OZEN Engineering - Motor-CAD Mechanical Coupling
Hello everyone, this is Meysam Meir Averon. I'm going to present this demo for you about Motor-CAD and mechanical coupling. If you're a part of OZEN Engineering, Inc., you're a part of the ANSYS family. Let me explain what we do:
- We sell ANSYS products.
- We provide customer support for these products.
- We conduct training sessions if necessary.
- We offer consulting services in various fields such as structural, fluids, optics, systems, and semiconductors.
In your business, whenever you need any simulation tools, feel free to contact us. We probably have a tool that can help you.
Using Motor-CAD
I'm going to show you how to use CAD from Motor-CAD after designing an electric model and then bring it into mechanical for FE analysis or any other program. As you know, Motor-CAD is a parametric tool. Here's a sample:
- You have a radial picture and slot numbers.
- All these parameters are input manually without having a CAD.
- You input the length, shaft diameter, and other factors.
Based on these inputs, Motor-CAD provides a three-dimensional simple CAD. As you see here, this is the motor we have; it includes the rotor, stator, and shaft. We need to export this CAD to mechanical to perform FE analysis.
Exporting CAD
- Go to Files and then Geometry Export.
- Choose from different formats like DSC, DXF, ANSYS Electric Desktop, or Design. We use the more generic format, STL.
- Save it to a target folder for CAD mechanical.
Once exported, you'll find all the components saved in the folder. We can bring these into SpaceClaim and ANSYS Mechanical. In SpaceClaim, you can see all the geometries and components of the motor.
Performing FE Analysis
We focus on the rotor and shaft, not the stator, to analyze stress due to centrifugal force. In ANSYS Workbench:
- We have the material data and geometry to feed the static structure model.
- In ANSYS Mechanical, you can assign materials, mesh the model, and impose a rotational velocity.
- For example, assume a rotational velocity of 150 radians per second.
- Apply frictionless support on the shafts.
Based on these settings, you can perform FE analysis to determine deformation and stress distribution. The analysis shows radial deformation and identifies areas of maximum and minimum stress.
Additional Tools
You can perform similar analyses using other tools such as:
- Modal analysis
- Fluent
- NVH tools
- ANSYS Electronic Desktop
Thank you for your attention, and have a great day. Goodbye.

We probably have a tool that can help you with that. I'm trying to show you how to use a CAD from Motor-CAD after designing an electric model and then bring it into mechanical for FE analysis or any other program. As you know, Motor-CAD is a parametric tool.
When you're dealing with it, you have a radial picture and slot numbers, which are parameters that you put manually without having a CAD. Then, you have the actual parameters, such as the lens, shaft diameter, and all those factors. Based on that, it would give you a three-dimensional simple CAD.
Here is the motor we had. It has a rotor, stator, and shaft. If you'll notice, these are all the parts we are going to have. We need to export this CAD to mechanical to be able to do some FE analysis on that. To do that, we go to Files, then Geometry Export.
We can have different formats like DSC, DXF, or ANSYS Electric Desktop or Design, or even a Star System, but we use the more generic one, which is the STL. We go to this folder, find a target desktop or the CAD mechanical like a new folder, and save it here. Then export.
If you go to that folder, you'll see that it had saved all the components inside of it, such as the rotor and the shaft. So, as you see, we can bring all these into Space Claim and even into the ANSYS Mechanical.
Here, we see the Space Claim, and then if we bring it in, we would have all these geometries. If we open it, you see we have the components of the motor.
But as I mentioned, because we are trying to see how much is the stress because of the centrifugal force, we would need to just do rotors and the shaft, not the stator. So, we can bring these parts into Mechanical.
If you go to ANSYS Workbench, as you see, we have the material data and so we have the geometry, which is going to feed the static structure model. Based on that, we will be able to build a mechanical model. Here, you have all these three parts.
You can assign materials into them, then mesh it, and then impose a rotational velocity on it. Let's say here we assume it's going to be 150 radians per second, which is a good guess. And also, we have the frictionless support on the shafts.
Based on that, we can do FE analysis and see the radial deformation and the maximum and minimum stresses. We can do the same thing with other tools, such as Modal, Fluent, or any other NVH tools, or even on the Electronic Desktop. Thanks for your attention, and have a great day. Goodbye.
