The invention discloses a stator sealing stator structure and motor. The stator sealing stator structure and motor includes a motor body, a cooling box, a base, a stator core and a coil, wherein the cooling box is fixedly connected to the side surface of the inner surface of the motor body; the base is fixedly connected to the bottom of the inner surface of the motor body; the stator core is stuckin the surface of the base; the coil is wound around the surface of the stator core; and a top cover is mounted on the top of the motor body. By setting the top cover and arranging the top cover on the motor body, when the inner surface of the cooling box leaks, the liquid is first absorbed by the cylindrical absorption block, and then flows to the liquid collecting groove for accumulation, and when the liquid is close to the joint between the sealing bottom plate and the isolation cylinder, the liquid is absorbed by the disc absorption block, and finally the liquid passing through the connection gap between the sealing bottom plate and the isolation cylinder is blocked by the sealing ring, and then the sealing effect of the stator is achieved indirectly through sealing of the rotor by means of the cooperation between the above structures.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a stator sealing structure and a motor. Background technique [0002] With the development of motor technology and the increase of motor speed, the power density of the motor is increasing. The cooling of the motor winding has become the key technology for the increase of the power density of the motor. Long-term action of the medium, resulting in leakage or motor failure. However, most of the stators of motors on the market are not equipped with a sealing structure, resulting in leakage of the cooling medium and contact with the rotor, which is likely to cause safety accidents and needs to be improved. Utility model content [0003] The purpose of the present invention is to provide a stator sealing structure and a motor, which has the advantage of preventing the stator coolant from contacting the rotor after leakage, and solves the problem that most of the stators of motors o...
