Iron consumption of the motor calculate
TECHNICAL ARTICLES
Overall, there are two ways to calculate the iron consumption of a motor,
One method is to directly calculate the iron consumption using a physical model of silicon steel sheets. The direct calculation of iron consumption usually uses finite element analysis (FEA), which calculates the iron consumption of silicon steel sheets directly based on electromagnetic field equations and material properties. This method is computationally complex and requires high requirements for simulation calculations and settings. It is commonly used to calculate the iron losses of motor magnets and conductive sheaths.
Another method is to use silicon steel sheet test iron consumption data to calculate iron consumption. Using a loss model to calculate the iron loss of the motor, the iron loss of the motor core is calculated by first selecting a calculation model for iron loss, such as Steinmetz Model or Bertotti Model, and then fitting the required coefficients in the model based on the iron loss test data of the silicon steel sheet. Finally, the finite element method is used to calculate the iron loss of the motor core based on the alternating magnetic induction intensity B and frequency F of the motor model.
