摘　　要：高功率密度和高可靠性电动作动器是全电飞控系统发展的一个重要方面 ,其中电机及其控制系统是其中最重要的部件之一 ,是实现全电飞控系统的关键技术。同步磁阻永磁电机作为一种同步磁阻 (SynR)电机和同步永磁电机 (PMSM)相结合而产生的一种新型电机 ,是电动作动器用电机的重要候选者之一。本文首先介绍了该电机的基本结构和工作原理以及研究现状 ,然后给出了它的基本电磁方程和一般的分析方法 ,指出场分析是研究该类电机必不可少的方法 ,并指出机电一体化设计是其能否得到有效应用的关键。随后重点分析比较了它在电动作动器应用中的优势 ,指出同步磁阻电机的高可靠性、高效率、高功率密度、自然双余度。High power density and reliability electromechanical actuators (EMA) are the most important aspect of all electric airplanes. As the core component of EMA, the motors and its control system are the key factor to realize all electric airplanes. Synchronous Reluctance Permanent Magnet (SR-PM) motor, which is combination of Permanent Magnet Synchronous Motors (PMSM) and Synchronous Reluctance Motors (SynRM), is a good candidate of the motors used for EMA. The basic operating principle, structure and state-of-the-art of SR-PM motors are introduced firstly. Then its mathematic model and normal analysis methods have been presented and it is indicated that field analysis is the absolutely necessarily method for designing these motors. The integral electric and mechanical design is the key point for the successful spread of this motor. Whereafter advantages of the application of SR-PM motors in EMA have been discussed and compared with other type motors. The high reliability, efficiency, power density, unique double redundancies structure, super wide constant power range and so on give its good future in electromechanical actuators applications, so much as all the aero field.
