Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional rotating electromagnetic machines are used, then basic motor and generator functions are achieved, but efficiency and functionality are limited due to inability to effectively utilize monopole permanent magnet fields of opposite polarities for induction operation
Solution Approach 1:
The rotating electromagnetic machine is designed to operate in dual modes as both a motor and a generator by utilizing monopole permanent magnet fields of opposite polarities. The stator assembly with radially spaced permanent magnets and the rotor with solenoid coils can reversibly convert between electrical energy and mechanical energy, enabling the same device to function as either a motor or generator depending on the direction of energy flow.
Solution Approach 2:
The ferromagnetic core with solenoid coils acts as an intermediary between the external permanent magnets and the internal permanent magnet, transferring energy by induction. The core with its high magnetic permeability facilitates the induction of electric energy from the permanent magnets while transferring this energy to the stator windings, enabling efficient energy conversion in both motor and generator modes.
2Power
If a commutator is used in conventional DC machines, then DC output is achieved, but device complexity increases
Solution Approach 1:
The invention extracts and eliminates the commutator from the conventional DC machine structure. Instead of using a mechanical commutator to produce DC output, the design employs a three-phase stator winding connected to a rectifier bridge, which converts the AC generated by the rotating rotor into DC output. This removal of the commutator simplifies the mechanical structure, eliminates brush wear, and reduces maintenance requirements.
3Use of energy by moving object
If traditional electromagnetic machine designs are used, then basic operation is achieved, but energy transfer efficiency is limited
Solution Approach 1:
The machine employs composite magnetic structures combining permanent magnets with ferromagnetic materials. The stator assembly uses permanent magnets made from composite materials with high magnetic energy products, while the rotor incorporates a ferromagnetic core with high permeability. This composite approach enhances the magnetic field strength and uniformity, improving the induction process and overall energy transfer efficiency between the permanent magnets and the stator windings.
