Extension of the Park’s Transformation Applied to Non – Sinusoidal Saturated Synchronous Motors

Abstract

This paper presents an extension of the Park transformation that takes into account the magnetic circuit saturation. This transformation applies to variable reluctance synchronous motors, excited or not. This method follows from the evolution of the operating point with constant torque and minimum copper losses in the Concordia frame.

Key Words:

• synchronous motor
• saturated modeling
• torque undulation reduction.
