Patent number: 10597172Abstract: Disclosed is a magnetic-fluid momentum sphere, which is used for satellite attitude adjustment. The magnetic-fluid momentum sphere comprises stators and a spherical shell. The stators are classified into three groups, axes of the three groups of stators are orthogonal to each other, each group comprises two stators arranged symmetrically about the center of the spherical shell, and the inner surfaces of the stators are spherical surfaces. The spherical shell is formed by combining two hemispherical shells, the material of the spherical shell is a non-ferromagnetic material, the inner surfaces of the stators closely adhere to the outer surface of the spherical shell, there is no relative movement between the spherical shell and the inner surfaces of the stators, and the spherical shell is filled with magnetic fluid. The magnetic-fluid momentum sphere achieves a small size and mass, low costs, and small coupling among the axes.Type: GrantFiled: July 18, 2016Date of Patent: March 24, 2020Assignees: TSINGHUA UNIVERSITY, BEIJING U-PRECISION TECH CO., LTD.Inventors: Yu Zhu, Anlin Chen, Ming Zhang, Kaiming Yang, Rong Cheng

Patent number: 10532832Abstract: A magnetic levitation reaction sphere includes a spherical-housing-shaped rotor and three groups of stators. Each group includes two stators using the sphere center of the rotor as a symcenter. Axes of the three groups are mutually orthogonal. Each stator comprises a stator core and a coil array. An air gap is reserved between an inner surface of each stator core and the outer surface of the rotor. Through grooves are radially formed in the stator cores. The coil arrays are disc-type motor stator windings. Two effective sides of each coil in each coil array are respectively placed in two through grooves of the corresponding stator core. The magnetic levitation reaction sphere has low cost; levitation and rotation driving are integrated; the magnetic levitation reaction sphere has a simple and compact structure, a small size and a low mass, and relates to inherent stable levitation; and the levitation control is simple.Type: GrantFiled: March 15, 2016Date of Patent: January 14, 2020Assignees: TSINGHUA UNIVERSITY, BEIJING U-PRECISION TECH CO., LTD.Inventors: Ming Zhang, Yu Zhu, Anlin Chen, Kaiming Yang, Rong Cheng, Feng Liu, Jinchun Hu, Chuxiong Hu, Dengfeng Xu, Haihua Mu

Patent number: 9995569Abstract: A six-degree-of-freedom displacement measurement method for an exposure region on a wafer stage, the wafer stage comprises a coil array and a movable platform. A planar grating is fixed below a permanent magnet array of the movable platform. A reading head is fixed in a gap of the coil array. A measurement region is formed on the planar grating by an incident measurement light beam of the reading head. The reading head measures the six-degree-of-freedom displacement of the measurement region, so that the six-degree-of-freedom displacement of the exposure region is obtained through calculation. In the method, the six-degree-of-freedom displacement of the exposure region at any time is measured; the measurement complexity is reduced and the measurement precision is improved, and especially, the six-degree-of-freedom displacement of the exposure region can be precisely measured at any time even if the movable platform has high flexibility.Type: GrantFiled: March 15, 2016Date of Patent: June 12, 2018Assignees: TSINGHUA UNIVERSITY, BEIJING U-PRECISION TECH CO., LTD.Inventors: Yu Zhu, Ming Zhang, Anlin Chen, Rong Cheng, Kaiming Yang, Feng Liu, Yujing Song, Fan Zhi, Jinchun Hu, Dengfeng Xu, Haihua Mu, Chuxiong Hu
