Design Optimization of an Asynchronous Motor Used in Light Railway Traction
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2017, Vol 41, Issue 41
Abstract
The appropriateness of this work is provided by highlighting some aspects insufficiently treated in the areas of designing and dimensioning of asynchronous traction motors associated with light traction static converters. The traction system is aimed for the light railway vehicles. Through the usage of asynchronous motors supplied by independent converters, the performances concerning the traction and the electric braking system are improved, while the maintenance expenses are reduced. The newly designed motor is aimed for the traction system of a locomotive driv-ing a multiple unit train, while the parameters necessary for the analysis of the regenerative braking system are also ac-counted for. An algorithm for the optimal design of the asynchronous motor is developed, considering the main parameters as the electric and magnetic quantities, the manufacturing and operating costs. The motor dimensions are computed starting from the values of the electromagnet-ic quantities resulted in the optimization process. The opti-mization algorithm is realized in Mathcad, any parameter modification leading to a new motor model. The main objec-tive of the paper is to optimally design the asynchronous traction motor directly rotating the drive wheel of the elec-tric train. The motor design takes into account the statio-nary rated regime, with the speed adjustment within wide limits, frequent starts and stops.
