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.

Centrifugal compressors are widely used in different fields. Their design requires high performance and a wide operating range, where, at lower mass flow rates, unstable flow dynamic phenomena occur, which are extremely harmful and, at the same time, complex to fully understand. This review paper presents the main research from the last 40 years on the subject of instability in centrifugal compressors, aiming to clarify the main (sometimes contradictory) causes, classifying them according to the component in which they are triggered or the interaction between them. Importance is given to works that develop criteria for the identification of the stability limit with simplified models. The main techniques used to extend the stability limit are also presented by distinguishing between passive and active fixed-flow control methods; moreover, the main works on variable geometry techniques are reported, showing the advantages and disadvantages of their use. Finally, an overview of the innovative applications of centrifugal compressors, such as fuel cells, is presented. The aim of this review is to highlight the continued interest in this field of study and provide the tools to understand the different unstable mechanisms and techniques used to extend the operating limit.

Due to its advantages of high efficiency, high power density at low temperature, fast start-up and zero emission, fuel cells are of great significance in automobile drive application. A car powered by electricity generated by an on-board fuel cell device is called a fuel cell vehicle (FCV). Fuel cells have a large demand for heat dissipation, and the layout space of automotive cooling modules is limited. Based on this situation, a parallel arrangement of multiple radiators is proposed. Using numerical simulation means to verify and optimize the designed multiple circuits cooling system (MCCS), from the original layout scheme based on the Taguchi method to establish the objective function of the reliability design of the MCCS, select A2/B1/C1/D2/E1/F1. In the scheme, the outlet temperature of the fuel cell is finally reduced to 75.8 °C. The cooling performance is improved, and the spatial layout of the individual cooling components can also be optimized. The whole vehicle experiment was carried out under four working conditions of full power idling charging, half power idling charging, constant speed of 40 km/h and constant speed of 80 km/h, to verify the cooling performance of the MCCS and to prove the effectiveness of the MCCS designed in this paper.
