It is proposed a device for processing a continuous signal sampled at a fixed sampling rate to obtain a digital signal, the continuous signal comprising state monitoring data of a rotating element, the rotating element experiencing a change in rotational speed. Said means comprise:-segmentation means (15),-spectral analysis means (16),-filtering means (17),-first processing means (18),-memory (19),-second processing means (20), and-sampling means (21).

The application provides a reluctance motor and a reluctance motor for driving a compressor, comprising a shell; a stator and a rotor are arranged in the shell, and a rotating shaft is fixed in the middle of the rotor; a cooling cavity is arranged in the shell wall, and the cooling cavity is used for cooling liquid flow; heat dissipation mechanisms are fixed on both sides of the rotor, a liquid delivery part is arranged on one side of the heat dissipation mechanism, the liquid delivery part extends into the cooling cavity; a plurality of liquid brushing rings are arranged on the outer wall of the shell, the liquid brushing rings are connected with liquid injection mechanisms, and the liquid brushing rings are connected with a pushing mechanism through connecting rods. By arranging the heat dissipation mechanisms on both sides of the rotor and connecting the heat dissipation mechanisms with the liquid delivery part, when the motor operates, the liquid delivery part can automatically extract the cooling liquid in the cooling cavity and input the cooling liquid into the heat dissipation mechanism, the cooling liquid flows in the heat conduction pipes of the heat dissipation mechanism, can quickly absorb the heat transferred to the heat conduction disc by the rotor, and then carries the heat back into the cooling cavity, forming a circulating loop for heat dissipation of the rotor, effectively solving the problems that the heat of the rotor of the traditional reluctance motor is difficult to dissipate and is easy to accumulate.
