Patent number: 6661128Abstract: A two-phase excitation linear motor is provided, having a compact size and a large thrust force simultaneously. Each of two single coils is formed to have an almost rectangular ring-like shape where two sides opposing to each other function as a pair of effective conductors, and the other opposing two sides function as a pair of connecting conductors for connecting between the effective conductors. The connecting conductors are offset at an almost right angle. The two single coils are integrated such that the one effective conductor of the pair of effective conductors of the one single coil is interposed between the pair of effective conductors of the other single coil while the single coils are being combined such that the offset directions of the connecting conductors of the individual single coils are opposite to each other in a direction perpendicular to a traveling direction.Type: GrantFiled: February 8, 2002Date of Patent: December 9, 2003Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Hidehiko Mori, Yasushi Koyanagawa

Patent number: 6584367Abstract: A Y stage is capable of translational driving in the Y-axial direction, by independently controllable Y1 linear motor and Y2 linear motor. The amount of movement of the Y stage is detected by a Y1 linear encoder and Y2 linear encoder, and fed back to a Y control system and &thgr; control system. The Y control system outputs a translational thrust command value, by receiving the average value of each positional detecting value measured by the Y1 linear encoder and Y2 linear encoder as the stage translational direction position feedback value. The &thgr; control system receives the difference between each position detecting value as a stage yawing direction position feedback value, and outputs a yawing direction thrust command value. A non-interference block outputs Y1 linear motor thrust command value and Y2 linear motor thrust command value, by the use of the translational thrust command value and the thrust command value.Type: GrantFiled: June 30, 2000Date of Patent: June 24, 2003Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Kenichi Makino, Yoshiyuki Tomita, Hidehiko Mori

Patent number: 6564110Abstract: A discrete Kalman filter 12 and a disturbance estimating unit 13 are added to a feedback loop for feeding back a detected value of position from a position detector 6. The Kalman filter estimates position and velocity of an object to be controlled, thereafter outputting an estimated value of position and an estimated value of velocity. The disturbance estimating unit estimates from a command value of current and the estimated value of velocity the disturbance that is added to a load 5. The estimated value of position is fed back to a position controller 1, and the estimated value of velocity is fed back to a velocity controller 2. Further, a difference between a target value of current outputted from the velocity controller and the estimated value of disturbance is output as the command value of current.Type: GrantFiled: June 7, 2000Date of Patent: May 13, 2003Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Kenichi Makino, Yoshiyuki Tomita, Hidehiko Mori
