Abstract

An embodiment of the invention provides an air-water cooling high-power permanent magnet traction motor with a hanging structure. The air-water cooling high-power permanent magnet traction motor comprises a machine shell, a stator assembly and a rotor assembly. The machine shell surrounds to form an installation space for installing the stator assembly and the rotor assembly; an air cooling channel communicated with the installation space is formed in the machine shell; the rotor assembly comprises a rotating shaft; when the rotating shaft rotates, the blades on the rotating shaft are driven to rotate, and then air in the installation space is driven to flow into the air cooling channel; in the flowing process of the air, heat of a high-temperature area in the installation channel is absorbed, and heat is released to a low-temperature area, so that heat distribution of all the areas in the installation channel is balanced; and meanwhile, air exchanges heat with the machine shell when flowing in the air cooling channel, heat carried by the air is transmitted through the machine shell and dissipated to the outside atmosphere, and therefore uniform cooling of the interior of the high-power permanent magnet traction motor is achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-power permanent magnet traction motor. Background technique [0002] Traditional high-power permanent magnet traction motors are mostly used in the operation of rail vehicles. The motor includes a housing, a stator, a rotor and a main shaft. The stator is arranged on the inner wall of the housing, and the rotor is connected to the main shaft. The rotor is arranged inside the stator; When the power is turned on, the rotor rotates, which in turn drives the main shaft to rotate, and a large amount of heat is generated inside the motor during operation. [0003] In the related art, in order to avoid the accumulation of heat generated when the high-power permanent magnet traction motor is working, resulting in excessive temperature, a cooling channel is often provided between the inner wall and the outer wall of the housing, and the first opening of the cooling channel is set on...
