Using the Asynchronous machine SI Units in Delta connection is possible ?

Hello, I am trying to simulate the operation of a three-phase induction machine using Matlab Simulink, but I need the stator connection to be in delta configuration. The motor available in Matlab Simulink is pre-configured in wye (star), and I am unable to change it. I tried using the Phase Permute, but it doesn't connect with the objects in the current versions of Matlab. Does anyone have any idea how I can change the stator connection from Y to Delta?

Hi Gabriel,

To change the stator connection from Y (wye) to Delta configuration in Matlab Simulink, you can employ a workaround using Simulink blocks and custom connections. Open your Simulink model that contains the three-phase induction machine. Add three Phase Splitter blocks to split the phases of the wye-connected stator. Then, connect the outputs of the Phase Splitter blocks to a custom Delta Connection block. Inside the custom Delta Connection block, implement the logic to connect the three phases in a delta configuration by using Signal Routing blocks like Mux and Demux to create the delta connection pattern. Then, connect the output of the custom Delta Connection block to the stator of the three-phase induction machine. Ensure that the connections are correctly mapped to simulate the delta configuration effectively. Hope this will help you accomplish your objective.

This is possible using the Simscape Electrical blocks, blue ones. Both ends of the windings are exposed and can be connected in either wye or delta outside the block. Check out this example:
