“…Deshalb beziehen sich vorhandene Degradationsmodelle zumeist auf Komponenten des Elektromotors, welche am häufigsten zum Ausfall des gesamten Subsystems führen. In [48] wurden diese Komponenten einschließlich ihrer Degradationsphänomene definiert, auf welche alle neun verschiedenen in [48][49][50][51][52] gefundenen Degradationsmodelle Bezug nehmen. Maßgeblich sind demnach:…”

“…Wälzlagern, welche auf umfangreichen Messdaten und Erfahrungen beruhen, aus denen sich der Einfluss einzelner Einflussgrößen aber nur eingeschränkt ableiten lässt [20], [52]. Entscheidend für die Degradation von Isolatoren bei den in [48][49][50][51] betrachteten Modellen ist die Temperatur, deren Einfluss meist in Anlehnung an die Arrheniusgleichung modelliert wird. Für Spulenisolationen werden daher Messwerte aus thermischen Lebensdauerversuchen der verwendeten Materialien benötigt.…”

Lifetime heterogeneity results from differing lifetimes of subsystems and components (entities) within a system and is a key criteria to evaluate life cycle options, like upgrading or reuse, for more sustainable products. In early design stages of products for new use cases only limited information for lifetime prognosis are available. This paper proposes a concept to forecast the lifetime of products without experimental data. For purpose a systematic review is conducted to analyze degradation models of Li-ion batteries and electric motors. By analyzing and comparing similarities regarding influencing factors and their impact, fundamentals for degradation modelling are derived. Based on these findings a procedure for lifetime prediction in early design stages for emerging products, like Li-ion batteries and electric motors, are derived.

“…An Y. et al investigated the temperature field of a single-phase canned induction motor (CIM) used in vacuum pumps using three-dimensional finite element method. By comparing it with experimental data, it is found that the finite element method exhibits a high accuracy [12]. In [13], a three-dimensional finite element model with electromagnetic-thermal unidirectional coupling was established for a vacuum pump switch reluctance motor, and this model was used to analyze the motor temperature field.…”

Accurate temperature prediction is vital for the canned permanent magnet synchronous motor (CPMSM) used in the vacuum pump, as it experiences severe heating. In this paper, a novel motor temperature calculation method is proposed, which takes into account the temperature impact on the heat transfer capacity. In contrast to existing electromagnetic-thermal coupled calculation methods, which solely address the temperature effect on the motor electromagnetic field, the proposed method comprehensively considers its impact on motor losses, permanent magnet magnetic properties, thermal conductivity, and heat dissipation ability of motor components, resulting in a motor temperature simulation that closely resembles the actual physical process. To verify the reliability of the proposed temperature calculation method, a 1.5 kW CPMSM was chosen as the research subject. The method was used to analyze the temperature distribution characteristics of the motor and assess the impact of ambient temperature on motor temperature rise. Furthermore, a prototype was fabricated, and an experimental platform was established to test the motor temperature. The results demonstrate good agreement between the calculated results obtained using the proposed method and the experimental data. This research not only provides a theoretical foundation for optimizing the design of the CPMSM but also provides valuable insights into its operational safety and reliability.

“…Guo et al [19] proposed the MTC analysis method of motors, integrating calculated loss into fluid analysis based on fluid-solid coupled heat transfer, and subsequently returning the calculated temperature back to the electromagnetic field. Amadou Tinni et al [20] calculated component temperatures by plugging motor losses into a "lumped heat network". Wang et al [21] simplified the space between the stator and rotor into a hollow cylinder to explore the temperature distribution of motor pumps.…”

The integrated design of the motor and axial piston pump eliminates the coupling structure, resulting in a compact and lightweight motor-pump structure. The challenge of motors overheating has always been a major concern. To address this issue, the hydraulic oil throughout the motor pump is utilized for cooling the high-speed motor, effectively improving the power density and heat dissipation capability of the hydraulic power unit. This integrated design approach has successfully resolved the significant issue of overheating motors, leading to enhanced performance of the hydraulic power unit. To address this concern, the entire motor pump’s oil is utilized to cool the high-speed motor. Consequently, the thermodynamic prediction of high-speed motor pumps has become increasingly important. In this study, the impact of motor heat generation on hydrodynamics is analyzed, and the heat transfer of the motor pump is investigated using the control volume method. Furthermore, thermodynamic models of hysteresis loss, eddy current loss, alternating current loss, churning loss, and throttling loss are established for the oil-immersed motor pump. The change in oil viscosity is also considered. The instantaneous temperature change rule of the oil within the oil-immersed motor pump is derived. Additionally, the influence of various working conditions such as pressure and speed on the temperature of the motor pump’s key node is examined. The experimental results indicate the accuracy of the thermodynamic calculation, and the significant effect of motor loss on the leakage temperature.
