High-speed motor with cooling structure

The invention provides a high-speed motor with a cooling structure. The front part of a shell is provided with a front end cover and the rear part is provided with a rear end cover; a rotation shaft is concentrically arranged inside the shell; the front end and the rear end of the rotation shaft perform position fixing through a front bearing and a rear bearing respectively; the front end of the rotation shaft passes through the front end cover and extends out; the middle part of the rotation shaft is provided with a rotor; the position, corresponding to the rotor, on the inner wall of the shell is provided with a stator; a cold storage interlayer formed by the shell in a two-layer structure is internally provided with a cold storage liquid; the rear side of the shell is also provided witha first circulation pipe communicated with the cold storage interlayer; the first circulation pipe is arranged in the rear end cover; the first circulation pipe is provided with a first circulation pump and a first refrigerating mechanism; the rotation shaft is internally provided with two symmetrically-arranged and communicated hollow channels, the hollow channel is internally provided with thecold storage liquid, the hollow channel is communicated with a second circulation pipe at the rear end of the rotation shaft, and a second circulation pump and a second refrigerating mechanism are symmetrically arranged on the second circulation pipe. The high-speed motor with the cooling structure has the beneficial effect of quick cooling speed.
