MATLAB: The documentation for the demo c2812pmsmsim is incorrect in Embedded Target for TI C2000 DSP 2.1PR (R2006b_prerelease)

Question

I see an inconsistency between the demo model and its description in the INFO block. In the motor model, the number of pole pairs is one; in the description, the number of poles is four (two pole pairs). When the number of pole pairs is greater than one, the rotor electrical position is different from the rotor mechanical position. This difference needs to be considered inside the controller block. The demo model should demonstrate operation more than one pole pair.

Answer 1

This is an error in the documentation for the demo c2812pmsmsim in Embedded Target for TI C2000 DSP 2.1PR (R2006b_Prerelease).

There is an error in the description of the demo's parameters. The INFO block in the demo lists the number of poles in the PMSM block as four (two pole pairs). However, the PMSM block in the demo has only one pole pair.
