Claim 5:
6. The magnetic bearing compressor of claim 5, wherein the control device is further configured to:
send a fifth electric signal to the second magnetic bearing while sending the third electric signal to the first magnetic bearing within the second preset duration;
send a sixth electric signal to the second magnetic bearing while sending the fourth electric signal to the first magnetic bearing;
control, by the fifth electric signal, the second magnetic bearing to attract the rotor in a third direction where the second sensor is located until the rotor is in contact with the second magnetic bearing;
control, by the sixth electric signal, the second magnetic bearing to attract the rotor in a direction opposite to the third direction until the rotor is in contact with the second magnetic bearing;
determine a second maximum distance value and a second minimum distance value between the rotor and the second sensor within the second preset duration;
obtain a second absolute value of a difference of the second maximum distance value and the second minimum distance value; and
determine a second protective air gap value of the second magnetic bearing according to the second absolute value;
wherein the third direction is opposite to the second direction.
