Propulsion Using Dc Motors TRIZ Cases
- Drive Unit Connector Sequencing for Hot-Swappable Replacement
Detachable power and control connectors let one drive unit be replaced without stopping the full system, while sequenced disconnection limits arcing and wear.
- Universal UAV Tether Power Supply With High-Voltage DC Feed
High-voltage DC over a tether cuts cable losses and heat, while a universal aerial supply adapts power to different small UAV classes.
- Roof-Mounted Main Transformer Layout for Double-Deck Rail Carriages
Placing the main transformer above the bogie frees passenger space, shortens power lines, and improves weight balance in double-deck rail carriages.
- Overhead Traveling Vehicle Wheel-Motor Layout for Lower Profile
By placing the drive motor on the traveling wheel axis and using track notches, this case cuts traveling section height without wall interference.
- Traction Converter Power Mode Detection for Safe AC/DC Switching
Automatic grid-voltage detection switches the traction converter between AC and DC modes to prevent manual errors and circuit damage.
