Stator structure and motor

A stator structure, comprising:

• an air duct housing;
• a fixing part, coaxially disposed in the air duct housing and configured to install a motor assembly, wherein a first end of the fixing part is provided with a mounting inlet configured to install an end cover;
• connecting components, disposed between the air duct housing and the fixing part, and configured to fix a relative position of the air duct housing and the fixing part;
• and
• a mounting end cover, disposed on a second end of the fixing part;
• wherein a position of the mounting inlet provided by the fixing part is on a same side as a position of a fan blade assembly disposed in the air duct housing;
• wherein an inner diameter of the fixing part at the first end is equal to an inner diameter of the fixing part at the second end, and is greater than an inner diameter of the mounting end cover at the second end;
• and an inner wall of the air duct housing is taken as a first surface configured to install a fan blade assembly, an inner wall of the fixing part is taken as a second surface configured to install a stator assembly, an inner wall of the mounting end cover is taken as a third surface configured to install a bearing, and the first through third surfaces are made in an one-time processing, thereby ensuring coaxiality of the air duct housing, the fixing part and the mounting end cover.
