Permanent Magnetic Synchronous Motor — permanent magnet synchronous motor model using a JMAG-RT model

The Permanent Magnet Synchronous Motor JMAG-RT component uses external code, provided through an attached .rtt file, to model a permanent-magnet, three-phase, synchronous electric motor.

Use the following steps to attach and connect to an external rtt file:

1. 

Select the Attached Files tab.

2. 

Right-click on Documents, and then select Attach File....

3. 

In the Attach Document dialog, browse to the location of the .rtt motor file, select it, and then click Attach....

4. 

Select the JMAG-RT component in the Model Workspace.

5. 

Select the Properties tab, open the Parameters > General section, and then select the attached .rtt file from the rtt_filename list.

This component should be used with a fixed-step solver. To select a fixed-step solver, click the Settings tab, expand the Simulation section, and then select Fixed from the Solver Type list.
