Single Speed Direct Drive Electric Drivetrain Space Optimization

The patent replaces the mechanical multispeed transmission system with an electric motor controller system that uses electronic control to achieve multiple speed ratios. The motor controller adjusts motor parameters (such as winding connections, pole pairs, or switching patterns) to provide different effective gear ratios, eliminating the need for physical transmission gears and reducing space claim while maintaining run out speed performance.

The patent changes the operational parameters of the electric motor through power electronic control to achieve variable speed ratios. By modifying electrical parameters (voltage, current, frequency, switching patterns) rather than mechanical parameters (gear ratios), the system achieves multiple speed levels without requiring a physically large multispeed transmission, thus resolving the contradiction between speed performance and space occupation.

The patent designs the electric drivetrain system with universal interfaces and modular architecture that can adapt to different machine applications. The electric motor and controller system serves multiple functions (propulsion, energy recovery, speed control) and can be configured for various power requirements, making the system versatile across different machine types while maintaining excellent electrical energy conversion capability.

The patent implements a dynamic control system that can adapt operating parameters in real-time based on load conditions, speed requirements, and energy availability. The motor controller dynamically adjusts electrical parameters to optimize performance across different operating scenarios, providing both excellent energy conversion and adaptability to varying machine requirements.

The patent replaces the complex mechanical multispeed transmission system with an electronically controlled motor system. Instead of multiple physical transmissions with associated mechanical linkages, the system uses power electronic controllers to achieve speed variation, significantly reducing device complexity while maintaining or improving speed control capability through electronic regulation.

The patent achieves multiple speed ratios by changing electrical parameters (such as inverter switching patterns, motor winding configurations, or controller algorithms) rather than mechanical parameters. This parameter-based approach simplifies the physical structure by eliminating complex mechanical transmission components while providing flexible and precise speed control through electronic parameter adjustment.
