Rotating Three-Phase to Two-Phase Transformer Design

The patent combines three-phase and two-phase transformer functions into a single integrated rotating transformer structure. The primary winding (three-phase) and secondary winding (two-phase) are housed together in one transformer body with a shared magnetic core, eliminating the need for separate fixed and rotating transformer units. This merging reduces overall mass and volume while maintaining full energy transfer capability.

The patent employs a rotating transformer design where the secondary winding is mechanically rotated relative to the primary winding. This dynamic rotation allows the transformer to avoid the static magnetic saturation and residual magnetization problems that plague fixed transformers. The continuous motion prevents magnetic flux from becoming trapped, eliminating residual magnetization effects and reducing current inrush during operation.

The patent integrates three-phase primary windings and two-phase secondary windings into a single transformer core structure. The magnetic core contains all necessary magnetic paths and the windings are arranged to achieve the three-to-two phase conversion directly within one device. This eliminates the need for multiple separate single-phase transformers and complex Leblanc connection arrangements, significantly simplifying the overall device structure.
