OVER the past few decades, various studies have been
made on induction motors. Some studies have been made
on the analyses of the interbar current [1]–[3], the analyses of the
induction motor driven by the inverter [4]–[6], and the thermal
analysis of the induction motor [7], [8]. In order to improve the
efficiency of induction motors, the matrix-rotor has been proposed
[9], however, there are few studies of the analysis of the
matrix-rotor induction motors. The rotor core of the matrix-rotor
is covered with the secondary conductor. It is desired for the
optimal design to analyze the various characteristics of the matrix-
rotor induction motor numerically, because it is not easy
to make the trial models of the matrix-rotor induction motor.
Therefore, we analyzed the static and the dynamic characteristics
of a matrix-rotor induction motor using the 3-D finite element
method on the parallel computing system developed by us.
Using the parallel computing system, the matrix-rotor induction
motor can be analyzed in a practical time.
