Embodiment Construction

[0016] The process flow of the present invention is shown as the figure. Large-size coreless motor coil forming process, which includes the following steps: (1) Use hot-melt white sticky enameled wire to wind a polygon on a hexagonal or parallelogram wire mold, and stick tape on its straight side and then heat it. (3) Wind the flattened coil into a circle, wrap it with tape to shape it, and then adjust the circle under heating conditions to melt the enamelled layer of the hot-melt line again and form a whole; (3) The lead wire is tinned , stick the balance ring, and brush the epoxy resin glue to dry.

[0017] In order to more clearly illustrate the characteristics in the process flow of the present invention, so the problems existing in the existing traditional process are explained:

[0018] (1) Question 1: Loose coil problem

[0019] If ordinary enameled wire is used for winding (process 2), there is no doubt that the wire will loosen after removal. After testing, the adh...

Abstract

The invention relates to a coil molding process of a large-size coreless cup motor. In the coil molding process, (1) a hot-melting white-adhesion enamelled wire is wound into a polygon on a hexagonal or parallelogram line mode, and then the polygon is flattened under the heating condition after an adhesive tape is pasted on the straight line of the polygon; (2) the flattened coil is wound into a round coil, the round coil is corrected under the heating condition after being wound by the adhesive tape for formation, so as to lead the hot-melting wire enameled layer to be melted again to be pasted into an integrity; and (3) hot dip coating tin is carried out by a lead wire, a balance ring is pasted, and epoxy resin glue is brushed and dried. In coil molding process provided by the invention, the molding process of a coreless cup is solved, the existing difficulties and problems are solved as well as testing and recording are carried out according to the technical conditions of the coreless cup motor; and the motor meets the design requirements by data analysis.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to the manufacture of motor coils. It is especially involved in the manufacture of hollow cup motors in aviation, aerospace, weapons, medical equipment, robots, video cameras, cameras and some special fields, and even in the technical fields of textile machinery and laser measuring instruments. Background technique [0002] The coreless motor breaks through the rotor structure of the traditional motor in structure, and uses an ironless rotor, also called a coreless rotor. This novel rotor structure completely eliminates the power loss caused by the eddy current formed by the iron core, and its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor itself. Due to the structural change of the rotor, the operating characteristics of the motor have been greatly improved. It not only has outstanding energy-saving characteri...
