Description

Technical Field

[0001] The utility model relates to the technical field of transformer wire removal, in particular to a wire removal device for a reluctance type rotary transformer. Background Art

[0002] Based on the principle of electromagnetic induction, magneto-positive resolvers utilize variations in air gap and reluctance to cause the induced voltage in the output winding to vary sinusoidally or cosine-dependent with the mechanical angle. This principle operates by varying the air gap length, thereby changing the reluctance. By designing a resolver rotor with a specially contoured design, the air gap permeability varies according to a sinusoidal and cosine function. This results in a resolver output voltage that, under high-frequency excitation, has a sinusoidal and cosine relationship with the rotor's position angle.

[0003] During the initial design phase of a resolver, substandard quality and accuracy may occur. To identify the cause of the resolver test piece problem, the resolver must be manually de-wired. This involves removing the enameled wire wrapped around the stator, counting the number of turns per stator winding turn to determine the cause of the resolver error, and then re-winding the stator to compare the resolver's accuracy with the modified winding method. Existing de-wireing methods often involve manual labor and are time-consuming. Removing the enameled wire from a resolver's stator can often take hours, significantly reducing troubleshooting efficiency. To address this issue, we have developed a de-wireing device for reluctance resolvers. Utility Model Content
