Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional single, 2-phase, or 3-phase generators are used, then the device can generate electrical energy, but the efficiency is low and power consumption is high
Solution Approach 1:
The generator is divided into four distinct phases with separate stator slots and coil arrangements for each phase. This segmentation allows independent optimization of each phase's magnetic field generation, improving overall energy conversion efficiency while maintaining balanced power output across all phases
Solution Approach 2:
The patent transitions from conventional 1-phase, 2-phase, or 3-phase configurations to a 4-phase system, adding an additional dimensional aspect to the magnetic field generation. This fourth phase enables more uniform distribution of magnetic flux and reduces energy losses through improved phase balancing
2Ease of operation
If conventional generators operate, then electrical energy is generated, but excessive vibrations occur causing rotor unbalance
Solution Approach 1:
The stator slots are arranged with specific asymmetric positioning relative to the rotor magnets, where each phase's slots are offset by 90 degrees electrically. This asymmetric arrangement balances the magnetic pull forces on the rotor, eliminating vibrations while maintaining efficient energy conversion
Solution Approach 2:
The four-phase configuration creates counterbalancing magnetic forces where the pull on one phase is offset by equal and opposite forces from the other phases. This counterweight effect eliminates rotor unbalance and vibrations, enabling smooth operation
3Object-affected harmful factors
If conventional generators consume considerable power, then electrical energy can be generated, but harmful environmental effects and greenhouse gas emissions increase
Solution Approach 1:
The patent converts the previously harmful effect of magnetic flux imbalances and phase asymmetries into beneficial uniform flux distribution through the four-phase configuration. This eliminates energy-wasting magnetic inefficiencies, reducing power consumption and environmental impact while maintaining generation capability

AI summary
The invention relates to a novel 4-phase motor and generator device with increased efficiency for generating electrical energy. The device features a stator wall with eight stator slots and four pole groups, and an armature rotatable within the stator wall. The eight stator slots are divided into four pole groups of opposing stator slots, the two opposing stator slots include a N (North) stator slot and a S (South) stator slot. N and S (South) stator slots are alternatively activated in response to rotation of the armature. The activation of the pole groups results in a rotating magnetic field within the stator wall, and only six of the eight poles are actively coupled in any given configuration. The invention also includes a method of operating the motor for generating electrical energy with increased efficiency and an environmentally friendly manner compared to conventional motors.
