Abstract

The invention relates to an automatic-winding-device-based rotary transformer winding method. According to the technical scheme of the method, an insulation treatment manner of electrostatic coating on an iron core is carried out for replacing the insulation treatment manner of padding 6050 polyimide films and pasting 3240 epoxy glass fiber end pieces on the conventional iron core; research and smooth clamping of the rotary transformer iron core are realized according to the difference of winding manners and slot fullness rates, the parameters of winding span and winding tension are adjusted, and an automatic winding program is set and programmed to finish winding automatically; winding parameters and programs are optimized according to the rotary transformer test data after winding to wind qualified products. By virtue of the automatic-winding-device-based rotary transformer winding method, the rotary transformer processing period is shortened; meanwhile, the machine winding stress is uniform; the consistency is good; the survival rate of the rotary transformer is increased.

Description

technical field [0001] The invention relates to a technology for winding a rotary transformer by using automatic winding equipment. Background technique [0002] As the measuring element of aviation inertial navigation system, the azimuth resolver has the characteristics of small inner diameter, small notch, thin wire diameter and high slot filling rate. It is difficult to realize automatic winding, and it has been at the level of manual winding for a long time. A complete set of rotary transformer windings is divided into four sets of coils: rough machine stator winding, rough machine rotor winding, fine machine stator winding and fine machine rotor winding. The winding wire diameter and number of turns of each coil are different. When winding by hand, the coils are first wound on different winding molds, and then inserted into the slots of the stator and rotor cores respectively. This production process is not only time-consuming, but also prone to errors, resulting in lo...
