Abstract

The invention relates to a position sensor aging test system and method for magnetic levitation equipment, and the system comprises a constant temperature box, a resistance tester, a controller, and alarm equipment. The constant temperature box is used for placing a to-be-tested position sensor; the constant temperature box is provided with a test port and a test line penetrating through the testport, and the to-be-tested position sensor is connected with the first end of the test line; the resistance tester is connected with the second end of the test line; the controller is respectively connected with the constant temperature box, the resistance tester and the alarm equipment; and the controller receives the resistance test data transmitted by the resistance tester within the heating time, processes the resistance test data, and triggers the alarm device to give an alarm when the resistance test data exceeds a resistance threshold range. The aging test of the position sensor is realized, the unqualified position sensor is checked, the fault of the magnetic suspension equipment caused by the direct installation of the unqualified position sensor on the magnetic suspension equipment is prevented, and the use stability of the position sensor is improved.

Description

technical field [0001] The present application relates to the technical field of aging testing, in particular to a position sensor aging testing system and method for magnetic levitation equipment. Background technique [0002] In the magnetic levitation equipment, it usually includes the motor stator, the motor shaft, the magnetic levitation bearing and the position sensor. Magnetic suspension bearings use magnetic force to suspend the motor shaft in the air, so that there is no mechanical contact between the motor shaft and the motor stator. The position sensor in the magnetic suspension bearing is used to sense the position of the motor shaft in real time, so that the rotor is always in a suspended state. The use stability of the position sensor affects the service life of the magnetic levitation equipment. [0003] The accuracy of the aging test results of the position sensor used in the current magnetic levitation equipment is low, and the stability of the position se...
