Latest Patents
Cheewoo Lee holds a patent for a two-phase switched reluctance machine that utilizes discontinuous core structures as the stator. This design aims to provide low-cost, high-performance drives. The discontinuous stator core structure features short flux paths and maximum overlap between the rotor and stator poles, regardless of rotor position. Notable configurations of this core structure include E-core, L-core, and I-core designs. By using less steel and magnet wire than conventional SRM designs, this innovation results in significant cost savings for stator and winding materials. The efficiency of this novel SRM is enhanced due to shorter flux paths, which reduce core losses, and decreased phase resistance, leading to lower copper losses. Additionally, the two-phase simultaneous excitation of this SRM minimizes torque ripple during commutation compared to existing two-phase SRMs.
