Optical Dialogue Photonic Converter for Photon-Driven DC Motor System

The photon-driven direct-current (DC) motor system offers significant advantages over conventional switching electricity-driven DC motor system, such as reduced intrinsic electromagnetic interference (EMI), voltage ripple, and improved immunity to environmental EMI, making it a more reliable and efficient solution for motor control. However, the conventional photon-driven DC motor system also presents two drawbacks. Firstly, the power supply and communications are separated, resulting in low system integration. Secondly, the sensors and optical fiber communication require external power source, resulting in high complexity. To address these challenges, this paper proposes an optical dialogue photonic converter (ODPC) for photon-driven DC motor system. The proposed ODPC integrates power supply and communication through a single fiber by utilizing an optical dialogue structure, and eliminates the need for external power source. The proposed ODPC enhances system integration, reduces complexity, and improves reliability, effectively overcoming the limitations of the conventional photon-driven DC motor system. An experimental prototype is built to verify the feasibility and performance of the proposed optical dialogue photonic converter.
