关于永磁同步电机交、直轴电感的计算,forlink队长已经写过一篇用静态场计算的帖子。内容非常详尽,解释也非常到位,在此向队长致敬。
本文题目:Determination of d-q Axis Parameters of Interior Permanent Magnet Machine

摘要:
In this paper, a new approach is presented for extracting saturated parameters Ld , Lq and permanent-magnet flux linkage λmd with arbitrary load conditions for interior permanent-magnet (IPM) synchronous machines. The procedure starts with the parameter extraction in actual abc reference frame based on transient finite element analysis (FEA) in time domain. Then, the parameters in abc reference frame are transformed to d-q axis reference frame via Park transformation. This approach is able to provide better accuracy and allow easy implementation because the parameters are derived from a realistic physical representation and the effects of the slot leakage and phase-spread harmonic fields are included in the simulation. |
