Introduction: Electromechanical Perspective 简介：电磁产品研发愿景

ANSYS has a comprehensive portfolio of simulation packages. Our goal is to provide tools that enable Electric Engineers to solve their problems in the most efficient way

ANSYS focus:

- Developing cutting-edge technology solving real world problems faster

- Enabling couplings between 3D physics solvers where it is relevant

- Leveraging the high-fidelity of 3D simulations into the “0D” system simulation design

• Some electromechanical devices rely on Vector Hysteresis to function Hysteresis motors

• Some Electromechanical devices have some remanent behavior that

only a Vector Hysteresis formulation can capture Sensors/Actuators

• Loss accuracy - Captures both alternating and rotational fields. The

global trend of designing more energy efficient power devices pushes us to provide better loss accuracy. The traditional method (Steinmetz) has limitations are removed by the new Vector Hysteresis Modeling.

In R15 and Before: → User input data points will be used to construct analytic function derived from curve fitting based on minimum least- square approach → It is desirable if the sampling points are close-to evenly distributed along H-axis, not B-axis

In R16: → Maxwell uses the actual points that are entered by user → More accurate representation of BH characteristic if measurements are used

More accurate B-H handling 更精确的B-H曲线处理方法

• Best Practices to Better and Faster Convergence – BH data should be smooth (including derivatives) and enough datapoints

• To provide low-field data as well as high-field data
