End winding packaging type oil cooling structure applied to permanent magnet traction motor

The invention discloses a packaging type oil cooling structure applied to an end winding of a permanent magnet traction motor, and solves the problem that in the operation process of the permanent magnet traction motor, the temperature rise of the end winding is too high, and insulation is damaged. The outer side of the end winding is formed by adopting an epoxy resin material in a potting manner; the insulating resin material partition plate, the rotating shaft, the rubber ring and the end cover form a closed area, and the area is filled with transformer oil to form a closed oil tank. When the motor operates stably, the driving force of the rotating shaft of the motor is utilized to drive the centrifugal fan blades and the rotating shaft to rotate concentrically, then transformer oil between the centrifugal fan blades is thrown out in the radial direction, and due to the action of the baffle and the solid wall face, the transformer oil absorbs heat near an end winding and then returns to the area close to th
