Embodiment Construction

[0016] In the winding of the output side, the rough machine winding takes any slot as the starting position to wind the first component, and marks this slot as the first slot, write the slot number clockwise, and the rest of the windings are centered on the first slot in order Winding; such as figure 1 Expand as shown. The first component of the precision machine winding in the output side winding is wound starting from the 1+n slot, and the rest are wound sequentially. The sine and cosine wiring positions are the same; see figure 2 , image 3 shown.

[0017] In the actual design, n is related to the number of pole pairs p of the dual-channel resolver, the number of slots Z on the output side, and the core material.

[0018] n = I N T ( Δ α 2 × 360 / ...

Abstract

A wiring method for a roughing-fining machine winding space in a double-channel rotary transformer is characterized in that a reversed error value is formed in advance making use of the difference in a spatial arrangement of output windings, so that a difference of the zero positions of the roughing-fining machine caused by the dissymmetry of mechanical machining the inconformity between each winding element is offset, and the zero position of a roughing machine and that of a fining machine are kept overlapped as much as possible in practical application. According to the wiring method for the roughing-fining machine winding space in the double-channel rotary transformer, just by adopting the method of producing the reversed error value in advance, the problem that the difference of the zero positions of the roughing-fining machine exceeds a standard in the design process of the double-channel rotary transformer is perfectly resolved, the requirement on the machining precision of iron cores of a stator and a rotor is reduced greatly and percent of pass is improved.

Description

technical field [0001] The invention relates to the space arrangement of windings of an equal-angle signal sensor of a rotary transformer, in particular to the spatial wiring of the windings of a coarser and finer machine in a double-channel rotary transformer. Background technique [0002] The dual-channel resolver has the advantages of simple structure, high reliability, few parts, light weight, and good processing technology. Its performance indicators and The test accuracy is not affected, and it can be used in aviation, aerospace, weapons and other fields that have high requirements for environmental conditions. [0003] The structure of the dual-channel resolver is similar to that of the sine-cosine resolver and the two-phase winding asynchronous motor, consisting of a stator and a rotor. The electrical structure is composed of a coarse channel and a fine channel, which can output a signal that is strictly in the positive and cosine relationship with the rotor angle, ...
