Description

technical field [0001] The invention relates to the technical field of motor manufacturing detection, in particular to a coil insulation layer detection device applied to motor coils. Background technique [0002] Motor coils include stator coils and rotor coils. Motor coils are prone to damage to the insulation layer after long-term use. After the insulation layer is damaged, the coil will generate heat and leak current when it is energized, which poses a great safety hazard. [0003] When the existing motor coil insulation layer detection device performs insulation detection on the stator coil or the rotor coil, because the diameters of the rotor coil and the stator coil are different, different coil fixing devices need to be replaced, and the fixing effect on the coil is poor, which is wasteful.

[0002] Motor coils include stator coils and rotor coils. Motor coils are prone to damage to the insulation layer after long-term use. After the insulation layer is damaged, the coil will generate heat and leak current when it is energized, which poses a great safety hazard.

[0003] When the existing motor coil insulation layer detection device performs insulation detection on the stator coil or the rotor coil, because the diameters of the rotor coil and the stator coil are different, different coil fixing devices need to be replaced, and the fixing effect on the coil is poor, which is wasteful. Time is not conducive to the insulation layer damage detection of the coil to be detected, and the existing motor coil insulation layer detection device judges the damage of the insulation layer according to the leakage current, the detection accuracy is low, and in the detection process, the detection coil cannot be detected. Marking the damaged position of the insulating layer is not conducive to the later repair of the coil to be detected, and reduces the detection effect of the detection device
