Stator, motor and wind generating set

Abstract

The invention relates to a stator, a motor and a wind generating set, the stator comprises a base, a supporting part and a stator body, the base is provided with an annular cavity extending in the axial direction of the base and arranged in a sealed mode, a first opening and a second opening, the first opening and the second opening communicate with the annular cavity, and the supporting part is arranged in the annular cavity and connected with the base; the stator body is arranged in the annular cavity, the stator body comprises an iron core and a coil arranged on the iron core, the iron core and the base are arranged in a spaced mode in the radial direction, the annular cavity is divided into a first cavity and a second cavity through the supporting part, and the iron core is provided with a plurality of radial medium channels communicating with the first cavity and the second cavity; therefore, the cooling medium can be in direct contact with the iron core and the coil arranged on the iron core, heat loss is reduced, the contact area of the iron core and the cooling medium is increased, and cooling efficiency is improved.
