同期リラクタンスモータの動的数学モデルに関する一考察 : モデル特性の簡易統一的解析 A New Investigation of Dynamic Mathematical Model of Synchronous Reluctance Motor : A Simple Unified Analysis of Model Characteristics
This paper presents a new characteristics analysis of dynamic mathematical model for synchronous reluctance motor, which is recently attracting attentions in conjunction with the problem of rotor phase selection and estimation based on the extended BEMF (back electromotive force) for sensorless drive. This paper gives the following new characteristic results in a simple unified analytical manner. 1) Change between positive and negative salient pole phases requires basically no modification to the dynamic mathematical model in the general reference frame. 2) Selection of positive or negative salient pole phase as rotor phase is no more than a preference of designers. 3) There exists a very simple deriving method of two stator flux models for explicit expression of the extended BEMF. 4) At least, four circuit equations with the extended BEMF exist, which are equivalent to each other on the same reference frame. 5) There exists duality among the four circuit equations from viewpoints of rotor phase selection. 6) The duality reinforces the above-mentioned results 1) to 5). Main results of this paper correct or reinforce the results recently reported by others.
