“…A short-circuit fault is one of the most dangerous faults for PMSMs. Even if the power supply to the winding is cut off, the rotor and the main magnetic field will keep rotating due to inertia, thus generating counter-electromotive force in the stator winding; on the other hand, the resistance of the short-circuit winding decreases sharply, and there will be a large short-circuit current in the short-circuit winding, generating a large amount of copper loss in a short time, which may burn up the winding in serious cases [88]. As can be seen from Equation (7), the self-inductance of the motor will play an important role in limiting the magnitude of the short-circuit current by increasing the value of motor self-inductance, which will be controlled within the range that the motor can withstand to prevent the short-circuit fault from bringing further damage to the motor.…”

As the electrification process of aircrafts continues to advance, the propulsion motor system, as its core component, has received more attention and research. This paper summarizes and analyzes the development status, research focus and typical cases in this field in recent years. Firstly, it analyzes the basic structure and principle of five common motors, summarizes the current status of their respective applications in electric aircrafts, and compares them to determine the most suitable type of motor for use as a propulsion motor, focusing on various performance indexes. Then, the optimized design of propulsion motors is generally divided into two categories, namely high power density and fault tolerance. Starting from the basic relationship equation of motor design, the basic method to improve the power density of motors is pointed out; at the same time, according to the basic principles and objectives of the fault tolerance of motors, the fault tolerance design is divided into two aspects, namely the redundant design and the design to improve the fault tolerance capability. Finally, this paper summarizes the current development status of the propulsion motor system and the existing problems and points out the main development direction of this field in the future, so as to provide reference for the further development of the electric propulsion system of aircraft.

“…Numerous control techniques have been proposed to present high performance control of servo systems, and the parameters of magneto-synchronous motors can be affected by temperature, stator winding current and flux saturation during operation [3][4][5]. In addition, changes in electrical parameters are considered as an indication of servo system state changes; a short circuit between turns can lead to sudden changes in d/q-axis inductance and stator winding resistance [6], and demagnetization of the rotor permanent magnet can lead to a sudden decrease in the amplitude of the flux linkage [7]. Therefore, whether controlling speed, position, or torque control, the realization of high dynamic response and high precision control requires the use of accurate motor parameters, and obtaining accurate motor parameter values helps to improve the control performance of the whole servo system.…”

The parameters of permanent magnet synchronous motor (PMSM) affect the performance of vector control servo system. Because of the complexity of nonlinear model of PMSM, it is very difficult to identify the parameters of PMSM. Aiming at the problems of large amount of data calculation, low identification accuracy and poor robustness in the process of multi parameter identification of permanent magnet synchronous motor, this paper proposes a weighted differential evolutionary particle swarm optimization algorithm based on double update strategy. By introducing adaptive judgment factor to control the proportion of weighted difference evolution (WDE) algorithm and particle swarm optimization (PSO) algorithm in each iteration process, and consider using PSO algorithm or WDE algorithm to update individuals according to the probability law. The individuals obtained from WDE operation are used to guide the individual evolution process in PSO operation through the information exchange mechanism. The proposed WDEPSO algorithm can ensure the diversity and effectiveness of the individual evolution of the population. The algorithm is applied to parameter identification of PMSM drive system. The simulation results show that the proposed algorithm has better convergence performance and has strong robustness, parameter identification of permanent magnet synchronous motor based on proposed method does not need to rely on more data sheet on the motor design value, can motor stator resistance identification at the same time, the rotor flux linkage, d/q-axis inductance and electrical parameters, and can effectively track the parameters value.
