Built-in outer rotor mixed excitation mining elevator comprising cooling structure

The invention discloses a built-in outer rotor hybrid excitation mining elevator comprising a cooling structure. The built-in outer rotor hybrid excitation mining elevator comprises a motor main body and a cooling system, the motor main body comprises a rotor shell, a permanent magnet rotor, an electro-magnetic winding rotor, a stator, a motor base, a stator shaft, a left end cover and a right end cover; a permanent magnet cooling pipeline and an electro-magnetic cooling pipeline are arranged on the left side and the right side in the stator respectively; the cooling system comprises a cooling liquid tank and a gear pump, the cooling liquid tank is communicated with the stator shaft internal water inlet channel through the gear pump and a pipeline, and the stator shaft internal water outlet channel is communicated with the cooling liquid tank through a pipeline. The hybrid excitation motor is smaller in size and simple in structure, has the advantages of being wide in working range, high in starting torque, h
