specific Embodiment approach 1
[0024] Specific implementation mode one, such as figure 1 and figure 2 As shown, the arrow in the figure shows the flow direction of the cooling gas in a switched reluctance motor with a water injection winding and a shaft-diameter-circumference multi-directional self-circulating ventilation system. A switched reluctance motor with a water-injection winding and a shaft-diameter-circumference multidirectional self-circulating ventilation system according to the present invention includes a stator core 1, a rotor core 2, a rotor shaft 3, a stator copper winding 4, and a stator direct cooling water pipe 5. Rotor direct cooling air passage 6, stator direct cooling air passage 7, stator direct cooling water driving device 8, sheet heat conduction plate 9, machine base 10 and bearing 11;
[0025] The rotor shaft 3 is installed on the base 10 through the bearing 11, the rotor core 2 is installed on the rotor shaft 3, the stator core 1 is installed on the inner wall of the base 10, ...
specific Embodiment approach 2
[0031] Specific implementation mode two: combination image 3 Describe this embodiment. The difference between this embodiment and Embodiment 1 is that the inlet area of the rotor axial direct cooling air passage 6-1 is increased, and the inlet area is 130 mm. 2 ~400mm 2 , the cross-sectional area of the rotor axial direct cooling air duct 6-1 gradually decreases along the axial direction, which can increase the fluid flow rate entering the rotor core 2, speed up the circulation speed of the cooling gas in the switched reluctance motor, and improve the cooling rate of the cooling gas. The utilization rate of the switched reluctance motor reduces the temperature of the stator core 1, rotor core 2 and stator copper winding 3 inside the switched reluctance motor. Other components and connections are the same as those in Embodiment 1.
specific Embodiment approach 3
[0032] Specific implementation mode three: combination Figure 4 Describe this embodiment, the difference between this embodiment and Embodiment 1 is that the number of stator direct cooling air passages 7 in the stator core 1 has been increased, the cooling effect of the yoke of the stator core 1 has been enhanced, and the internal temperature of the stator core 1 has been improved. The surface heat dissipation coefficient effectively improves the ability of the cooling gas to take away heat from the stator core 1 and further reduces the temperature of the stator core 1 . Other components and connections are the same as those in Embodiment 1.
