Multi-shaft Motor Drive Separate Control Power Substrates

The substrate is divided into multiple isolation regions (first isolation region and second isolation region) that physically separate the power lines and signal lines. This segmentation allows both high voltage power lines and low voltage signal lines to coexist on the same substrate without interference, resolving the contradiction between integration and insulation by creating distinct functional zones on the substrate.

Different regions of the substrate are designed with different connection characteristics. The first isolation region accommodates amplifier modules with detachable connections for adaptability, while the second isolation region provides stable reference voltage supply. This local differentiation allows the system to achieve both detachability for configurability and stability for reference signals, resolving the contradiction between adaptability and connection reliability.

The patent merges the control substrate and power substrate into a single integrated substrate with isolated regions. This consolidation maintains the insulation benefits of separate substrates while reducing the overall device footprint. The first and second isolation regions are arranged in the same plane, eliminating the need for stacked layers or separate physical substrates, thus resolving the contradiction between insulation distance and device size.
