IPMSM HoleMagnet

The hole_magnet attribute of the Project.rotor corresponds to the Rotor Hole Magnet CheckPoint in the GUI. It is an instance of the IPMSM_HoleMagnetData class, which can be accessed through eMotorSolution.CheckPoints.Rotor.IPMSM_HoleMagnet.

It holds the properties of all rotor hole-magnet pairs in the collection list. Adding or removing hole-magnet pairs is simply done by appending or removing items from this list.

Parameters

• _collection: list A list of hole-magnet pairs.

Hole-Magnet Pair

• Type 51
• Type 51M
• Type 52
• Type 52C
• Type 52D
• Type 52R
• Type 53
• Type 54
• Type 55
• Type 57
• Type 58

Example Usage

Assuming that the project is an IPMSM one:

import eMotorSolution as ems

from eMotorSolution.CheckPoints.Rotor.IPMSM.IPM_HoleMagnet52R import IPM_HoleMagnet52RData

# Load the project
project = ems.load_project("path/to/your/project.json")

# Print the list of current Hole-Magnets
print(project.rotor.hole_magnet.collection)

# Create a new Hole-Magnet
new_hole_magnet = IPM_HoleMagnet52RData(
    W0_expression=30,
    W0_unit="mm",
    W3_expression=6,
    W3_unit="mm",
    H0_expression=3,
    H0_unit="mm",
    H1_expression=9,
    H1_unit="mm",
    H2_expression=1,
    H2_unit="mm",
    R0_expression=1.8,
    R0_unit="mm",
    R1_expression=0.9,
    R1_unit="mm",
)
# Make sure to set the project data to get hints and proper validation
new_hole_magnet.project_data = project


# Add the new hole magnet to the project
project.rotor.hole_magnet.collection.append(new_hole_magnet)

hints = new_hole_magnet.hints  # Get hint Values
print(hints)

project.show()
