having three translational and three rotational DOF per node. The corner rotations are introduced by transformation of the midside translational DOF of a 20-node Hexahedron Element. The new Element produces a much smaller effective band width of the global system equations than does the 20-node Hexahedron Element having midside nodes. A small penalty stiffness is introduced to augment the usual Element stiffness so that no spurious zero energy modes are present. The new Element passes the patch test and demonstrates greatly improved performance over Elements of identical shape but having only translational DOF at the corner nodes.
