Abstract: An apparatus and method for generating a motor diagnosis model. Each first dimension-reduced datum of a first motor corresponds to a normal state, an offline state, or an abnormal state, while each second dimension-reduced datum corresponds to the normal state or the offline state. The apparatus rotates the first dimension-reduced data or the second dimension-reduced data and integrates the rotated results with the dimension-reduced data that have not been rotated as a to-be-analyzed dataset. The apparatus trains a classification model for distinguishing data sources by using a subset of the to-be-analyzed dataset, derives an accuracy rate by testing the classification model for distinguishing data sources by using another subset of the to-be-analyzed dataset, and determines whether to use the to-be-analyzed dataset to generate the motor diagnosis model for the second motor.
