The invention discloses a detection coil, the detection coil includes: at least one U-shaped winding arranged at the bottom of the stator slot of the motor, wherein all the detection coils included in the detection coil are determined according to the detection requirements and the connection rules of the motor windings. The arrangement and connection method of at least one U-shaped winding are described. Therefore, the detection coil of the embodiment of the present invention can not only realize the optimization of the distribution position and number of turns of the U-shaped winding, but also realize the optimization of the pitch, number of turns and position of the detection coil, and can be realized through the combination of different U-shaped windings. Different detection requirements have the advantages of flexibility, convenience, and easy realization in technology.
Description
detection coil technical field [0001] The present invention relates to the technical field of motor fault detection, in particular to a detection coil. Background technique In the related art, the induced electromotive force of the magnetic flux of the stator teeth is detected by winding the detection coil on the stator teeth, so as to diagnose the Whether there is an inter-turn short-circuit fault in the motor; according to certain principles, a detection coil is arranged in the stator slot, and the Analyze the characteristic harmonics of the induced electromotive force of the detection coil to diagnose whether the motor has a short-circuit fault. However, there are problems with related technologies The problem is that it is impossible to optimize the detection coil pitch, number of turns, and position, and it is impossible to obtain rich information to achieve different detection methods. test needs. SUMMARY OF THE INVENTION [0003] The present invention aims ...
