Latest Patents

Hiroshi Sakaba holds a patent for an outer rotor type spindle motor. This design features a shaft and a stator that are supported and fixed to a flange. Damping members are interposed between the flange and the stator, as well as between the flange and the shaft. The flange itself can also be formed of a damping material. This configuration effectively dampens and absorbs electromagnetic vibrations from the stator and rotating vibrations from the shaft. Consequently, the generation of vibration or noise in the flange is prevented, which is often caused by the transmission of electromagnetic vibrations generated on the stator due to alternating current supplied to a stator coil.
