Reason for misalignment of brushless motor shaft
The operation mode of brushless motors is self-control, using semiconductor switching devices to achieve electronic commutation, that is, replacing traditional contact commutators and brushes with electronic switching devices. What is the reason for the misalignment of this motor shaft? Here is the editor's summary:
When the brushless motor is installed at a certain angle with the driven equipment, there will be an angle deviation. If the middle of the driven equipment and motor shaft are to be extended, they actually intersect with each other, rather than running or overlapping along the standard centerline. Compared to the slope of a fixed machine shaft, spatial or slope differences between the coupling surfaces of the motor shaft may occur in the vertical, horizontal, or both directions. Especially, misalignment of angles can cause serious damage to the driven instruments and motors
一旦两个轴的中线处于平行配置但不在同一条线上，就会发生平行失准。平行失准有两种形式，因为轴可能垂直移动，水平向左或向右移动，或者两者都有。一旦无刷电机轴的平行失准和角度失准同时发生，就会出现组合失准。Once the centerlines of two axes are in a parallel configuration but not on the same line, parallel misalignment will occur. There are two forms of parallel misalignment, as the axis may move vertically, horizontally to the left or right, or both. Once the parallel misalignment and angular misalignment of the brushless motor shaft occur simultaneously, a combination misalignment will occur.
Here, some suggestions and measures are proposed for the wellbore inclination problem of brushless motors. Firstly, the wellbore inclination of all key production instruments will be inspected once a year after 3 to 6 months of use to check whether the newly installed instruments will change due to foundation settlement. Remember, controlling vibration and increasing vibration trend are the main signs of misalignment. Misalignment may be due to insufficient bolt tightening, foundation settlement, or output shaft failure prediction maintenance methods, including spectrum analysis and vibration testing, used to distinguish shaft misalignment, bearing wear, or vibration caused by electricity.
The brushless motor is equipped with a photoelectric sensor device at a certain position on the stator component, a light shielding plate is installed on the rotor, and the light source is a light-emitting tube or a small light bulb. I hope the above content is helpful to you.
