Abstract
In aspects, the present invention discloses a method of detecting a condition of an electric machine using a portable diagnostic device comprising one or more sensors for measuring at least one physical parameter associated with the electric machine in at least two axes. The method comprises measuring the at least one physical parameter associated with electric machine at a first position in a first axis and a second axis, determining a ratio of a first measurement of the at least one physical parameter in the first axis and a second measurement of the at least one physical parameter in the second axis at the first position, identifying a spatial distribution associated with the condition of the electric machine from a database based on the determined ratio and identifying the condition of the electric machine based on the identified spatial distribution.
