Abstract
The utility model discloses a motor exciting coil with high insulating strength. The motor exciting coil comprises an exciting coil and is characterized in that the outer side of the exciting coil is coated with a silicon rubber insulating layer which is formed into one piece by hot pressing sulfuration. Due to the adoption of the structure, the outer side of the exciting coil of the utility model is closely coated with the silicon rubber insulating layer, and no space or gap occurs, so that the motor exciting coil has the advantages of improving insulating effect, enhancing insulating strength, thoroughly solving the problem of poor moisture proof capability, along with oil resistance, dust resistance, unnecessary drying and water washing, etc.
Description
One, technical field
The utility model belongs to technical field of motors, is specifically related to a kind of high insulation resistance motor excitation coil.
Two, background technology
Magnet exciting coil is the vitals of motor, and it is to be made of copper conductor, interlayer insulating film and turn-to-turn insulation layer.In order to prevent to occur the electric leakage sparking between magnet exciting coil and the rotor, cause the damage of magnet exciting coil, must be at magnet exciting coil outer wrapping insulating barrier.At present, the insulating barrier in the magnet exciting coil outside is to form in the following way: after mica tape or melamine alky varnished glass tape are twined in the magnet exciting coil outside, put it into dipping lacquer in the insulating varnish, after the taking-up drying, again at skin spraying protective paint.Because this insulating barrier is to be twined by several layers mica tape or melamine alky varnished glass tape to constitute, sky or slit between being prone in the insulating barrier make insulation effect be a greater impact, and have reduced dielectric strength.Especially the moisture proof ability is lower, and water or moisture are easy to enter magnet exciting coil inside in the slit from insulating barrier, makes the magnet exciting coil internal insulating layer puncture, and causes the magnet exciting coil scaling loss.
Three, summary of the invention
The purpose of this utility model provides a kind of reasonable in design, simple in structure, dielectric strength height, waterproof, the motor excitation coil that moistureproof ability is strong.
For achieving the above object, the technical solution adopted in the utility model is: comprise magnet exciting coil, be characterized in: be enclosed with the one-time formed silicone rubber insulation layer of hot-press vulcanization in the outside of magnet exciting coil.
Adopt said structure, the utility model magnet exciting coil is by the airtight parcel of one-time formed silicone rubber insulation layer in the outside, and insulation effect has been improved in sky or slit between can not occurring, and has increased dielectric strength, has thoroughly solved the problem of moisture proof ability.But also have grease proofing, prevent dust, exempt from drying, advantage such as can wash.
Four, description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of the utility model magnet exciting coil.
Five, embodiment
Shown in the figure of institute, the utility model---a kind of high insulation resistance motor excitation coil, it comprises magnet exciting coil 2, magnet exciting coil 2 is made of some copper conductors 6, turn-to-turn insulation layer 5, interlayer insulating film 7 and outer insulation 4.The purpose of each insulating barrier is in order to prevent short circuit sparking between the copper conductor, to cause the damage of copper conductor.Be enclosed with the one-time formed silicone rubber insulation layer 1 of hot-press vulcanization in the outside of magnet exciting coil 2.This hot-press vulcanization forming process is carried out in mould, and the sulfidization molding temperature is 165 ℃～175 ℃, and the time is 60～70 minutes.In order to make each insulating barrier on the magnet exciting coil, the soft extrusion coating paper of 6650 polyester-imide film aromatic polyamide fibres that temperature in the time of can bearing outer silicon rubber hot-press vulcanization moulding, turn-to-turn insulation layer and interlayer insulating film adopt heat resisting temperature can reach 180 ℃ respectively has 3253 polyamine-acid imide lamination glass-cloth board.In order to ensure the air emptying between the coil inside slit, and make coil integral body obtain solidifying the intensity that reaches higher, operating pressure in the time of can bearing the moulding of silicon rubber hot-press vulcanization, magnet exciting coil adopts the D006 Modified Polyimide Impregnating Varnish to carry out the vacuum paint dipping drying twice before the moulding of silicon rubber hot-press vulcanization.The terminal that among the figure 3 joins for magnet exciting coil 2 and power supply.
