High-frequency rotary transformer armature and winding fixing method thereof

Abstract

The invention provides a high-frequency rotary transformer armature and a winding fixing method thereof. The high-frequency rotary transformer armature comprises windings and an iron core; a pluralityof iron core teeth are uniformly and fixedly connected to the annular inner wall of the iron core, tooth slots are formed between the adjacent iron core teeth, the windings are embedded into all thetooth slots correspondingly, and the windings are tightened by a binding wire and fixed in the iron core through the binding wire. Through the wiring mode of the binding wire, the windings at the twoends of the armature and the windings in all the iron core slots of the iron core can be fixed by only one wire; the binding wire is dragged on each fixing point, and the fixing effect is better; andwhen the binding wire is wound on the teeth of the iron core, the slot insulation is blocked behind the binding wire, so that the slot insulation is prevented from being higher than inner holes of theiron core, and meanwhile, varnished wires in the iron core slots are pressed by the slot insulation.

Description

technical field [0001] The invention relates to a high-frequency resolver armature and a winding fixing method thereof. Background technique [0002] As the sensing element of position and speed, the resolver requires high precision and reliability. In addition to the traditional military and aerospace fields that require high reliability, it has also been widely used in industry, transportation, and civilian fields in recent years. Usually, the diameter of the enameled wire used in the resolver is very small, some reach 0.1mm or even smaller, which is very easy to cause damage or breakage of the enameled wire during the armature processing process, so the processing technology is very difficult. In addition, for the resolver stator armature with distributed winding, it needs to cross several slots when it is off the line, and because the diameter of the enameled wire used is small, it can only be off the line manually, and the enameled wire at the end is relatively loose, ...

AI Technical Summary

Problems solved by technology

The purpose of driving in the slot wedge is to prevent the slot insulation from being higher than the inner hole of the iron core and interfere with the rest, and at the same time prevent the enameled wire from coming out of the slot and interfering with the rotor to cause the motor to sweep. The slot wedge may cause the notch to be deformed, and it is easy to cause damage to the iron core, which will affect its performance. Since the iron core is short, the slot wedge is easy to loosen and fall out, failing to achieve the purpose of fixing the coil
