Detailed information
-
Maximum magnetic flux density Maximum magnetic flux density distribution of 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, high 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 formed 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 made up 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, which leads to a large iron loss, but the reason for the significant iron loss at the T-shaped coupling section 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, the rotating magnetic flux is significantly present. Additionally, the transformer leg is a location where alternating magnetic flux occurs along the direction of magnetic charge ease, but a small rotating magnetic field can be observed. This is a result not achievable by conventional methods.
