“…Special attention was paid to the effect of the angle of attack of the incoming flow at the pipe entrance, which has never been studied by the previous investigators. The geometrical setup is close to the real electrical motor geometry [1,10]. The investigations will be performed using CFD methodology and validated against experimental data of Baudoin [10].…”

“…Experimental data elucidated a clear trend of the local Nusselt numbers to increase with an increase in uP'H. The data of Stephenson [8] for the mean Nusselt number for the initial length of the pipe were approximated by the empirical equation (maximum deviation of ± 14%): (1) where L/D= 19.3, H/D = 25.\9, Re = 5500 to 33000; Re" = 600 to 4000; Ro<0.75; co = 280 to 2200rpm. In the absence of rotation, the mean Nusselt numbers in the initial region were described by the equation: = 0.031 Re' ,0.79…”

“…Rotating circular straight pipes are wide-spread in air cooling systems of many industrial applications, for instance, in electrical machines used in railway transport, aircraft electric generators etc., see recent investigations [1][2][3] and a review paper [4]. As applied to a moving train, electrical motors are often completely shrouded to prevent the dust particles from penetrating inside the motor.…”

Cooling of electrical machines is nowadays of high interest in order to improve their efficiency. In railway applications, electrical motors can be shrouded in order to avoid particles to be deposited inside. To ensure a satisfactory cooling, pipes are placed inside the rotor and are thus rotating. Improvements in convective heat transfer inside the rotating pipes were numerically investigated. Model was first validated against experimental data and after that several geometry modiflcations were tested. Influence of the angle of attack of the fluid at the inlet to the pipe was discussed and it was shown that heat transfer can be significantly increased near the pipe inlet. In addition to that changing a circular pipe with an elliptical pipe was investigated in two ways: fixing the same hydraulic diameter or the same equivalent diameter. It was shown that the cooling efficiency can be significantly increased. The best overall heat transfer enhancement of about 45% exhibited elliptic pipes located orthogonal to the rotation radius and having the same crosssection as the reference circular pipes. Results can be used by designers of electrical machines in order to choose the best cooling strategy.

“…Squirrel cage IMs (SCIMs) are brushless alternating current (AC) machines fed by sinusoidal voltagescurrents, which are widely applied in industrial applications and for electrical propulsion systems [6,56] since they offer high simplicity, low cost, reliability, robustness, low torque ripple, low maintenance needs and ability to operate in harsh environments. SCIMs are being applied in some commercial FEVs including electric cars, buses and light trucks [9].…”

Several factors including fossil fuels scarcity, prices volatility, greenhouse gas emissions or current pollution levels in metropolitan areas are forcing the development of greener transportation systems based on more efficient electric and hybrid vehicles. Most of the current hybrid electric vehicles use electric motors containing powerful rare-earth permanent magnets. However, both private companies and estates are aware of possible future shortages, price uncertainty and geographical concentration of some critical rare-earth elements needed to manufacture such magnets. Therefore, there is a growing interest in developing electric motors for vehicular propulsion systems without rare-earth permanent magnets. In this paper this problematic is addressed and the state-of-the-art of the electric motor technologies for vehicular propulsion systems is reviewed, where the features required, design considerations and restrictions are addressed.
