YKK系列高效高压三相异步电动机的优化设计

Optimal design for the induction motors with high-efficiency and high-voltage of YKK series

按多规格电机共冲片的设计原则,以追求各规格电机的有效材料成本最低和运行效率最高为混合目标,建立了适用于系列电机优化设计的数学模型。结合电机设计的工程实际,对模拟退火算法进行了适应性的改进。应用所建立的模型和改进算法,对新型YKK系列中型高效高压电机进行了整体优化。计算结果表明,整个系列内各规格电机的效率都提高了1%以上,达到或超过高效电机标准。同时新系列型谱中不仅电机的规格数和容量有所拓展,与原系列相比相同容量的电机被安置在更低的中心高内,电机有效材料的用量也平均减少20%以上。即使考虑到新设计采用了好的导电、导磁和绝缘材料,优化设计的效果还是显而易见的。优化设计结果已经用于实际生产。

The mathematic model was established which is suitable for the optimal design of series motors according to the design rule in which several motors are of same core stamping.The lowest effective material cost and the highest efficiency for the every motor were taken for the mix objective.The Simulated Annealing Algorithm was improved in light of the engineering practice of the electric machine design.The integral optimization was made for the new induction motors with high efficiency and high voltage of YKK series.The results show that the efficiencies of all motors in the new series are increased more than 1%,reach or excess the standards of the high-efficiency motors.On the other hand,the number and the rated powers of the motors in new series are expanded.The motor with same rated power is put into smaller frame in new series than old series.The effective materials used for the motors are reduced more than an average of 20%.Even if the better materials of conductor,core and insulation used in the new design are taken into consideration,the effect of the optimum design is obvious.The optimal design results have been applied in the practice engineering.
