[JAC286] IPM Motor Iron Loss Analysis Accounting for PWM -Evaluation with Different Modulation Methods-
PWM control is widely used in the control of IPM motors. Because currents include carrier harmonics, this results in an increase in iron loss. Many different types of control methods are available. Modulation methods are selected according to the objective and application of the control. The carrier harmonic components of a current will vary depending on the modulation method. Assessing iron loss is essential in improving the efficiency of IPM motors, and the modulation method must also be accounted for in order to evaluate the iron loss accurately.
By using a magnetic field analysis simulation that accounts for control, the iron loss accounting for the PWM control carrier harmonics can be assessed.
In this example, the effects on iron loss when the modulation method for PWM control is changed are evaluated.

Please see the website for “Current Waveforms” and “Iron Loss”.

JMAG Open Interface programs

We have updated our site introducing case studies of linked analysis.
In recent years, the sophistication of electrical equipment design is required. As known there is a limit to the design of magnetic circuits alone, therefore multifaceted evaluations such as structure, vibration, heat, and control are required at the same time.It is more efficient to perform coupled analysis by linking different software where they have their own strength in the respective physical phenomenon rather than to adhere to one CAE software.
