Abstract

The invention discloses a magnetic suspension motor for measuring an axial sensor bracket structure of a rotor. The magnetic suspension motor comprises the rotor, a support, a casing, an axial sensor bracket, pads, an axial sensor circuit board, an axial sensor and an axial compensation sensor, wherein the casing is connected with the support through a screw, the axial sensor bracket is fixed on the casing through a screw, the axial sensor circuit board is fixed on the axial sensor bracket through a screw, the axial sensor and the axial compensation sensor are both mounted in the axial sensor bracket and are correspondingly connected with the axial sensor circuit board, and the pads are arranged between the axial sensor bracket and the casing. The magnetic suspension motor is advantaged in that equipment mounting debugging can be realized through only changing the quantity of the pads to realize requirements for a gap between the preset rotor and the axial sensor bracket, and thereby normal operation of the sensors during operation of the rotor and measurement accuracy of a displacement value of a magnetic bearing are both guaranteed.

Description

[0001] Technical field: [0002] The invention relates to an axial sensor support structure of a magnetic levitation motor measuring rotor. [0003] Background technique: [0004] In the existing centrifugal fan, during the normal operation of the fan, the magnetic bearing changes the size of the energized current through the displacement information fed back by the axial displacement sensor, so as to control the normal suspension of the rotor. The axial displacement sensor of the existing fan is installed at the bottom of the rotor, and is connected with the machine base through cooperation, which is not convenient for installation and debugging. [0005] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. [0006] Invention content: [0007] The present invention provides an axial sensor support structure for measuring the rotor of a magnetic levitation motor in order to solve the above-mentioned problems in the prior art. [000...
