KMO, short for Kaiser Meyer Olkin, is a test statistic used to compare the simple correlation coefficient and the partial correlation coefficient between variables.
< br >
The KMO statistic is between 0 and 1. When the sum of squares of the simple correlation coefficients among all variables is much larger than the sum of squares of the partial correlation coefficients, the KMO value is close to 1. The closer the KMO value is to 1, the stronger the correlation between variables is, and the original variables are more suitable for factor analysis. When the sum of squares of the simple correlation coefficients among all variables is close to 0, the KMO value is close to 0. The closer the KMO value is to 0, the weaker the correlation between variables, and the less suitable the original variables are for factor analysis.
In the electrical symbol, KM is generally used to represent the contactor coil, and if there are multiple coils in the circuit diagram, KM0 KM1 is generally used to distinguish in turn.
The KMO (Kaiser-Meyer-Olkin) test statistic is an index used to compare the simple correlation coefficient and the partial correlation coefficient between variables. The other is km refers to the electric contactor, and the coil is identified by km0 and km1.
KM in electrical diagrams, generally represents the AC contactor symbol.
AC contactor is mainly composed of four parts:
(1) electromagnetic system, including an attraction coil, a moving core and a static core; (2) The contact system comprises three groups of main contacts and one to two groups of normally open and normally closed auxiliary contacts, which are connected with the moving core and interlinked with each other;
(3) arc extinguishing device, generally large capacity AC contactors are equipped with arc extinguishing device, in order to quickly cut off the arc, avoid burning the main contact;
4) Insulation shell and accessories, all kinds of springs, transmission mechanisms, short-circuit rings, terminals, etc.
