Reshaping and processing method of wrapping and winding motor ring-type coil

Abstract

The invention relates to a reshaping and processing method of a wrapping and winding motor ring-type coil, belonging to the technical field of high-voltage motors. The reshaping and processing method comprises a preparation procedure, a winding procedure and a lead tin-immersion head-scraping procedure, and is characterized in that the winding procedure leads two leads to pass through a gathering device and a belting machine in parallel and controls carriage speed to wrap and wind mica tapes to a starting position of a winding former; and after the winding procedure, the procedure of wrapping protecting belts is carried out and wraps a wound shuttle coil with white cloth belts by a 1 / 2 half-lap winding-wrapping-winding manner. The method has the advantages of simple technique, convenient processing, stable electric performance, low cost, even and no-folding lap winding and flat attaching, accurate size, good product quality and high processing efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of high-voltage motors, and in particular relates to a method for shaping and processing coils of motor coils while wrapping around them. Background technique [0002] At present, the stator coil of the 10,500-volt class high-voltage motor is modified to increase the capacity of the unit. The slot shape of the existing stator has been determined. In order to achieve the purpose of capacity expansion and transformation, the design structure is to lengthen the stator core, the total length of the stator coil remains unchanged, and the straight line is lengthened and the end is shortened. Part, make full use of the slot full rate, use new insulating materials, thin the insulation, increase the cross section of copper wires, use 2 copper wires to wind parallel and side by side to make 11 turns, and use high-strength copper horse powder mica tape for inter-turn insulation wrapping Half-stacked wrapping, another l...

[0002] At present, the stator coil of the 10,500-volt class high-voltage motor is modified to increase the capacity of the unit. The slot shape of the existing stator has been determined. In order to achieve the purpose of capacity expansion and transformation, the design structure is to lengthen the stator core, the total length of the stator coil remains unchanged, and the straight line is lengthened and the end is shortened. Part, make full use of the slot full rate, use new insulating materials, thin the insulation, increase the cross section of copper wires, use 2 copper wires to wind parallel and side by side to make 11 turns, and use high-strength copper horse powder mica tape for inter-turn insulation wrapping Half-stacked wrapping, another layer of half-stacked wrapping, which brings great difficulty to the winding of the side-wrapped coil and the processing of the expansion process. When winding, it is easy to overlap the wires, and the measurement size of each turn is not accurate, and it is easy to The height and size of the coil after inter-strand gelation is out of tolerance, resulting in the number of insulation wrapping layers not being included, affecting the electrical insulation strength, high breakdown rate between turns, causing a lot of waste of raw materials, affecting product quality and production efficiency
