Abstract

The invention discloses an inclination detecting method and system for a motor rotor detection disc. The method and system are applied to a magnetic suspension bearing system and are used for detecting the inclination of the detection disc assembled on a rotating shaft of a motor in the system. Particularly, when the detection disc is driven by the rotating shaft to rotate, multiple displacement values between a probe and the detection disc are obtained by displacement detection equipment arranged opposite to the detection face of the detection disc easily, the maximum displacement value and the minimum displacement value are searched from the multiple displacement values, a displacement deviation value is obtained by calculating the maximum displacement value and the minimum displacement value, the vertical distances from detection points corresponding to the displacement deviation value and the maximum displacement value to the axis of the rotating shaft of the motor is calculated according to the trigonometric function correlation theorem, and finally the inclination of the detection disc is obtained. According to the method and system, manual detection is not conducted through an argometer, human factors do not exist in the detection method, and therefore the problem that detection errors are large in a manual detection mode are large can be solved.

Description

technical field [0001] The present application relates to the technical field of automatic control, and more particularly, to a method and system for detecting the inclination of a detection disc of a motor rotor. Background technique [0002] In the magnetic suspension bearing system, in order to conveniently and accurately detect the axial displacement of the motor rotor, it is generally necessary to temporarily assemble a detection disk perpendicular to the rotating shaft on the rotating shaft of the motor. perpendicular, such as figure 1 shown. However, due to the inevitable engineering errors in the assembly process, the detection surface cannot be strictly perpendicular to the rotating shaft, such as figure 2 shown, but as long as the inclination is within the allowable threshold range, the detection of the axial displacement of the rotor is not substantially affected. Therefore, the inclination pair must be inspected after the inspection disc is assembled to deter...
