Special Issue Information

Dear Colleagues,

Permanent magnet synchronous motors proved their superiority to other electrical machine types in terms of efficiency, power density, reliability, and flexibility, and gained significant interest of researchers and industry professionals over the last few decades. Various domains such as automotives, air space, power generation, military, medical, automation, and robotics currently use various types of electrical machines in different configurations.

However, the limited nature of resources needed to obtain high-performance permanent magnets and relatively high fabrication costs represents inconveniences that can be overcome by developments in achieving even better performance through an optimal design of both motor geometry and control strategy. Thermal and mechanical aspects represent serious challenges in permanent magnet electrical machines and should not be neglected. As an alternative to these shortcomings, interest in cheaper permanent magnets, such as ferrite used in electrical machines with convenient topologies, is currently increasing.

This Special Issue calls for papers that explore innovative applications of different permanent magnet electrical machines in terms of design and modeling approaches, drive topologies, motor control stratgies, fault tolerance, and redundancy.

I look forward to receiving your contributions.

High-speed direct-drive permanent magnet synchronous motors (PMSMs), supported by elastic foil gas bearings, have broad applications, such as in microcompressors. However, some problems remain to be solved for the electrical performance analysis of PMSMs. For example, there is presently no related analytical model that can be used in rotor dynamics expression for this type of PMSM. This study aimed to establish theoretical models for electromagnetic force density and torque. The process involved both theoretical and experimental research. The analytic models of air gap magnetic density, electromagnetic force density, and electromagnetic performance were established for a PMSM with a parallel magnetized cylindrical permanent magnet. The analytic calculation was conducted, and the results of the analytic model were obtained. The analytical model of the electromagnetic torque and force can be applied in theoretical research on rotor dynamics. The model provides a theoretical basis and method for studying the influence of the electromagnetic load on rotor dynamics. A finite element simulation analysis of the electrical performance of the PMSM was carried out. An electrical performance experiment was conducted. The deviation between the experimental result and the theoretical value was less than 4%. This result indicated that the analytic models could be used in a dynamics analysis of compressors that are directly driven by a PMSM for application in engineering and industrial contexts.
