5.3 Configuring the Electrical Models

Circuit Model File Path: <Public Documents>\National Instruments\<NI VeriStand 20XX>\Examples\OPAL-RT\Power Electronics Add-On\6-Phase PMSM Local Control\Circuit Model\PMSM_eHS_UB.mdl

Configuring the 6 Phase PMSM Model

In this example, the PMSM model and associated sensors have been pre-configured. For more information related to machine configuration, please refer to the 6-Phase PMSM BLDC Section. Explore the configuration of the machine by following the steps below.

  • In the Configuration Tree, expand Circuit Model >> Machines and click 6-Ph PMSM BLDC 1 to open the configuration page for the machine.

  • Observe the configured machine parameters. The Input Mapping subsection allows the outputs of the circuit model to be connected to the inputs of the machine.

  • In the Configuration tree, expand 6-Ph PMSM BLDC 1 and click Mechanical Model to view the mechanical model parameters.

  • Confirm that the parameter values match those in the table below.
