Troubleshooting Motor Simulation Results in Maxwell: Any Suggestions?

In summary: Search the Maxwell help file for "Export" options. There should be a way to export the code as text or CSV or similar, I would think.

Hello,
I'm trying to simulate a 3 phase hysteresis motor with 4 poles, 36 slots, 220 input voltage peak for each phase, 50Hz, specified dimensions and 0.6 N.m output torque in maxwell transient.
The magnetic material used is LNG52 which is also known as alnico600, alnico5DG(ACA52) and alcomax 3SC.
The rest of specs like efficiency or number of turns aren't presented, however the results are:
https://www.researchgate.net/deref/https%3A%2F%2Ffiles.fm%2Fu%2F7uav5xr7
This is the simulation file.
https://www.researchgate.net/deref/https%3A%2F%2Ffiles.fm%2Fu%2F6mhy4dyy
The problem is that my results no matter what the number of turns or efficiency are, are nothing like what they supposed to, for example the starting torque is so much lower and motor reaches the synchronous speed much much faster about 10 to 5 times faster than it should.
If you have any thoughts what the reason might be, it would be much appreciated.
kind regard,
Omid Feyz Najafian

I can't view the links. There seems to be a paywall. Please use the UPLOAD button to post the content you want us to see, or paste it in the post as text between CODE tags.

Dear anorlunda,

I'm sorry for the inconvenience.
These are how the results should be like:

I am not going to load and execute a program from a link. Can you post the source code as text?

Dear anorlunda,

Please explain how I can access the source code from a .mxwl file to send it in text format?

best regards,

I am not Maxwell knowledgeable. I'm just trying to help other PF members who might be able to give you an answer. They need to see something posted they can comment on; not an executable file that might contain malware. By source code I mean the data and instructions that you typed into Maxwell to set up your simulation.

Thank you for the tips.

1. What is motor simulation in Maxwell?

Motor simulation in Maxwell is a process of using computer software to simulate the behavior and performance of electric motors. This includes modeling the electromagnetic fields, mechanical movements, and thermal effects of the motor.

2. What are the benefits of using motor simulation in Maxwell?

Motor simulation in Maxwell can help optimize the design of electric motors, reduce development time and costs, and improve the overall performance and efficiency of the motor. It can also provide valuable insights into the motor's behavior and potential issues before physical prototypes are built.

3. Can motor simulation in Maxwell accurately predict real-world performance?

Yes, motor simulation in Maxwell uses advanced mathematical algorithms and physics-based models to accurately predict the performance of electric motors. However, the accuracy of the simulation also depends on the quality of the input data and assumptions made during the modeling process.

4. What types of motors can be simulated in Maxwell?

Maxwell has the capability to simulate various types of electric motors, including AC induction motors, permanent magnet synchronous motors, and brushless DC motors. It can also model different motor topologies and configurations, such as single-phase and multi-phase motors.

5. How does motor simulation in Maxwell compare to physical testing?

Motor simulation in Maxwell can provide valuable insights and predictions about the motor's performance, but it should not replace physical testing entirely. A combination of simulation and testing is often used to optimize motor design and ensure its performance meets the desired specifications.
