Abstract

The invention provides a rotary transformer, which is characterized in that signal lines and windings are both connected with binding posts so as to realize signal transmission between the signal lines and the windings and improve the reliability of signal transmission between the signal lines and the windings; a signal wire harness is fixedly connected with a protective cover, the impact force borne by the signal wire harness is transmitted to an insulating framework matched with the first protective cover through a first protective cover in the using process instead of being directly transmitted to a connecting point of the signal line and the binding post, the connecting strength of the connecting point is enhanced, and the mechanical vibration resistance of the connecting point of thesignal line and the binding post is improved; furthermore, the signal lines are fixedly connected with the protective cover in advance according to a certain sequence, so that connection errors occurred when the signal lines are connected with the binding posts are avoided, the connection sequence of the signal lines does not need to be further sorted during connection, the production efficiency is improved, and the production intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a rotary transformer. Background technique [0002] Resolver (referred to as "resolver") is a kind of position sensor because it can work under harsh environmental conditions: such as mechanical vibration, high speed, high angular acceleration and noiseless requirements, as well as flammable, explosive, high and low temperature (-40 ~ 155 ℃) and other conditions, and has the advantages of high precision, high reliability, simple and compact structure, and low cost. It is widely used in the position sensor of power motors to detect the angle and speed of the motor rotor. [0003] The resolver used in the power motor is usually a reluctance resolver, which shows that all signal lines are wound on the stator, and no winding is arranged on the rotor. Its structure is mainly composed of the rotor pressed by silicon steel sheet, the stator pressed by silicon steel sheet, the insulating...
