Integrated motor, compressor and air conditioner

The utility model discloses an integrated motor, a compressor and an air conditioner, the integrated motor comprises a housing, a motor part and an electric control part, the housing is provided with a first chamber, a second chamber and a communication hole, the motor part is arranged in the first chamber, and the electric control part is arranged in the second chamber; and the communicating hole is at least communicated with the second cavity and is suitable for pumping out air in the second cavity. Therefore, air in the second cavity can be pumped out through the communicating hole, so that water vapor in the second cavity is eliminated, the phenomenon of condensation in the second cavity in the working process of the integrated motor is avoided, the electric control part can be prevented from being influenced by condensation while the electric control part is cooled through the shell with the low temperature, and the service life of the integrated motor is prolonged. The working stability and the use safety of the integrated motor are effectively improved.
