DETECTION METHOD AND APPARATUS FOR MAGNETIC LEVITATION SYSTEM, STORAGE MEDIUM, AND PROCESSOR

摘要

A detection method and apparatus for a magnetic levitation system, a storage medium, processor, and a magnetic levitation compressor. The magnetic levitation system comprises a spindle (10), a motor (20), an electromagnetic bearing (30), and an auxiliary bearing (40). The motor (20) works to drive the spindle (10) to rotate. The electromagnetic bearing (30) and the auxiliary bearing (40) are separately disposed on the spindle (10), and the radius of the electromagnetic bearing (30) is greater than that of the auxiliary bearing (40). The detection method comprises: detecting whether the electromagnetic bearing stops working (S101); if it is detected that the electromagnetic bearing stops working, controlling the spindle to rotate at a predetermined rotational speed (S102); detecting working current of the motor (S103); and determining the state of the auxiliary bearing according to the working current (S104). Because the blocking or jamming of the auxiliary bearing (40) results in the increase of the working current of the motor (20), the state of the auxiliary bearing (40) can be determined according to the magnitude of the working current of the motor (20), and therefore, the state detection efficiency of the auxiliary bearing (40) is improved, real-time state detection of the auxiliary bearing (40) is realized, and accurate maintenance is achieved.
