Torque Enhancement of Surface-Mounted Permanent Magnet Machine Using Third-Order Harmonic

Wang, K.; Zhu, Z.Q.; Ombach, G. Magnetics, IEEE Transactions on, 2014

This work presents a permanent magnet (PM) shaping technique with optimal third harmonic to improve the output torque without deteriorating the torque ripple in surface-mounted PM (SPM) machines. The optimal value of third harmonic injected into the sinusoidal PM shape for maximum torque improvement is analytically derived and confirmed by finite-element analysis. Further, the influence of magnet edge thickness on ...


Computerized magnetic test and evaluation of hysteretic materials [hysteresis motors]

Jowett, P.T.; MacInnes, D.I. Industry Applications Society Annual Meeting, 1989., Conference Record of the 1989 IEEE, 1989

Techniques are described which enable highly nonlinear hysteretic materials to be fully characterized. Major hysteresis loops and minor trajectories are presented for one particular material sample. Test time is reduced to less than 10s, ensuring that heating effects in the ring sample are negligible. The method is appropriate for detailed material investigation for design or development applications. It is recognized, ...

Clad periodic permanent magnet structures for electron-beam guidance

Leupold, H.A.; Clarke, J.P.; Lockwood, W.E.; Meyers, D.J. Electron Devices Meeting, 1986 International, 1986

Permanent magnet structures are described in which the longitudinally oriented flux supply magnets of a conventional periodic structure are clad with radially oriented toroidal magnets shaped to confine the flux to the working space of the stack bore. Such cladding increases the useful magnetic field in the working space and eliminates potentially deleterious stray fields outside of the structure. Alternatively, ...
