Ansys Motor-CAD: General Overview of the Motor Types and Physics Modules
Hello everyone, David Giglio here with Ozen Engineering. In this video, I will show you how to use Ansys MotorCAD to model, simulate, analyze, and post-process results to evaluate motor performance. This will help you choose the optimized motor design to achieve cost-effectiveness and efficiency.
MotorCAD Physics Modules
MotorCAD has four physics modules:
- Electromagnetics: Contains eight motor designs to choose from.
- Thermal: Offers nine motors for thermal module physics.
- Design of Experiments (Lab Module): Provides five motors for experiments and allows development of torque-speed curves and efficiency maps.
- Mechanical: Contains eight motors to choose from.
All motors highlighted in purple are available in the design of experiments for the lab.
Electromagnetics Module
In the Electromagnetics module, all tabs are highlighted in blue. Here, you can:
- View geometry in radial, axial, and 3D views.
- Input stator and rotor parameters.
- Examine winding patterns, including radial and linear patterns.
- Export designs for manufacturing.
- Analyze phasor diagrams, EMF plot harmonics, and winding definitions.
- Configure wire selection settings and output parameters for winding.
Each physics module requires material definitions and relevant physics parameters. For the Electromagnetics module, this includes electric resistivity and temperature coefficients.
Simulation Settings
Set up drive winding connections and magnetization temperatures. Choose between coupled and non-coupled simulations. Coupled simulations may take longer but typically complete within a few minutes.
Results
View results such as flux density, vector potential, and current density in tabular form. Configure settings for iron losses, laminated core loss calculations, and bearing losses. Choose between hybrid FEA or full FEA for practical and realistic results.
Thermal Module
This module includes the motor jacket for thermal cooling. You can:
- View the actual and 3D views of the motor with the jacket.
- Configure input data settings for thermal physics.
- Analyze temperature distribution using thermal circuit components.
Mechanical Module
Calculate rotor stress and view results for stress, strain, and displacement. Set torque-speed curves and export results to ANSYS Mechanical for full 3D analysis.
Lab Module
Obtain calculations for torque-speed curves and efficiency maps. Analyze different drive cycles and determine the most efficient motor design within specific RPM ranges.

Hello everyone, David Giglio here with Ozen Engineering. In this video, I will show you how to use ANSYS MotorCAD to model, simulate, analyze, and post-process results to evaluate motor performance, helping you choose the optimized motor design for cost-effectiveness and efficiency.
MotorCAD has four physics modules: 1. Electromagnetics, containing eight motor designs to choose from 2. Thermal modules, with nine motors to choose from 3. The lab module, allowing you to develop torque and efficiency maps, and offering five motors to choose from 4. Mechanical physics, containing eight motors to choose from All the motors you see here, highlighted in purple, are available in the design of experiments for the lab.
Let's start with the Electromagnetics module. Here, you will find all the tabs highlighted in blue. The Geometry tab shows a radial view of the geometry, with panels on the left side for inputting stator and rotor parameters. Changing any of these parameters will update the geometry in the model.
You can look at the radial, axial, 3D, and winding views, as well as the slot and linear patterns. The winding view shows the radio pattern, number of throws, winding layers, and coil view. The slot view allows motor designers to export the design for use in a machine for manufacturing the motor.
In the Electromagnetics module, you can look at single phases, phasor diagrams, MF plot harmonics, and associated factors. You can choose hairpin, stranded coils, overlapping, or other options for the winding definition.
For the wedge model, you can choose wedge, round, or space, and configure the wire selection settings for dimensions. The output parameters for the winding setup are similar to those for other physics models, including thermal and mechanical.
For each physics, you need to set up material definitions and relevant physics parameters. For the electromagnetic module, you will see electric resistivity, temperature coefficient for electrical resistivity, and other relevant information.
For the calculation, you need to set up the drive on the winding connections, magnetization temperatures, and a fixed temperature for the starting point in a multi-physics coupling simulation or a fixed temperature for a non-coupled simulation.
You can choose non-coupling, magnetic losses to thermal, or other coupling options. The simulation time depends on the number of results for the output and whether you're doing a coupled or non-coupled simulation.
It typically takes a few minutes, but can take up to 15 minutes for complex simulations. Now, let's look at the thermal model. This module includes the jacket of the motor for thermal cooling. You can see water forced inside the jacket and flowing around to allow thermal cooling.
The 3D view with the jacket and full enclosure included shows the temperature distribution. For input data, you have similar settings as for the electromagnetic module, as well as additional relevant settings for thermophysics. The mechanical model calculates rotor stress.
You can see different results, such as the magnitude of the result or individual components in the radial or tangential direction. You can also set the torque speed curve and calculate the required speed.
MotorCAD will calculate the torque as close as possible to the requested torque and give the corresponding currents, line, and phase. These results can be exported to ANSYS Mechanical for full 3D mechanical analysis. In the lab module, you can obtain the calculation for the torque speed curve.
The shaft torque versus speed curve is the torque speed curve profile envelope from which the efficiency map will be used to develop. The efficiency map helps motor designers choose designs and guide them in making decisions regarding motor design parameters.
The highest efficiency for the motor occurs in the range between 2000 and 10,000 rpm. Thank you for watching. Please like this video if you find it helpful, subscribe to our channel, and visit our website at [www.ozening.com](http://www.ozening.com).
