Description
Technical field
The present invention relates to motor impregnation field, specifically a kind of high temperature fixing glue of stepper motor coil.
Background technology
Stepper motor is the opened loop control unit stepper motor part that electric impulse signal is changed into angular displacement or displacement of the lines.In the case of non-overload, the rotating speed of motor, the position of stopping are solely dependent upon frequency and the umber of pulse of pulse signal, and do not changed by load and affected, when step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by the direction set, being referred to as " step angle ", its rotation is to run step by step with fixing angle.Pilot angle displacement can be carried out by controlling pulse number, thus reach the purpose being accurately positioned；Speed and the acceleration of electric machine rotation can be controlled simultaneously by controlling pulse frequency, thus reach the purpose of speed governing.
Stepping motor structure is simple, being widely used, be also used widely at aerospace field, this environment is the highest to stepper motor stability requirement, the existing glue being applied to coil fixing also exists non-refractory, the most low temperature resistant, it is impossible to the shortcoming used in a vacuum, after using this glue a period of time, glue intensity reduces, even completely destroying, coil will produce short circuit, and so may result in motor cannot work.
Summary of the invention
It is an object of the invention to provide a kind of high temperature fixing glue of stepper motor coil, this glue has applied range, resistance to thermal extremes, advantage that stability is strong.
For realizing the purpose of the present invention, the present invention uses below scheme:
A kind of high temperature fixing glue of stepper motor coil, it is characterised in that: including A, B two component, described component A includes following components: pottery, E-51 epoxy resin, maleimide, asbestos fibre, ethanol；Described B component includes following components: aromatic amine, molybdenum bisuphide.
Preferably, the described high temperature fixing glue of stepper motor coil, including A, B two component, described component A according to the mass fraction, including following components: pottery 5-10 part, E-51 epoxy resin 25-40 part, maleimide 20-35 part, asbestos fibre 1-3 part, ethanol 35-55 part；Described B component according to the mass fraction, including following components: aromatic amine 75-85 part, molybdenum bisuphide 15-26 part.
Preferably, the granularity of described pottery is not less than 400 mesh.
Preferably, described pottery is zirconia ceramics.
Preferably, the granularity of described asbestos fibre is 300-500 mesh.
Preferably, described aromatic amine be dimethylaniline, para-totuidine, 2, in 4-dimethylaniline one or more.
Preferably, the granularity of described molybdenum bisuphide is 300-500 mesh.
Preferably, described A, the mass ratio of B component are 1-3:1-2.
The present invention also provides for fixing by the using method of glue about described high temperature stepper motor coil, A, B component are mixed by ratio, spread upon coil one end, stand 15-25min, then smearing the glue of equivalent at the other end and stand 15-25min, the motor that will be equipped with coil puts into incubator, temperature 75-90 DEG C, insulation 3.5-5.5h, insulation the most persistently rotates.
The internal temperature of stepper motor can reach 200-280 DEG C, traditional general motor internal temperature is probably at 130 DEG C, therefore, traditional glue is used to be applied to the stepper motor coil of specific area, arise that glue is heated hot melt, cause coil to produce fine motion, make motor internal magnetic field size and Orientation change, have impact on the precision of stepper motor.Or carbonization, and then coil is caused to produce damage so that motor is short-circuited and cannot work.
The present invention specific employing E-51 epoxy resin, its epoxide number is at 0.48-0.54, there is good low temperature flow, immersing glue process easily flows into coil dead angle, it is aided with Maleimide-modified epoxy resin again, improve its high-temperature stability, under hot conditions, keep the characteristic of excellent adhesive and not hot melt.
Ceramic powders it is added with in component A, high temperature resistant and insulation characterisitic can be improved further, in particular by zirconia ceramics powder, it is aided with in granularity of the present invention, can be well into epoxy inner space and be attached on its space structure, rather than it is attached to its surface, so can give full play of the characteristic that zirconia ceramics powder is high temperature resistant and insulate.
Aromatic amine and the combination of molybdenum bisuphide is used in B component, molybdenum bisuphide Control granularity is 300-500 mesh, and aromatic amine uses an amine substance, both are together with each other, fill the interior spatial structure of full aromatic amine, make it have the most excellent lubricity, reduce the magnetic influence between coil, and then improve stepper motor precision.
The method have the benefit that
The ceramic powders using 400 mesh and above granularity in component A can be sufficient filling with in epoxy resin, optimizing each component number makes its each composition form homogeneous phase in ethanol, and then improve subsequent product quality, B component has minimizing internal friction, oxidation resistant characteristic, being equipped with certain proportion B component makes it solidify, and not only has good mobility, also enhances thermal conductivity.Ensure that coil dead angle is filled with glue, use AB combined simultaneously, use ratio can be adjusted according to concrete needs, thus obtain different glue property.The present invention each component Synergistic makes described glue have the most excellent heat resistanceheat resistant dilatancy and high temperature resistant, and internal friction is little, the most easy to crack, the feature that insulating properties is strong.In AB component, E-51 epoxy resin and aromatic amine other component of internal filling, improve the intrinsic frequency of glue, therefore, glue of the present invention is used to have the most excellent damping effect, coordinate the internal excellent lubricity of glue, so that motor can be with long time continuous working, it is ensured that stability.The present invention uses zirconia ceramics and molybdenum bisuphide, it is close with the relative density of molybdenum bisuphide that the former is mainly composed of zirconium dioxide, after AB component mixes, both influence each other little, in the reacted active ingredient of E-51 epoxy resin and aromatic amine, position is stable, being evenly distributed, both fit tightly together.
