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()

DXF-assisted User Defined Hole-Magnet

The IPMSM User Defined editor accepts DXF reference points and curves. Selected geometry is normalized into the Points, Connections, and Magnetization model. The editor reuses shared endpoints and arc centers, provides an X-axis intersection helper, and supports Save Draft before formal validation.
