Embodiment Construction
[0021] Such as Figure 5 As shown, a double-speed high-voltage explosion-proof three-phase asynchronous motor adopts non-double pole design, which consists of stator 3, rotor 4, bearing device 1, end cover 9, and end cover 8. The rotor 4 is placed in the front and rear two bearing devices 1, the bearing device 1 is connected with the front and rear end covers 9 by bolts respectively, the front and rear end covers 9 are connected with the stator 3 by bolts, the end cover 8 and the end cover 9 are connected by bolts, the end cover 9, the outer fan 11, The stator 3 forms an open-loop external air path; the rotor 4 is composed of a rotor iron core, a squirrel cage, a shaft, a key, an inner fan 10, an air guide tube 13, and a balance ring, the squirrel cage is placed on the rotor iron core, and the rotor iron The core and the shaft adopt an interference fit and are connected by a key. The air guide tube 13, the balance ring, and the inner fan 10 all adopt an interference fit with t...
