Latest Patents

Among his latest inventions is the brushless vibration motor. This motor features a unique design where a bracket has a burring part protruding upwards. A shaft is fitted at one end into the burring part, while a stator comprises at least one coil provided on the upper surface of the bracket. The rotor includes a rotor yoke fitted over the circumferential outer surface of the bearing, a magnet coupled to the rotor yoke, and a weight that causes eccentric rotation. Notably, this brushless vibration motor does not require a separate casing, enhancing spatial utilization.

Another significant invention is the flat type vibration motor. This motor includes a bracket with a shaft mounted at its central portion. A lower substrate and a magnet are adhered to the upper surface of the bracket, while a casing covers the upper portion, defining an internal space. An upper substrate features a commutator on its lower surface, with a coil and a weight adhered to its upper surface. A resin member is provided on part of the upper substrate, holding a bearing that is rotatably supported by the shaft. A brush is secured to the lower substrate and contacts the commutator, forming a contact part.
