Abstract

The invention relates to an automatic testing method and device for a rotary transformer, and relates to the field of electromagnetic element manufacturing. The invention discloses the automatic testing method for the rotary transformer. The sine output zero voltage of a stator is efficiently and accurately found by controlling a rotor to rotate at a low speed and rotate positively and negativelyin a fine-tuning manner; a zero voltage interval range and a phase difference are used; the problem type is intuitively and effectively judged; fixed-angle stepping rotation of the rotor is controlled; a stator output voltage theoretical peak value data set is obtained through multiple times of fixed-angle stepping rotation, statistical analysis is conducted on the sine output voltage theoreticalpeak value data set and the cosine output voltage theoretical peak value data set respectively, a data dispersion coefficient serves as a peak value voltage consistency index, quantification of a problem judgment basis is achieved, and the test accuracy is improved.

Description

technical field [0001] The invention provides a rotary transformer automatic testing method and device, which relate to the field of electromagnetic element manufacturing. Background technique [0002] Resolver, referred to as resolver, is a micro-motor for control. It is a measuring device that uses the principle of electromagnetic induction to transform the mechanical rotation angle into an electrical signal that has a certain functional relationship with the rotation angle. Compared with optical encoders, Other position sensing elements such as magnetic encoders have better environmental suitability. The winding of the resolver is extremely complicated, and the stator (rotor) usually contains more than two sets of windings. There are differences in the number of turns of the coil, the position in the slot, and the polarity of the winding, which requires extremely high skill for the operator. The correctness of the winding has an important influence on the performance in...
