Engineering Contradiction Analysis
1Power
If three-phase motors are used to meet increasing power demands, then power output can be increased, but current demand increases and efficiency decreases
Solution Approach 1:
The patent divides the motor system into multiple independent phase windings (5 phases instead of 3), creating separate control channels for each phase. This segmentation allows independent optimization of current distribution across phases, enabling higher power output while maintaining lower overall current demand through balanced multi-phase operation.
Solution Approach 2:
The patent changes the fundamental parameter of phase number from 3 to 5 phases, fundamentally altering the electrical characteristics of the motor system. This parameter change enables different current distribution patterns and electromagnetic field configurations that improve efficiency while delivering increased power output.
2Power
If three-phase motors are used to meet increasing power demands, then power output can be increased, but efficiency decreases
Solution Approach 1:
By segmenting the power delivery across 5 separate phases instead of 3, the system distributes energy conversion across multiple winding sets. This reduces energy losses in each individual phase through better current distribution and reduced peak currents, thereby improving overall system efficiency while maintaining high power output.
Solution Approach 2:
The patent employs dynamic control of multi-phase windings through a microprocessor-based controller that independently manages current distribution across all 5 phases. This dynamic control optimizes the electromagnetic field configuration in real-time, minimizing energy losses and maximizing efficiency during varying operating conditions.
3Use of energy by moving object
If the number of phases and electromagnetic coils is increased, then efficiency increases and current demand decreases, but device complexity increases
Solution Approach 1:
The patent designs a universal 5-phase motor architecture that can serve multiple functions and applications. The same 5-phase winding structure and control system handle both power generation and motor operation, reducing overall system complexity compared to having separate systems. The multi-phase design itself provides both efficiency improvement and power factor correction functions simultaneously.
Solution Approach 2:
The 5-phase motor system provides self-service through inherent power factor correction capabilities built into the multi-phase architecture. The system automatically balances current distribution and optimizes electromagnetic field configuration without requiring external correction devices, thereby managing the complexity of multiple phases through self-regulating control.

AI summary
Like a transformer that can increase or decrease AC voltage or current by increasing or decreasing the turns-ratio of the transformer an amplification factor is developed. And like a transistor that can amplify/attenuate an electrical signal and by manipulating the hfe of the transistor, it could increase or decrease the amplification factor of the transistor. Likewise, the MAM unit, depending on the number of phases used, can amplify the power for a given output motor by increasing the number of phases of the output AC motor, which substantially reduces the amount of current an AC motor will draw for a specific amount of torque. By increasing the number of phases on an AC synchronous, asynchronous, axial, induction, or reluctance type motor, using alternating current, you can increase the efficiency, which implies an amplification factor of the motor thereby reducing the applied current required for a given amount of torque/speed.
