Problems solved by technology

[0007] However, the thickness of the ring-shaped fixing bracket in the prior art is less than the length of the radial sensor, and the probe end of the radial sensor protrudes from the round hole of the ring-shaped fixing bracket. In this way, it is easy to cause the magnetic suspension bearing in the process of debugging. Shaft damage sensor problem
[0008] Therefore, how to solve the problem that the rotating shaft is easy to damage the radial sensor has become an important technical problem to be solved by those skilled in the art

Abstract

The invention discloses a sensor fixation support which comprises a hollow portion. The sensor fixation support is provided with installation grooves communicated with the hollow portion and used for accommodating sensors; the sensors are fixedly arranged in the installation grooves; and the probe ends of the sensors are arranged inside the installation grooves respectively. With the above structure, the sensor fixation support provided in the invention can prevent a rotation shaft from bumping and damaging the sensors. The invention also provides a magnetic-suspension bearing device comprising the sensor fixation support.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201310127701.7 and the title of the invention "A Magnetic Suspension Bearing Device and Its Sensor Fixing Bracket" filed with the China Patent Office on April 12, 2013, the entire contents of which are hereby incorporated by reference In this application. technical field [0002] The invention relates to the technical field of magnetic suspension bearings, in particular to a magnetic suspension bearing device and a sensor fixing bracket thereof. Background technique [0003] Magnetic suspension bearing is a bearing device that uses magnetic force to suspend the rotor in the air so that there is no mechanical contact between the rotor and the stator. [0004] The magnetic suspension bearing device includes a rotor, a sensor, a controller and an actuator. The function of the sensor is: when the rotor is disturbed downward or upward, it will deviate from its reference posit...
