3D Calculation of the Eddy-Current Losses in the Beam Tube of the SIS100 Dipole Magnet

چکیده
The eddy-current losses in a simplified model of the SIS100 dipole magnet (Fig. 1a) comprising the elliptical beam tube are calculated. The standard 3D Finite Element (FE) formulation is augmented by a shell element representation of the thin beam tube. Using this approach, the mesh construction can be restricted to the beam tube surface and the outer parts, avoiding the construction of elements inside the beam-tube volume. Therefore the number of unknowns of the overall numerical model is reduced. Furthermore the aspect ratio of the tetrahedra used for the discretization is improved, which leads to a better condition number of the system matrix. Therefore, the simulation time can be reduced significantly without loosing accuracy.

SIS100: For SIS100 modified versions of the fast-ramped superferric magnets of the Nuclotron synchrotron at JINR Dubna will be used. The original Nuclotron dipole magnets produce an overall AC loss at 4 K of about 38 W/m (standard cycle: Bmax=2 T, dB/dt = 4 T/s, repetition rate of 1 Hz). It is necessary to reduce the loss at cryogenic temperatures at least by a factor of 2, the corresponding R&...

In order to calculate the field quality in the aperture of the SIS100 dipole magnet, a finite element discretization based on a tetrahedral mesh is applied. An anisotropic nonlinear material model resulting from a homogenization of the laminated iron yoke is necessary to model the effects of ferromagnetic saturation [1]. The excitation current in the superconducting coils amounts to 48 kA and v...

The rotor eddy current losses of a high-speed permanent magnet synchronous motor reduce the efficiency of the motor and increase the temperature rise of the rotor. In severe cases, the permanent magnet of the rotor can be demagnetized, affecting the safe operation of the motor. In this paper, an analytical model of rotor eddy current losses calculation based on Maxwell equations is introduced. ...
