RTE-Drive Machine

Block

Note: This block is obsolete.

Description

This block implements a 3-phase permanent magnet synchronous machine with sinusoidal flux distribution. The machine is modeled in the park D-Q rotor reference frame. Stator windings are connected in wye to an internal neutral point.

Note: that the mathematical model is valid for fixed Lq and Ld parameters. The RTE-Drive Full Park D-Q PMSM provided a mathematical model that solves this problem.
