[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figures 1-4 The utility model discloses a kind of end covers of IP54 built-in self-fan cooling motor, including motor end cover 1, the slot hole is equipped on the motor end cover 1, ventilation window 2 is equipped in the slot hole, the inner side end surface of ventilation window 2 is equipped with dust screen 4, the periphery of dust screen 4 is equipped with cover plate 5, the cover plate 5 is fixed in the inner side end surface of ventilation window 2, and the cover plate 5 is used to limit dust screen 4;
[0023] Further, the periphery of ventilation window 2 is equipped with groove, rubber pad 3 that contacts motor end cover 1 is equipped in the groove, when ventilation window 2 is installed, it can extrude rubber pad 3, so that the sealing property of ventilation window 2 can be guaranteed.
[0024] Further, dust screen 4 uses nylon dust screen.
[0025] In the embodiment, ventilation window 2 is fixed in the inside of slot hole by first screw 6, so that ventilation window 2 can be easily assembled.
