Embodiment Construction
[0041] An embodiment of the present invention provides a mine flameproof lifting device with a built-in permanent magnet motor. The device includes:
[0042] A shaft fixed to the ground;
[0043] Permanent magnet motor stator fixed on the main shaft;
[0044] a reel rotating relative to the main shaft; the reel circumferentially surrounds the main shaft;
[0045] a permanent magnet motor outer rotor fixed by webs and rotating relative to said main shaft;
[0046] The reel is connected with the outer rotor of the permanent magnet motor through the isolation disc;
[0047] The radial distance between the outer circumferential surface of the outer rotor of the permanent magnet motor and the inner wall of the reel is greater than a preset value.
[0048] For brevity of description, the stator of the permanent magnet motor is referred to as the stator, and the outer rotor of the permanent magnet motor is referred to as the outer rotor.
[0049] Here, the main shaft is fixed on ...
