Hello,
I'm a student, working on project related to electric motor. Currently I'm trying to simulate a 350W power axial flux motor on Ansys Maxwell 3D. Until now I have been able to get BEMF of motor, further I'm trying to find losses in motor like core losses & copper losses. The core loss data is only available at 50 & 60 Hz for the material I chose for core but the motor will be operating at 500-600 Hz. So can anyone help me out how should I proceed to get core losses & copper losses of motor in Ansys Maxwell 3D software.

FAQ: Axial flux motor core loss model simulation

What is an axial flux motor, and how does it differ from a radial flux motor?

An axial flux motor is a type of electric motor where the magnetic flux travels axially through the motor, parallel to the axis of rotation. This contrasts with radial flux motors, where the magnetic flux travels radially, perpendicular to the axis of rotation. Axial flux motors are known for their compact design and high power density, making them suitable for applications where space is limited.

Why is it important to model core losses in axial flux motors?

Modeling core losses in axial flux motors is crucial because these losses can significantly impact the motor's efficiency and thermal performance. Core losses, which include hysteresis and eddy current losses, occur in the magnetic materials of the motor and can lead to increased heat generation. Accurate modeling helps in designing more efficient motors and in predicting their performance under various operating conditions.

What are the main components of core losses in axial flux motors?

The main components of core losses in axial flux motors are hysteresis losses and eddy current losses. Hysteresis losses occur due to the repeated magnetization and demagnetization of the core material, while eddy current losses are caused by circulating currents induced in the core material by the alternating magnetic field. Both types of losses depend on factors such as the material properties, frequency of operation, and the geometry of the motor.

What simulation tools are commonly used for modeling core losses in axial flux motors?

Common simulation tools for modeling core losses in axial flux motors include finite element analysis (FEA) software such as ANSYS Maxwell, COMSOL Multiphysics, and JMAG. These tools allow for detailed electromagnetic simulations that can accurately predict core losses by considering the motor's geometry, material properties, and operating conditions. Additionally, specialized software like Motor-CAD can be used for thermal and electromagnetic analysis.

How can the accuracy of core loss simulations in axial flux motors be improved?

The accuracy of core loss simulations in axial flux motors can be improved by using high-fidelity material models that account for the non-linear and frequency-dependent behavior of the core materials. Additionally, incorporating detailed geometrical features of the motor, such as laminations and air gaps, can enhance the simulation's precision. Calibration of the simulation model with experimental data is also essential to ensure that the predictions align with real-world performance.
