The invention relates to a traction motor for an electric locomotive, and in particular relates to a high-power asynchronous traction motor for an alternating-current transmission rapid passenger transportation electric locomotive, which solves the problem that an existing traction motor adopted by the electric locomotive can not meet the operating requirement of the alternating-current transmission rapid passenger transportation electric locomotive. The high-power asynchronous traction motor comprises a stator part, a rotor part, an end cover part, a wiring part and a sensor part, wherein the stator part comprises a machine shell, a stator core, a stator winding, a driving end stator clamping ring, a non-driving-end stator clamping ring and a pulling plate; the rotor part comprises a revolving shaft, a rotor core, conducting bars, end rings, a driving end rotor pressing plate, a non-driving-end rotor pressing plate, a coupling, a round nut and balance tabs, and the end cover part comprises an end cover, a bearing, an outer bearing cover, an inner shaft sleeve, an inner sealing ring and an air outlet mesh enclosure. The high-power asynchronous traction motor provided by the invention is suitable for the traction of the alternating-current transmission rapid passenger transportation electric locomotive.
Description
technical field [0001] The invention relates to a traction motor for an electric locomotive, in particular to a high-power asynchronous traction motor for an electric locomotive with AC transmission and fast passenger transport. Background technique [0002] At present, in order to alleviate the passive situation of hard-to-get tickets for railway passenger transport, improve the passing capacity of railway express passenger transport, and meet the growing demand of passengers, railway passenger transport urgently needs to adopt AC drive express passenger electric locomotives with the ability to run quickly. Under the existing technical conditions, the traction motors used by electric locomotives are mainly divided into two types: one is the pulse current traction motors used by DC drive passenger electric locomotives, and the other is the high-power traction motors used by AC drive freight electric locomotives. Asynchronous traction motor. Practice has shown that the tract...
