Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical generator systems face challenges in managing shear forces on rectifier assemblies due to high rotational speeds, leading to potential mechanical stress and instability.
Innovation Solution
The rectifier assemblies are arranged radially with respect to the rotational axis, featuring diodes stacked in a perpendicular configuration, and balanced by dummy assemblies to mitigate shear forces, allowing for higher rotational speeds and improved mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rectifier assemblies are arranged parallel to the rotational axis, then the electrical connection is simplified, but the shear forces on the rectifier assemblies increase due to high rotational speeds
Solution Approach 1:
The rectifier assemblies are reoriented from a parallel arrangement to a radial arrangement relative to the rotational axis. This dimensional change in orientation transforms the stress distribution, reducing shear forces while maintaining electrical connectivity through the radial configuration of diodes and terminals.
2Productivity
If the rotational speed is increased to improve productivity, then the power generation capacity increases, but the mechanical stress and instability on the rectifier assemblies worsen
Solution Approach 1:
Dummy rectifier assemblies are introduced to balance the rotor assembly. These dummy assemblies counterbalance the centrifugal forces and vibrations generated at high rotational speeds, thereby maintaining mechanical stability and reliability while enabling increased rotational speed for higher power generation capacity.
3Stability of the object's composition
If the rectifier assemblies are positioned to reduce shear forces, then the mechanical stability improves, but the device complexity increases due to radial arrangement and dummy assemblies
Solution Approach 1:
The functional rectifier assemblies and dummy rectifier assemblies are integrated into a unified radial configuration on the rotor. This merging of functional and balancing components into a single coordinated system achieves mechanical stability while managing overall device complexity through systematic integration.

AI summary
An electrical machine assembly includes an armature assembly defining a rotational axis and a rectifier assembly including at least one diode and defining a central rectifier axis. The armature assembly is configured and adapted to be coupled with a rotor shaft for relative rotation therewith. The central rectifier axis is at a non-parallel angle relative to the rotational axis. A rectifier assembly includes a first diode and a second diode stacked with the first diode. The rectifier assembly includes an AC terminal positioned between the first diode and the second diode and a DC positive output pin electrically coupled to the first diode. A portion of the AC terminal extends outward from the rectifier assembly at a non-parallel angle relative to the central longitudinal axis of the rectifier assembly. A central longitudinal axis of the rectifier assembly can be parallel to the DC positive output pin.
