Abstract

The present disclosure relates to methods and systems for detecting the state of a motor. In some aspects, the present invention discloses a method of detecting a condition of an electric motor using a portable diagnostic device including one or more sensors for measuring at least one physical parameter associated with the electric motor in at least two axes. The method includes measuring at least one physical parameter associated with the motor at a first location in a first axis and a second axis, determining the first measurement of the at least one physical parameter in the first axis and the second axis in the first location A ratio of the second measurement of the at least one physical parameter, identifying a spatial distribution associated with a state of the electric machine from the database based on the determined ratio, and identifying a state of the electric machine based on the identified spatial distribution.

Description

technical field [0001] The present invention relates to the field of condition monitoring of electric machines, and more particularly, the present invention relates to the detection and determination of faults in electric machines using the spatial distribution of one or more physical parameters associated with the electric machine. Background technique [0002] Health monitoring of an electrical machine, such as an electric motor, and subsequent diagnosis of faults in the electrical machine can be accomplished using a variety of techniques known in the art. In one such technique, a visual representation of one or more parameters, such as temperature, magnetic field, etc., of the volume surrounding the motor is generated by collecting measurements of parameters surrounding the motor. For example, a three-dimensional heat map can be drawn in the space around the motor, which indicates the magnetic field strength around the motor. Based on the three-dimensional heat map, main...
