Embodiment Construction

[0009] Such as figure 1 Therefore, in a shielded pump motor stator bar-type winding end insulation structure, the windings from the outermost turn to the innermost turn are respectively defined as the first turn to the fourth turn winding, and the tightening block 1 wraps the insulating tape 7 and plugs it tightly at the second turn. The inner ring of the four-turn winding 2 swivel joint, the insulating cover 6 wraps the fourth turn winding 2, the insulating tape 10 fixes the insulating cover 6 and the tie block 1, and the insulating tape 10 completely covers the insulating cover 6; the adhesive tape 11 connects the insulating plate 7 Paste to the inner ring of the third winding 3 swivel, the channel insulation 8 is installed on the ridge of the third winding 3 swivel, the corner insulation 9 is installed on the two corners of the third winding 3 swivel; the insulating tape 10 completely covers the insulation plate 7, the insulating plate 7 is plugged between the fourth turn w...

Abstract

The invention relates to a shield pump motor stator strip type winding end insulation structure. The insulation structure used in inter-turn insulation is that each wing is wrapped in an insulation cover and an insulation plate, an insulation tape is outside and firmly ties the insulation covers, the insulation plates and a fastening block together, channel insulation is wrapped around the ridgesof turning joints of the windings, corner insulation is wrapped around the corners of the turning joints of the windings, and the insulation plates are adhered to the inside of the turning joints andfirmly tie the channel insulation, the corner insulation and the insulation plates. The shield pump motor stator strip type winding end insulation structure compresses the operation space of winding end wrapping insulation, shortens the overall length of the winding, improves the utilization rate of the shield pump motor winding cavity, simplifies the insulation wrapping process, improves the endinsulation efficiency, reduces the risk caused by a tedious manual wrapping insulation process, and improves the reliability of strip type winding end wrapping insulation.

Description

technical field [0001] The invention relates to an insulation structure at the end part of the stator bar winding of a canned pump motor. Background technique [0002] The canned pump motor has the characteristics of full sealing, high safety, compact structure, small footprint, and stable operation. Among them, the two characteristics of full sealing and compact structure determine the internal space of the canned pump motor, especially the space at the end of the stator winding is smaller than other motors. There are usually two forms of canned pump motor stator windings: coil winding and strip winding. Coil winding, as the name suggests, is a winding made of a single-turn winding with insulation, and its ends do not require external insulation. Strip winding is a strip-shaped semi-winding that solidifies multi-turn windings with insulation together. It requires 2 windings to be welded together at the ends to form a complete winding. The ends need to be welded after weld...
