Coupled Analysis Subcycling

  • A much greater degree of freedom for coupled analysis timing in JMAG!
    • Choose either magnetic field or thermal analysis as time standard for coupled analysis
    • Choose multiple studies in slave analysis

Coupled Analysis Subcycling

Multi-frequency Heating

  • Account for multiple frequencies in coupled magnetic field thermal analysis!
    • Estimation of dual wave properties in high-frequency induction heating
    • Respective losses from different superimposed frequencies can be analyzed by specifying multiple magnetic field analysis (FQ) files

Coil-end Cooling Component, Rotating Copies of Contact Resistance and Isothermal Boundary Conditions

Parametric analysis of the number of slots is now supported for coil-end cooling components. Different cooling methods such as ATF can be specified in the circumferential direction.
In rotating copy of contact resistance and isothermal boundary conditions, in addition to reducing the setting time for multi-pole multi-slot, parametric analysis of the number of poles and slots is now supported.

Magnetrostriction Analysis of a Reactor

Eigenvalue Analysis

Vibration/noise is caused by the resonance phenomena of excitation force and eigenmode vibration.
With JMAG’s structural analysis, eigenvalue and eigen vector can be obtained.

Example: Eigenvalue may change if static stress due to shrink fitting or press fitting is applied. Running eigenmode analysis accounting for stress distribution obtained in stress analysis allows for obtaining the eigenvalue accounting for these effects.

Sound Analysis

Example: Motors are widely used in various applications that require smaller and lighter motors along with the reduction of vibration and noise. JMAG can be used to analyze vibration and radiation sound caused by slot harmonics and the inverter drive.
