Abstract

The invention discloses a detection coil, and the coil comprises at least one U-shaped winding arranged at the bottom of a motor stator slot, wherein the arrangement and connection mode of the at least one U-shaped winding included in the detection coil are determined according to the detection requirement and the connection rule of the motor winding. Therefore, the detection coil provided by theembodiment of the invention not only can realize the optimization of the distribution position and the number of turns of the U-shaped winding, but also can realize the optimization of the pitch, thenumber of turns and the position of the detection coil, can realize different detection requirements through the combination of different U-shaped windings, and has the advantages of flexibility, convenience and easiness in realization in process.

Description

technical field [0001] The invention relates to the technical field of motor fault detection, in particular to a detection coil. Background technique [0002] In the related technology, the induction electromotive force of the stator tooth magnetic flux is detected by winding the detection coil on the stator teeth to diagnose whether the inter-turn short circuit fault occurs in the motor; according to a certain principle, a detection coil is arranged in the stator slot, and the detection coil induction The characteristic harmonics of the electromotive force to diagnose whether the motor has a short-circuit fault. However, the problems in the related technologies are that it is impossible to optimize the pitch, number of turns and position of the detection coil, and it is impossible to obtain rich information to meet different detection requirements. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at l...
