1Productivity
If high current rated switches are used to operate the motor efficiently, then the motor can be operated efficiently, but the device complexity and cost increase
Solution Approach 1:
The patent replaces the conventional mechanical/electrical switch system with a magnetic resonance-based energy transfer system. The tuned circuit generates resonant oscillations that couple magnetically between the driver coil and motor coil, eliminating the need for high current switches. This substitution of the control mechanism fundamentally changes how energy is transferred to the motor, achieving efficient operation through resonance rather than direct high-current switching.
Solution Approach 2:
The patent changes the operating parameters by utilizing magnetic resonance at a specific frequency. By tuning the circuit to resonate at the natural frequency of the motor coil-LC circuit, the system achieves maximum energy transfer efficiency without requiring high current switches. The resonant frequency parameter becomes the key control variable instead of switch current ratings.
2Ease of operation
If conventional electro-magnetic reciprocating engines are used, then mechanical motion can be produced, but high current rated switches are required which poses technical challenges
Solution Approach 1:
The patent replaces the conventional switch-based control system with a magnetic resonance coupling system. The tuned circuit generates resonant oscillations that automatically couple energy to the motor coil, eliminating mechanical switches and their associated reliability issues. The system operates through passive magnetic coupling rather than active switching components.
Solution Approach 2:
The system utilizes the natural resonant frequency of the motor coil-LC circuit to self-regulate energy transfer. Once the tuned circuit is excited, the resonance automatically maintains optimal energy coupling without requiring external switching control. The system serves itself through resonant oscillations, eliminating the need for complex switching control mechanisms.
