High-performance photon-driven DC motor system | Nov 2024
The researchers showcase a photon-driven DC motor system, that utilizes optical energy to drive mechanical motion, avoids EMI derived from electrical switching action and immunizes against EMI in conventional electricity-driven DC motor systems
Initially set at 347 rpm with a 40 mNm load, the motor experiences a sudden shift to no-load conditions at 15 s. The abrupt change causes an excess of electromagnetic torque, which leads to an unintended speed increase. Huangfu, Y., Wang, S., Rienzo, L. D. & Zhu, J. Radiated EMI modeling and performance analysis of a PWM PMSM drive system based on field-circuit coupled FEM. Nia, M. S. S., Shamsi, P. & Ferdowsi, M. EMC improvement for high voltage pulse transformers by pareto-optimal design of geometry structure based on parasitic analysis and EMI propagation.
