Suitable for motor vector magnetic characteristic analysis: Iron loss analysis tool / μ-E&S
μ－E&S
Aiming for low loss, accurately measure the actual state of electromagnetic materials and grasp and analyze their vector magnetic characteristics!
Iron loss evaluation, which has been a bottleneck in motor analysis. Conventional methods only consider iron loss as a function of magnetic flux density, resulting in low accuracy. However, accurately determining the magnetic field and magnetic flux density to calculate iron loss is achieved through "vector magnetic characteristic analysis." This allows for the calculation of high-precision distributions of magnetic fields, magnetic flux densities, and iron losses that are not achievable with other software. Vector magnetic characteristics refer to the properties that take into account the relationship between the magnetic field H and magnetic flux density B of electromagnetic steel materials, considering their direction (vector). The finite element method electromagnetic field simulator that incorporates this characteristic is “μ-E&S.” 【Features】 - High-precision calculation of magnetic field vectors is possible by considering vector magnetic characteristics. - Rotating magnetic fields and hysteresis can be calculated. - It is designed as an easy-to-use tool specifically for iron loss evaluation. *For more details, please request materials or view the PDF data available for download.

Detailed information
-
Maximum magnetic flux density Distribution of maximum magnetic flux density in IPM motors: The lack of variation in the circumferential direction is the same result as in conventional methods.
-
Maximum magnetic field strength Distribution of maximum magnetic field strength in IPM motors: The rolling direction is along the X-axis, and anisotropy is calculated even for non-oriented electrical steel sheets, resulting in high regions appearing in the upper and lower areas. This is a result that cannot be calculated using conventional methods.
-
Iron loss distribution Iron loss distribution of the IPM motor: Using the calculated results of H and B, hysteresis curves are drawn for each element, and the total area is used to calculate the iron loss distribution. Since the magnetic field strength was high in the upper and lower regions, higher portions of iron loss were also calculated in these areas. This is a result that cannot be obtained by conventional methods.
-
Hysteresis curve The magnetic flux density vector and magnetic field strength vector for each element have been obtained as calculation results, so the hysteresis curve is simply obtained by connecting them over one electrical angle cycle. There is no need to use algorithms such as hysteresis models.
-
Rotating magnetic flux / rotating magnetic field Lissajous waveform: The Lissajous waveform is the trajectory of the magnetic flux density vector and the magnetic field strength vector. The difference in the direction of each vector (spatial phase difference) is also obtained as a calculation result.
-
Maximum magnetic flux density Transformers are composed of oriented electrical steel sheets.
-
Maximum magnetic field strength In the T-shaped joint, the magnetization easy direction is shifted by 90 degrees, resulting in a region with high magnetic field strength.
-
Iron loss distribution The magnetic flux density is high inside the transformer window, so the iron loss is also large, but the reason for the large iron loss at the T-shaped joint is due to the high magnetic field strength. This is a result that cannot be obtained by conventional methods.
-
Rotating magnetic flux and rotating magnetic field In the T-shaped joint, a large rotating magnetic flux is present. Additionally, the transformer leg generates alternating magnetic flux along the direction of magnetic charge ease, but a small rotating magnetic field can be observed. This is a result that cannot be obtained by conventional methods.
