Выбор типа тягового электромеханического преобразователя энергии для пригородного электропоезда

Abstract

B is currently in the development of new electric rolling stock (ERS) raises the question of choosing the concept of traction drive. In this paper the method of selecting the type of traction electromechanical transducer on the basis of systematic criteria for including the electric power consumption, the average speed of its movement and the proposed indicator of efficiency - the ratio of energy converted ERS of electrical energy into mechanical energy traction or braking to the maximum possible energy which can be implemented under the terms of wheel-rail contact at the highest possible speed on the section of the route. Defined rational types of electromechanical transducers for commuter trains at different speeds. Found that for maximum speeds 50, 90, 120 and 140 km/h is advisable to choose a synchronous motor with permanent magnet excitation for other considered speeds, 60, 70, 80 , 100 and 110 km/h, asynchronous traction motor.
