[19], El-Refaie developed a thermal model for the interior permanent magnet (IPM) synchronous machine based on the proposed thermal model of Lindstrom and only altering the rotor LP circuit and suffer from the same drawbacks of Lindstrom model. This paper presents a detailed analytical thermal analysis of a SynRM.
High-speed permanent magnet synchronous motors (PMSMs) are usually started with the hybrid low-speed open-loop and high-speed closed-loop control mode. However, low-speed open-loop control produces large starting current, or even current overload, resulting in demagnetization and motor damage. Therefore, there is an urgent need to develop a high . Maximum torque of permanent magnet synchronous motor (PMSM) is determined by winding insulation and permanent magnet (PM) temperature constraints. In this paper, through the co-simulation model, the loss of the motor with the excitation of the pulse width modulation (PWM) voltage source is obtained. For the liquid-cooled interior PMSM for electric vehicles, a .This paper presents a review of the losses and thermal analysis of permanent magnet assisted synchronous reluctance motors. Various types of solutions for critical parts of heat extractions and different empirical correlation for determination of each part are presented in details. Finally the experimental methods for determination of the critical parameters are presented. In this . Thermal analysis and cooling solutions must be identified in order to augment the lifespan of the permanent magnet synchronous electric machine (PMSM). The voltage unbalance causes adverse sequential voltage in the air gap, which turns flux against the motor shaft and also appears to produce massive currents.
As a submersible permanent magnet synchronous motor (SPMSM) must function in downhole high temperature crude oil for long periods of time, the accurate prediction of its temperature rise is . The analysis of the Permanent Magnet Synchronous Machine, especially with the high power density and more efficient cooling system is of great practical significance to lower greenhouse gas, to . This paper presents a thermal analysis of permanent-magnet synchronous reluctance machines (PM-SRM). Particular focus is put on the rotor and two lumped parameter (LP) thermal models of the rotor are implemented and evaluated. The results of the two LP thermal models are compared to thermal simulations using the finite element method (FEM). . Thermal analysis with lumped parameters could be applied as a preliminary approach to predicting the approximate thermal performance of large electrical machines. To date, research papers have been published describing lumped parameter thermal models of electrical machines equipped with indirectly cooled multi-turn coils [11] , [12] , [13] .
Thermal simulation has been used for the thermal analysis of laser-induction hybrid manufacturing. Farahmand and Kovacevic [9] proposed a 3-D thermal model to elucidate the effect of substrate inductive pre-heating on the morphology of a molten pool and its corresponding microstructure. A steady-state thermal analysis with the rated thermal loading predicted a maximum temperature in the liquid-cooled tooth-coil winding under forced water cooling of 81 °C for a cooling water flow of 1 m/s. The thermal results for both the analytical thermal model and the . Acknowledgements The rotor temperature rise of high voltage line start solid rotor permanent magnet synchronous motors (HVLSSR-PMSMs) may be too high while operating, which properly cause thermal demagnetization .
This article reports an investigation on the thermal reactivity of nano-aluminum powder (NAP) in the air. We performed tests on the metallic powder in synchronous thermal analysis at four heating rates of 5, 10, 15, and 20 °C min−1. Given the polymorphic phase change of aluminum, the oxidation process of NAP was divided into four stages. The results showed a .

STA/TG-DSC. Simultaneous Thermogravimetry – Differential Scanning Calorimetry. Simultaneous Thermal Analysis (STA) is based on standards, e.g., ISO 11358, ASTM E793, DIN 51004, DIN 51006, DIN 51007. It generally refers to the simultaneous application of Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) to one and the same sample in a single instrument. The traditional electromagnetic–thermal bidirectional coupling model (EMTBCM) of permanent magnet synchronous motors (PMSMs) requires a long time to solve, and the temperature-induced torque change is not accounted for in the finite element (FE) numerical calculation of the EM field. This paper presents a precise and efficient EMTBC reduced-order .
