1. Establish the motor model in ANSOFT software

Step 1: Draw the motor model in ANSOFT

Step 2: Select the “Export” item under the “Modeler” menu and the following window will appear.

Select to save as a “step” format file. You can now exit the ANSOFT software.

ANSYS Simulation

1. Steady-state temperature simulation

The first step is to create a steady-state temperature simulation model

The second step is to add materials and properties. The properties are mainly “Thermal conductivity

Select Engineering data”Edit”

Step 3. After adding the material, import the motor model created in ANSOFT, select “Geometry” and select the following options

ANSOFT Modeling

Select the motor model in the “step” format saved in ANSOFT

Step 4. After importing the model, add materials to the model. Select “Model”→”Edit

ANSOFT Modeling

Enter the window below and follow the steps below to select the corresponding materials for each part of the motor.

 

 

Step 5. After adding materials, return to the main window and update the modified project file

If there is no problem,will become

Step 6: Add heat load

First add degrees of freedom, select temperature in temperature field analysis, and select according to the window below.

Next, edit the temperature and select the region to apply to, here defining the same initial temperature for the entire model.

Next, add a heat load and select according to the window below. Here, select “Heat Generation Rate”.

Edit the added heat generation rate value and select the application area, here all windings.

After adding the load, update the project file. Once passed, you can select “Solve” to solve.

If the solution is successful, the left window will become the right window.

 

Step 7: Check the simulation results. Select the observation variable in the window below.

2. Transient Temperature Simulation

Step 1: Establish a transient temperature analysis model

The second step is to add materials and properties. The method is the same as in steady state. However, the properties of the materials are different. Here, you need to add the material’sDensity”, “thermal conductivity”, “specific heat capacity”.The “Toolbar” window is as follows.

Follow the options to add data.

The next steps are the same as for steady state, except that the load is added differently.

Set the number of simulation steps to multiple steps.
