Model Description Method of AC Motors Using 3×3 Balanced Circular Matrices

Abstract

This paper presents a new model description method for AC motors such as salient-pole synchronous motor, synchronous reluctance motor and induction motor. The method uses specific 3×3 balanced circular matrices together with 3×l balanced vector signals. It does not require concept of rotational orthogonal coordinates but has the same vector description form as the orthogonal coordinates. The method is useful for easy comprehension of motor dynamics especially by students and engineering-beginners.
