LinearPermeability

The LinearPermeability class represents the linear permeability of a non-magnet materials. This class is accessed through the eMotorSolution.CheckPoints.Materials module.

Parameters

• relative_permeability_expression: str | float - The relative permeability of the material, which can be a string mathematical expression or a float value.

Methods

Method	Description
set_relative_permeability(expression)	Sets the expression: str | float for the relative permeability of the material.

Attributes

Attribute	Description
relative_permeability	float Returns the evaluated relative permeability of the material. ⚠️ read-only

Example Usage

This example demonstrates how to create a LinearPermeability instance for a non-magnet material.

import eMotorSolution as ems
from eMotorSolution.CheckPoints.Materials import LinearPermeability, Non_Magnet_Material

# load an existing project
project = ems.load_project("path/to/your/project.json")

# Create a LinearPermeability instance
linear_permeability = LinearPermeability(relative_permeability_expression="1.05")

# Add a new non-magnet material
new_material = Non_Magnet_Material(
    name="NewMaterial",
    conductivity_expression= 1e7,
    conductivity_unit="S/m",
    permeability=linear_permeability
)

# Add the new material to the project's materials collection
project.materials.collection["NewMaterial"] = new_material
