摘要/Abstract

摘要： 对飞机电推进系统双通道永磁电机进行了研究，首先阐述了双通道电机系统在电推进飞机上的冗余输出原理，随后对比了不同绕组形式的双三相电机，提出了采用移相双三相绕组的双通道永磁电机形式，着重研究了移相双三相电机的电磁特性。然后分析了其不同工况下的定子损耗分布特性，并结合电机冷却方式和散热能力，计算了电机在发生局部故障以单通道运行时的输出能力。最后研制了110 kW双通道永磁电机原理样机，通过实验对分析结果进行了验证。计算结果表明电机在单通道运行时可维持至少70%额定功率的输出，可为飞机在应急情况下提供冗余动力。

Abstract: This paper studies the dual-channel permanent magnet synchronous machine of the aircraft electric propulsion system. Firstly, the redundant output principle of the dual-channel machine system on the electric propulsion aircraft is explained. Then, the different forms of dual three-phase winding structures are compared. A dual-channel permanent magnet synchronous machine with phase-shifted dual three-phase windings is proposed. The electromagnetic characteristics of the dual three-phase synchronous machine with phase-shifted windings are emphatically studied. Also, the stator loss distribution characteristics are analyzed. Combining the cooling capacity and the stator loss distribution characteristics, the single-channel output capacity of the proposed dual-channel permanent magnet synchronous machine when a partial failure occurs is calculated. Finally, a 110 kW dual-channel permanent magnet synchronous machine prototype is developed. The analysis results are verified through experiments. The calculation results show that the machine can maintain an output power of at least 70% rated power when operating with a single channel, which can provide redundant power for the aircraft in emergency.

Key words: electric propulsion aircraft, propulsion motor, dual-channel permanent magnet synchronous machine, phase-shifted dual three-phase winding, electromagnetic characteristic, loss distribution characteristic, redundant output capability
