Description
Technical field
The present invention relates to a kind of production method of synchronous motor coil, particularly a kind of production method that adopts the synchronous motor coil that aluminium matter winding makes.
Background technology
Coil is as the core component of synchronous machine, its performance is self-evident to the influence of motor, and the general employing of the coil windings of prior art is copper, and the material of lead-out wire and winding is identical, this has caused cost height and weight big, greatly influences motor properties in some light-duty motors.The production process of the Chinese patent motor coil (patent No.: 86108071), it discloses a kind of concerning the stator coil that is flooded by full submergence, because the different thermal expansion of conductive material and insulating material can cause that the gap between main insulation and slot groove edge can utilize the dipping and the curing process program of carrying out continuously several times to be avoided.Every further curing is to carry out on lower temperature grade, and its temperature that begins approaches the class temperature of insulation assembly.Curing is to carry out under the situation of the stator axis that keeps flat, and will turn over 90 ° to stator before whenever entering subsequent processing.The mass of coil of above-mentioned scheme gained is big, is not suitable for micro-machine.
Summary of the invention
The invention provides a kind of employing aluminium and make coil, special soldering process, solved problems such as existing in prior technology weight is big, cost height.
Above-mentioned technical purpose of the present invention solves by the following technical programs:
A kind of production method of aluminum coil, it may further comprise the steps:
A, aluminium enamel-covered wire is wrapped on the coil rack, aluminium enamel-covered wire is fixed with insulating tape;
B, the part that divests that A is gone on foot two the end of a thread of coil of gained and lead-out wire are twined more than 5 circles;
C, weld after the winding of B portion gained coil and lead-out wire partly flooded aluminum brazing flux;
D, with the soldered winding part impregnated with paint.
Usually, the coil that the winding of employing aluminium matter is made and the contact resistance in conjunction with producing of lead-out wire are bigger, bigger to the motor properties influence, simultaneously because the winding of copper lead-out wire and aluminium matter welding difficulty, cause both loosening, disengaging easily, when the present invention has adopted aluminium matter coil windings the winding of aluminium matter winding and copper lead-out wire is partly twined more than 5 circles, and will weld behind its dipping aluminum brazing flux again, this welding method has solved the contact resistance height, has connected not firm problem.
As preferably, described paint is from the dryness impregnating varnish.This paint is commercially available, can reach purpose of the present invention preferably.
In order to reach better welding effect, as preferably, the weight percent of the aluminum brazing flux of C in the step consists of ptfe aluminum potassium and potassium hexafluoroaluminate eutectic 92.0%～94.5%, cadmium fluoride 0.5%～3.0%, surplus are tin fluoride.Welding quality when the aluminum brazing flux of this compatibility can make copper plain conductor with aluminium matter contact preferably.
As preferably, the welding temperature of C in the step is 250～310 degrees centigrade.Because making, the combination of aluminum material and copper material temperature control requirement strictness of the present invention experimental results show that the gained motor coil fastness and the electric efficiency of welding are comparatively desirable under 250～310 degrees centigrade condition.
As preferably, it further comprises following steps: heat after the winding that D is gone on foot gained partly puts heat-shrinkable T bush.Do like this and can further improve fastness of the present invention, the oxidation that can slow down weld simultaneously.
Therefore, the present invention has characteristics such as sound construction, cost be low.
