“…The whole structure of the UHSEAC is shown in Figure 1, which is mainly composed of the UHSPMSM and supercharger. Because the UHSPMSM has the advantages of high efficiency and small size [29,30], it used to be the power source. The UHSPMSM is mainly composed of the housing, stator, and rotor [31][32][33].…”

The ultra-high-speed electric air compressor (UHSEAC) is affected by the electromagnetic torque components of the ultra-high-speed permanent magnet synchronous motor (UHSPMSM) during wide-range speed regulation, resulting in intense speed fluctuation. Electromagnetic torque components are generated by the effects of permanent magnet field harmonics, stator slotting, and current harmonics. It is very important to conduct simulation comparisons and theoretical descriptions of different sources of pulsation factors. In this paper, firstly, the electromagnetic torque model of UHSPMSM with a rated speed of 80,000 rpm is constructed and verified by an experimental bench. Secondly, the electromagnetic torque components of UHSPMSM are extracted on the basis of the electromagnetic torque model. Finally, the electromagnetic torque components’ characteristic law is investigated under different ultra-high-speed operating conditions. The results show that under ultra-high-speed operation, the frequency and amplitude of electromagnetic torque components become larger with increasing speed. And the amplitude of electromagnetic torque components becomes larger with increasing torque. This paper constructs the observation object of the high-frequency state observer and does the preliminaries for the design of the UHSEAC controller.

“…It is important to achieve a high filling factor of the coil side cross-section with copper and to limit eddy currents in the conductors [15][16][17]. Despite these disadvantages, classic windings are still commonly used in many types of coreless electrical machines [18,19]. The development of new soft and hard magnetic materials, insulating materials or conductive materials, including hightemperature superconducting materials, has had a major impact on the development of electrical machines [20][21][22][23].…”

The paper presents a new cost-effective magnetic circuit structure of a coreless permanent magnet synchronous motor (PMSM) with 16 poles and 12 coils for a mass production fan drive unit. 2D and 3D numerical models of the coreless PMSM were developed. Optimisation calculations were carried out using the field model of the machine. Multistage calculations were performed using the professional FEM package, ANSYS Maxwell and the author’s proprietary finite element method (FEM) code. On the basis of the conducted tests and analysis of the obtained results, the “optimal” magnetic circuit structure of the PMSM motor was selected. The prototype motor was subjected to measurement to verify the developed models and the proposed design approach that takes advantage of finite element analysis (FEA).

“…Furthermore, permanent magnet synchronous motors (PMSMs) find extensive use in various industrial applications due to their high torque density and efficiency [3]. Unlike brushless DC (BLDC) machines, which exhibit trapezoidal EMF voltage, PMSMs generate sinusoidal EMF voltage [4,5]. Additionally, sinusoidal-type PMSMs exhibit lower torque ripple compared to their trapezoidal-type counterparts [6].…”

Electric motors with a double air-gap structure offer increased power or torque density compared to their single air-gap counterparts, achievable through double-stator or double-rotor configurations. In a previous study, the authors proposed a double-stator permanent magnet synchronous motor (PMSM) with a magnetic screen placed in the middle of the rotor to isolate the outer and inner motors. However, the analysis of the magnetic screen was not provided in that study, as the design was arbitrarily chosen. This research focuses on the effects of the magnetic screen size and selects the appropriate dimensions for optimal motor performance. Finite element analysis (FEA) is employed to assess the electromagnetic characteristics of the screen. Subsequently, the motor is manufactured and tested. The results show that the chosen magnetic screen size contributes to significant efficiency improvements. In particular, the motor achieved an efficiency of 95.2% during the qualification test, surpassing the efficiency obtained in the previous study.
