Latest Patents
Ahn Byong-Ho's patent, titled "Low loss permanent magnet motor," describes a back EMF controlled, synchronous, permanent magnet motor capable of extremely high rotation speeds at high efficiency. The design includes a permanent magnet flux source and excitation coils that produce a rotating magnetic field mounted on an iron-free form. This configuration substantially eliminates core loss and resulting rotor drag. The back EMF is determined directly from the excitation, controlling the excitation to maintain a torque angle of approximately 90 degrees between the magnet and coil fluxes. The motor's permanent magnet provides a high flux density, allowing for low current in the motor coils, which reduces coil copper losses and further improves efficiency.
