Abstract
The utility model discloses a metal coil which comprises a plurality of coil bodies which are formed by winding conducting wires and have hollow structures. The coil bodies are connected by bridge lines. Outer surfaces of the coil bodies are coated with plastic powder layers. According to the metal coil of the utility model, problems of a complicated working procedure of bundling insulated cloth belts, low speed of dipping paint and drying and the like of a traditional motor coil are solved.
Description
Technical field
The utility model belongs to the motor device field, is specifically related to be wrapped in a kind of wire coil in the motor.
Background technology
Wire coil all is equipped with in motor stator casing the inside under the regular situation, wire coil is to be entwined by copper cash, be lined with fish paper and white shell paper between the copper cash, connect with intercoil connection between the coil, have sleeve pipe and brush on the intercoil connection, the coil outer surface is fixed coil with insulating cloth tape, and coating insulating varnish, by outer field insulating cloth tape with insulating varnish plays and casing, the effect of rotor insulation, and then be installed in the motor stator, on technique, tie up the insulating cloth tape operation numerous and diverse, not only will expend a large amount of labours, and the used insulating varnish of paint-dipping process is the alkyd amino impregnating varnish, this lacquer rate of drying is slow, paints the highly seasoned environmental protection that is unfavorable for.
The utility model content
To tie up the insulating cloth tape operation numerous and diverse in order to solve the conventional motors coil for the utility model, and the dipping lacquer rate of drying waits problem slowly, has designed a kind of wire coil.
The utility model is achieved through the following technical solutions and solves the problems of the technologies described above: a kind of wire coil, described wire coil comprises a plurality of coil cases with hollow-core construction that are entwined by plain conductor, connect with intercoil connection between the coil case, the coil case outer surface is coated with the molding powder layer.Its advantage is: compared with prior art, adopt the molding powder layer to replace traditional insulating cloth tape and insulating varnish, the link that has reduced dipping lacquer and twined insulating cloth tape, not only easier on technique, labor savings, and molding powder layer insulation property are better, failure rate is low, rate of drying is fast, aspect production environment than more environmental protection of insulating varnish.
Described wire coil, wire are flat type copper wire.Its advantage is: coil method generally can adopt the materials such as copper, aluminium, silver, and flat type copper wire is compared with other wire rod, under equal volume, have lightweight, resistance is low, efficient is high, the characteristics that noise is little.
Described wire coil is lined with insulating board between the flat type copper wire of formation coil case.Its advantage is: insulating board can play and prevent from occurring between the flat type copper wire short trouble, and insulating board forms through certain technique manufacturing generally by wood fibre or mix the mixed pulp of cotton fiber, has good mechanical strength, higher electrical strength, and surfacing is smooth, is rich in toughness.Coil case is to put insulating board by flat type copper wire phase alternating floor to be entwined at special equipment, also is lined with insulating board between coil case top and flat copper coil.
Described wire coil, there is the tying strap in the terminal system of coil case.Its advantage is: play the effect of static line circle body, prevent the loose distortion of coil case.
Described wire coil, molding powder layer are the epoxy insulation powder.Its advantage is: the epoxy insulation powder has good adhesive force, chemical resistance, thermal endurance and excellent electrical insulating property.Mechanical property and environmental-protecting performance are good, are difficult for breaking in integer and the assembling process, and the surface that can cover by the mode of hot dip coating, thermal spraying, electrostatic coating workpiece reaches the insulation purpose.
Described wire coil, epoxy insulation powder bed thickness is the 0.5-0.8 millimeter.Its advantage is: both played the coil case insulating effect, do not affected again motor performance.
Described wire coil, cover has sleeve pipe on the intercoil connection.Its advantage is: sleeve pipe plays the insulating effect between intercoil connection and the coil case, dielectric strength between the enamelled wire of reinforcement different directions electric current.
Described wire coil is welded with brush on the intercoil connection.Its advantage is: brush is used for and phase changer cooperates the realization commutation, drives direct current machine and rotates.
