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.
