Configuring the 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 PMSM BLDC Section. Explore the configuration of the machine by following the steps below.
- In the Configuration Tree, expand Circuit Model >> Machines and click 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 easily connected to the inputs of the machine.
- In the Configuration tree, expand PMSM BLDC 1 and click Mechanical Model to view the mechanical model parameters.
- Confirm that the parameter values match those in the table below.
