To decrease the cost of low-frequency linear motor such as M-EMS (in-mold electromagnetic stirring) system and to obtain the process characteristics, it is necessary to estimate the maximum current and voltage as well as the distribution of magnetic flux density precisely. According to the measurement result of the M-EMS unbalanced three-phased electrical circuit, we find out that the standard deviation of the voltages is much smaller than that of currents. Then, it makes clear that the voltage source electromagnetic calculation is useful for the M-EMS design to obtain the maximum current and the magnetic flux density, through the comparison data of the experiment and the calculation.
