Latest Patents

One of Sata's latest patents is for a dynamic air pressure bearing. This invention improves the performance of a rotor supported at high speed in a non-contact state. The design features a stationary shaft at the center of a housing, with a stator core mounted on a stud. A magnet yoke, which contains both inner and outer magnets, is integrated with a sleeve that rotates relative to the stationary shaft. The rotary polygonal mirror, fixed on the sleeve, rotates at high speed, creating a dynamic air pressure bearing between the shaft and the sleeve. The stationary shaft consists of a main body and a ceramic bearing member with grooves that generate dynamic air pressure.

Another significant patent is for a deflector motor with a gas bearing and magnet thrust bearing. This electric motor utilizes magnetic attraction forces between an annular stator core with toroidal coils and confronting magnets. The design includes a cup-shaped member that serves as a magnet yoke and a seat for the driven element. A cylindrical rotary sleeve is press-fitted into the central portion, contributing to reduced weight, size, and manufacturing costs.
