Special Issue Information

Dear Colleagues,

Zero-carbon emission is currently pushing the rapid development of electric propulsion, including electric vehicles and electric aircraft. Electric machines, regarded as one of the core components in electric propulsion, are being intensively studied to meet the increasing demand for performance in the drive system. Various types of electric machines, such as permanent magnet synchronous machines, induction machines, and reluctance machines, are promising candidates for electric propulsion. However, different types of electric machines are facing their own challenges, requiring innovative solutions. In this Special Issue, we welcome submissions to improve the performance of electric propulsion systems, focusing on advanced speed/current/torque control methods, fault-tolerant control methods, sensorless control methods, control technologies for new inverter topologies, novel motor topologies, emerging motor design methods, etc.

Abstract

The permanent magnet vernier synchronous machine (PMVSM) has the characteristics of high torque density and high power density and has advantages in the field of low-speed and high-torque applications. The PMVSM utilizes rich harmonics for torque enhancement, but it can also cause an increase in radial electromagnetic force and vibration noise. In this paper, we take a 12-slot 10-pole PMVSM as an example to analyze the source of radial electromagnetic force, vibration and noise. The electromagnetic finite-element model and structural finite-element model of the PMVSM are established for calculation. Through the analysis and calculation of two-dimensional electromagnetic fields, the radial electromagnetic force distribution of the PMVSM is obtained. We derive the radial electromagnetic force formula of the PMVSM and verify the correctness of the formula through harmonic analysis of the radial electromagnetic force. The sources of radial electromagnetic forces at various orders and frequencies within the PMVSM are analyzed and summarized by coupling the radial electromagnetic force obtained from the electromagnetic finite-element model to the structural finite-element model and conducting electromagnetic vibration harmonic response analysis on the PMVSM. The measured acceleration spectrum of the prototype is compared with the finite-element method (FEM) results, verifying the correctness of the finite-element simulation results for electromagnetic vibration.
