The invention provides a compressor. The compressor comprises a stator, a support structure, a main shaft, and a rotor arranged on the main shaft; and the main shaft is rotationally supported on the support structure. The compressor further comprises a fluid channel for spraying a cooling fluid between opposite surfaces of the main shaft and the support structure, between opposite surfaces of the support structure and the end surface of the rotor and/or between opposite surfaces of the stator and the rotor. The compressor is provided with the fluid channel; and the cooling fluid can be sprayed between the main shaft and the support structure, between the support structure and the end surface of the rotor and between the stator and the rotor through the fluid channel, so that the temperatures of the main shaft, the support structure, the rotor and the stator can be kept in a certain range, the matching precision among all parts of the compressor is guaranteed, and the service life of the compressor is prolonged. The invention further provides a control method of the compressor.
