Characteristic analysis and optimization of modified rotary transformer

The emergence of the rotary transformer has provided a new solution to replace the brushes of electric motors. This paper presents structural modifications based on traditional rotary transformers to study the transmission characteristics of electrical energy. It explores the impact of key parameters on performance through theoretical analysis, establishes a finite element model for validation, and conducts simulation analyses in both stationary and rotating states. To address the nonlinear changes occurring in the rotating state that may lead to suboptimal designs, a solution using genetic algorithms is employed, resulting in a comprehensive design scheme for rotary transformers.
