Latest Patents

Shigun Oh holds a patent titled "Method for manufacturing bonded magnet and method for manufacturing magnetic device having bonded magnet." This patent describes a process where a viscous material is created by mixing an alloy magnetic powder, which is pre-magnetized, with a resin. The resulting viscous material is applied to the upper surface of a center magnetic leg of an E-shaped core. A coil and an I-shaped core are then coupled to the E-shaped core. During the hardening of the resin, an orientation magnetic field is applied using a permanent magnet. This innovative method results in a bonded magnet that is tightly formed in contact with both surfaces defining a magnetic gap between the E-shaped core and the I-shaped core. Shigun Oh's patent is a testament to his expertise and creativity in the field.
