We analyzed the magnetic field and stress of an interior permanent magnet (IPM) motor with the off-centered rotor using the three-dimensional finite element method (3-D FEM), and clarified the effects of the off-center of rotor on the stress.
In order to improve the convergence for steady-state analysis, the simplified singularity decomposition-explicit error correction (SD-EEC) method is developed. This paper proposes techniques to apply the simplified SD-EEC method to an interior permanent magnet (IPM) motor and to an induction motor. The usefulness of the techniques is verified through the applications to an interior permanent magnet...
An interior permanent magnet (IPM) motor driven by a voltage source inverter is analyzed using the three-dimensional finite element method (3-D FEM) on the PC cluster composed of 16 PCs. The effects of the carrier harmonics on the current, the torque and the loss are numerically clarified. The validity of the calculation is clarified though the comparison between the measured results and the calculated...
The electrical loss of an interior permanent magnet (IPM) motor driven by the multilevel PWM inverter with several carrier frequencies is clarified using the three-dimensional finite-element method (3-D FEM).
We clarified the effects of permanent magnet division on the electrical loss and temperature distribution of an interior permanent magnet motor driven by the PWM inverter using the 3-D finite element method.
