The present invention relates to a motor, and particularly to a variable-frequency speed-regulating asynchronous traction motor for the high-speed AC passenger locomotive. The invention settles the problem that no large-power, high-rotating-speed and high-voltage motor exists at present. The end plane at the non-transmission end of the rotating shaft is provided with a shaft brush holder. The copper conducting bar and the copper end ring are made of high-strength alloy copper CuCrZr. The protecting ring is made of high-strength alloy steel 50Mn18Cr5. The end cap is provided with a cylinder sleeve. The bearing at the transmission end of the rotating shaft is sleeved with an inner cap of the bearing. The back side of the bearing is provided with a pinion. The cylinder sleeve is provided withan arc transmission opening, an oil inlet through opening, a main oil return opening and an auxiliary oil return opening. The inner cap of the bearing is provided with an oil through opening. The outer cap of the bearing is provided with a groove. The shaft sleeve part of the pinion is fixed with an oil striker. The back side of the oil striker is provided with a back inner sealing ring. The backinner sealing ring is fixed with the protecting cap and furthermore the inner ring of the back inner sealing ring is provided with an annular seal groove. The lower part of the annular seal groove isprovided with an oil leakage channel. The variable-frequency speed-regulating asynchronous traction motor for high-speed AC passenger locomotive can operate under high rotating speed and satisfy thepower requirement of the high-speed AC passenger locomotive.
Description
technical field [0001] The invention relates to a motor, in particular to a high-power, high-speed, high-voltage asynchronous traction motor, in particular to a frequency-variable speed-regulating asynchronous traction motor for high-speed AC passenger locomotives. Background technique [0002] In order to meet the requirements of the leap-forward development of Chinese railways, it is an inevitable trend of technological development that railway locomotives adopt AC drive technology. The asynchronous traction motor is the key component and device in the AC drive locomotive. The AC drive locomotive is powered by asynchronous traction motor with variable frequency speed regulation, and drives the locomotive wheel set through the gearbox. Therefore, high-speed railway passenger locomotives require high-speed traction motors, and at the same time output torque equivalent to that of freight locomotives, which requires that traction motors of passenger locomotives output greater...
