The invention provides an electromagnetic fault diagnosis device based on three-way magnetic sensors and a system and method thereof, and the device comprises an electromagnetic measurement array composed of a plurality of three-way magnetic sensors, a connection cable, a data collection transmitter, a data receiving comparator and a historical electromagnetic information library. The method comprises the following steps: recording values in X, Y and Z directions corresponding to an electromagnetic field vector signal generated when a product works under a correct working condition, generating a whole-course curve, taking the whole-course curve as a judgment basis, measuring the vector signal of a plurality of batches of same products in the same state at the same position at the same angle, analyzing the curve difference of the same type of products in different time domains, and judging whether the product works or not. And electromagnetic fault diagnosis is realized. The fault diagnosis method used in the
