“…Since the focus of this paper is on the steady‐state temperature field of the motor, the temporal aspect in the heat conduction governing equation is not considered. For the solid domain, the detailed descriptions of the heat conduction equation for the 3D solved model of the motor are expressed as [17]:

({, \begin{matrix} right leftthickmathspace.5em \\ \frac{\partial}{\partial t} (λ_{x} \frac{\partial T}{\partial x}) + \frac{\partial}{\partial t} ()(, λ_{y} \frac{\partial T}{\partial y}) + \frac{\partial}{\partial t} (λ_{z} \frac{\partial T}{\partial z}) = - q_{v} \\ {(|, \frac{\partial T}{\partial n})}_{S 1} = 0 \\ {(|, λ \frac{\partial T}{\partial n})}_{S 2} = - α false(T - T_{f} false) \end{matrix})

where λ x , λ y , λ z are the heat conduction coefficients in the x , y , z direction (W/K·m), q v is the heat source density (W/m 3 ), S 1 is the thermal insulation surface, S 2 is the heat transfer surface, α is the heat transfer coefficient (W/m 2 ), T f is the fluid temperature around heat transfer surface (K).…”

Ding et al have been dedicated to analysing the three‐dimensional (3D) CFD model of a PMSM with cooling ribs and junction boxes with the use of ANSYS Fluent software package [17, 18]. The above studies reveal the effectiveness of CFD in solving the fluid and thermal issues of HSPMM.…”

Due to the merit of very‐short end turns, Gramme‐ring windings are widely used in high‐speed permanent‐magnet motors (HSPMMs). This study investigated the thermal issues of a 300 kW, 12,000 rpm Gramme‐ring‐winding HPSMM with housing water jacket and forced air cooling, based on the computational fluid dynamics (CFD) and numerical heat‐transfer calculations. The reasons that cause the overheat of the prototype in the experimental test are thoroughly analysed. The high wind resistance of air gap as the ventilation duct and the large interface gap between the stator lamination and housing water jacket is thought to be the main reasons. Then improvement of the ventilation structures is studied to decrease the wind resistance. Besides, the modification of water channels is also investigated to avoid the influence of a large interface gap on the water cooling performance. Finally, a new cooling structure, combining the slot ventilation ducts and inside water channels, is proposed for the HSPMM with Gramme‐ring windings. With the new cooling structure, the temperature rise of the motor is decreased, and the power density can be increased.

Temperature rise is an essential factor affecting the safety operation of electric machines. An appropriate solving domain is the first step to consider when calculating the temperature rise. However, the effect of solving domain setting on the calculation results of electric machine temperature rise has not been deeply discussed. In this paper, a 3MW permanent magnet wind generator is taken as an example. Based on the electrical and numerical heat transfer theories, two different solving domain models are established to compare the flow thermal characteristics of the internal and external ventilated paths. The fluid velocity changes in external ventilated path, the central section temperature rise and the velocity trace distribution of the internal ventilated path are compared in detail. Furthermore, the temperature rise of each component is analyzed. It is found that the fluid development in the generator is affected by solving domain selection. The results can provide a reference for accurate calculation of temperature rise of permanent magnet wind generator. INDEX TERMS Flow-thermal coupling, permanent magnet wind generator, solution region setting, temperature field.
