The measured angular velocity is mechanical angular velocity, and needs to be transformed into electrical angular velocity for later blocks. The reason the mechanical velocity is being multiplied by the number of pole pairs is due to the electrical angular velocity being equal to the mechanical angular velocity multiplied by the number of pole pairs in the Permanent Magnet Synchronous Machine. Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation:
