The invention discloses an assembly structure for a compressor motor and a housing, and relates to the technical field of compressors. The assembly structure for the compressor motor and the housing comprises sleeve rings which are fixedly connected on the inner wall of the housing; the sleeve rings comprise inner rings; and the motor is fixedly arranged between the two inner rings of the two sleeve rings. Meanwhile, the invention further discloses a compressor comprising the assembly structure. According to the assembly structure, a thermal sleeving process of the motor and the housing is avoided, the stress problem of thermal sleeving assembly is solved, motor deformation is reduced, manufacturability is improved, a through-flow area of the compressor is increased, ventilation effect is strengthened, temperature rise in an operation process of the motor is reduced, and performances of the motor are improved; besides, in the presence of the sleeve rings, the motor does not need to be great, usage of silicon steel sheets is also reduced, iron loss of the motor is reduced, and production cost of the motor is reduced.
