“…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]. Slots are present on the inner surface of the stator, and three-phase excitation windings, a/b/c are erected in the slots.…”

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.

With the development of wind power generation, improving the accuracy of fault diagnosis in permanent magnet synchronous motor (PMSM) is crucial for reducing maintenance costs. This paper integrates signal analysis and machine learning algorithms, proposing an approach that combines the improved empirical wavelet transformation (IEWT) with the CatBoost algorithm to diagnose open-phase faults in PMSM. IEWT effectively suppresses the modal aliasing phenomenon caused by noise and spectral leakage in traditional empirical wavelet transformation, and the decomposition results can demonstrate the time-frequency characteristics of the fault signal used for training the CatBoost classification model. Experimental results indicate that the proposed algorithm achieves high overall accuracy in diagnosing open-phase faults in PMSM, with balanced performance across each category.
