Within the overall car alternator fan temperature rise test analysis
The diameter at the same time, lengthening the stator coil end part length, the stator coil resistance decreases, increasing the cooling area, to strengthen efforts to end the wind, the temperature rise by the generator 157. C down to l17 ℃. Internal fan cooling the whole alternator diagram of the ventilation motor is 4}}}} 3 only increased on the basis of the motor stator coil end size, on the one hand, the stator coil resistance increases,ralph lauren italia (http://www.ralphlauren-italia.com), the motor heat to increase; the other hand, As the end of Ministers increased,ralph lauren shop (http://www.ralphlauren-pascher.net), increasing the cooling area of the stator Lun, strengthen efforts to end the ventilation, heat transfer faster, reduce the motor temperature rise. Simple calculation is as follows: Let 3}}, 4}} motor heat generated per unit time, respectively Q, Q, the same output current, temperature stability, the table was the: R32 = 0.0755Q, R42 = 0.0785Q, then: Q3 = falling R32 = 00755-1.04 a = a = lI / l ● - ● u ● Piece Goods 1 == × 1.04 = 0.83At25Q3253 from the table, At3 = l17 ~ C, into the above equation, the solution was: At4 = 97-3 ℃ That is to say, four motor 3 based on the motor end of the stator lengthened, the motor temperature down to 97-3. C. The actual temperature is 92.6 ℃,mbt scarpe prezzi (http://www.scarpe-mbt.org/), the difference is because in addition to 2 ≠} motor analysis, the end of the strengthening of ventilation, but also a very important one. From the theoretical calculations and test results can be obtained, the appropriate degree of Ministers extended stator windings, cooling capabilities, enhanced heat than the stator windings, the motor temperature rise greater impact. However, by increasing the length of the stator winding end way to lengthen minister degrees,abercrombie madrid (http://www.abercrombie-madrid.com), on the one hand increases the motor losses, it also causes higher costs. If the improved assembly process, line of plastic embedded in the stator windings, the overlapping ends of the coil into a layer by layer staggered into a trapezoidal from fans recently at the thinnest, so that both the stator windings without increasing the length, based on the extended Minister of degree terminal, but also improve the ventilation of the stator winding condition, into the ... step to improve the motor cooling ability. 5 summarizes our research and development of the power of the whole alternator fan, through appropriate increases the diameter of the stator windings to reduce motor wear and tear; appropriately extended the length of the stator end windings to enhance the motor cooling, all of significantly reduce the effect of generator temperature. In actual production, considering the cost, the assembly process and other factors, the latter is more promotional value. Our follow-up development, improvement of power within the overall alternator fan, have adopted this approach in addressing the issue of motor temperature rise, and achieved good results. In addition, changes in the motor air duct, fan blades to improve the shape, size and distribution, but also to improve the generator's ventilation efforts to reduce motor temperature, an important way to reduce the noise generator. This paper not to be further explored.
