Abstract
The invention discloses a manufacture method of a waterproof motor coil, relating to the field of waterproof production technologies of motor products. In the current production process of motor products, in the waterproof technologies, the sealing of each component on an outer surface of the motor is considered, but sealing effects of the waterproof technologies are always not satisfied, and the waterproof technologies has short service life. According to the manufacture method of the waterproof motor coil disclosed by the invention, problems of bad sealing effects are solved by immersing the manufactured motor into paints for sealing, by means of the technological design, the manufacture method has an advantage of good sealing effects.
Description
Technical field
The present invention relates to motor coil product waterproof production technology field.
Background technology
Motor comprises stator and rotor, principle is that hot-wire coil rotates bar magnet, motor in wet environment often coil puncture and to go wrong, now in the motor product production process, waterproof technology is each parts of paying attention in the motor appearance, comprises that forward and backward end cap and shell are seamless structures, between the faying face of Wiring port and terminals, be provided with sealing mechanism between the faying face of fastening bolt and bolt hole, be provided with movable sealing mechanism between motor coil axle and the axis hole.The parts of motor outer surface adopt the anti-corrosion material manufacturing or have anticorrosive coat.Shortcomings such as these methods are exactly appearance sealing nothing more than, but sealing can not make us relieved all the time, and useful life is long the invention provides a kind of manufacture method of waterproof machine coil, solve the bad problem of present sealing effectiveness.
Summary of the invention
The present invention can not make us relieved all the time for solving motor seal, and the problem that useful life is long has proposed a kind of manufacture method of waterproof machine coil.
Technical scheme of the present invention is: a kind of manufacture method of waterproof machine coil, motor coil is put into vacuum tank, inject insulating varnish, after treating complete submergence motor coil, seal, at this moment, insulating varnish also has certain space between seal cover, space between insulating varnish and the seal cover is vacuumized, and vacuum meter pressure requires to reach 95Pa, and keeps 120 seconds, if vacuum degree and time are not enough, insulating varnish can not infiltrate motor coil inside fully, does not reach the effect of the inner each several part of sealing motor coil, and the viscosity of insulating varnish is 20 seconds, the insulating varnish temperature keeps 25 ℃ ± 2 ℃, then the motor coil behind the dipping lacquer is dried, bake out temperature is spent to 140 degree from 90 and is raise gradually, and oven dry total time is 100 minutes.
Technological design like this has advantage of good sealing effect.
Description of drawings:
Embodiment:
The production of the spare and accessory parts of motor and assembling are with common production method, repeat no more herein, what we needed is that motor coil is carried out vacuum paint dipping, motor coil is put into vacuum tank, inject insulating varnish, after treating complete submergence motor coil, seal, at this moment, insulating varnish also has certain space between seal cover, and the space between insulating varnish and the seal cover is vacuumized, vacuum meter pressure requires to reach 95Pa, and keep 120 seconds, if vacuum degree and time are not enough, insulating varnish can not infiltrate motor coil inside fully, do not reach the effect of the inner each several part of sealing motor coil, the viscosity of insulating varnish is 20 seconds, and the insulating varnish temperature keeps 25 ℃ ± 2 ℃, then the motor coil behind the dipping lacquer is dried, bake out temperature is spent to 140 degree from 90 and is raise gradually, oven dry is 100 minutes total time, and the motor coil of producing has like this been realized isolated fully with outside air, thereby improves the quality of products.
Claims (1)
