Electric Motor Conversion System Footprint Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The configuration of electric motors and power distribution units differs from internal combustion engines, making direct replacement of internal combustion engines with electric motor and power distribution units challenging, as it alters the operational footprint of power equipment.
Innovation Solution
An electric motor conversion system that includes an electric motor, a power distribution unit, and a connecting bracket, where the electric motor is mounted on the work machine frame, and the power distribution unit is positioned atop the electric motor, with a connecting bracket between them, ensuring the system conforms to the footprint of the internal combustion engine, allowing for seamless replacement without impacting other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric motor and power distribution unit are configured separately, then control functionality is improved, but operational footprint compatibility deteriorates
Solution Approach 1:
The power distribution unit is positioned atop the electric motor, with the connecting bracket base covering the motor and extending upward to support the control unit. This nested arrangement allows the control functionality to be achieved while maintaining a compact footprint that conforms to the original internal combustion engine space.
Solution Approach 2:
Instead of expanding the footprint horizontally, the power distribution unit is positioned vertically atop the electric motor. This dimensional transition from horizontal to vertical arrangement maintains footprint compatibility while providing separate control functionality.
2Device complexity
If connecting bracket integrates motor and power distribution unit, then structural complexity is reduced, but manufacturing difficulty increases
Solution Approach 1:
The connecting bracket is designed as a separate component with a base that covers the electric motor and attachment elements extending from it. This segmentation allows the bracket to be manufactured independently and then assembled to connect the motor and power distribution unit, reducing overall manufacturing difficulty while maintaining structural simplicity.
Solution Approach 2:
The connecting bracket serves as an intermediary component between the electric motor and power distribution unit. This mediator approach allows both components to be manufactured separately using standard processes, then connected through the bracket, balancing structural integration with manufacturing ease.

AI summary
An internal combustion engine to electric motor conversion system for a work machine is provided. The electric motor conversion system is sized to substantially conform to a footprint of the internal combustion engine on the work machine. The electric motor conversion system includes an electric motor, a power distribution unit and a connecting bracket. The electric motor is configured for direct mounting on a frame of the work machine. The power distribution unit is separate from and positioned atop the electric motor. The power distribution unit controls operation of the electric motor. The connecting bracket is separate from the electric motor and power distribution unit. The connecting bracket includes a base, first attachment elements extending from a lower surface of the base for attachment to the electric motor, and second attachment elements extending from an upper surface of the base for attachment to the power distribution unit.
