Abstract

A method, system and storage device are generally directed to determining for each of a plurality of data points, a neighborhood of data points about each such data point. For each such neighborhood of data points, a projection set of polynomials is generated based on candidate polynomials. The projection set of polynomials evaluated on the neighborhood of data points is subtracted from the plurality of candidate polynomials evaluated on the neighborhood of data points to generate a subtraction matrix of evaluated resulting polynomials. The singular value decomposition of the subtraction matrix is then computed. The resulting polynomials are clustered into multiple clusters and then partitioned based on a threshold.

Description

technical field [0001] The present invention relates to stators of rotating electrical machines, such as electric motors, generators, etc., and in particular to terminal units comprising busbars connected to phase windings of the stator windings. Background technique [0002] In generators used in EVs (electric vehicles) and PEVs (pure electric vehicles), large currents are passed through the stator windings, so busbars with a large cross-sectional area are used. Therefore, the size of the terminal unit including the bus bars increases, and interference with peripheral parts of the motor occurs. Therefore, a technique for compactly housing the terminal unit near the motor is required. [0003] In view of the above situation, the busbars are arranged in two layers in the vertical direction and arranged in a zigzag or diagonal shape, and the insulating members are used to insulate and cover each busbar to form a wiring unit, thereby realizing the compactness of the wiring unit...
