Electric traction drive

Abstract

The paper considers electric traction drive with the field regulated reluctance machine (FRRM). The FRRM principles of operation and main advantages compared with asynchronous machine and synchronous reluctance machine are presented, disadvantages are marked. Mathematical model of the drive with FRRM is described; adequate accuracy is proved by the statistical data processing. The paper presents electric drive operating point determination in the static mode, transient model analysis, which takes into account electrical, electromechanical and mechanical processes of electric traction drive, present the first stage of optimization. The second step explains a method of increasing the maximum speed of the drive. The third stage is associated with optimization of FRRM features with over-torque. Therefore, the drive is obtained with improved weight and dimension characteristics, overload capacity, which meets the requirements of the haulers. Weight-size parameters optimization, three-stage characteristics optimization estimate the most favorable parameters of the control system and the motor. The explanatory drawings are given in the article.
