Motor and compressor

The motor comprises a shell main body, the shell main body defines an installation space, the installation space is used for installing an electric control module of the motor, and at least part of the electric control module is fixedly arranged on the inner surface of the installation space. Therefore, the shell main body of the motor is provided with the mounting space for mounting the electric control module, so that the electric control module can be mounted in the mounting space of the shell main body, the miniaturization and integration design of the motor is realized, the occupied space of the motor is favorably reduced, and meanwhile, at least part of the electric control module is fixedly arranged on the inner surface of the mounting space; therefore, the shell main body can be used as a mounting structure of the electric control module, in the operation process of the motor, the shell main body can be used as a cold source due to flowing of the refrigerant and can cool the operation of the electric control module, the mounting structure and a heat dissipation module do not need to be independently designed for the operation of the electric control module, and the production cost of the motor is reduced.
