  • Patent number: 5760500
    Abstract: An XY table that uses linear electromagnetic actuators to achieve faster operating speeds, improve durability, prevent generation of dust and reduce size (make more compact). The cord for supplying electrical power to the linear electromagnetic actuators and the cords for obtaining signals from each type of sensor are concentrated at an intermediate movement member (X table), and gathered together into a single cord that is used for connection to the outside (controller, etc.). As a result, detrimental effects caused by the cord are minimized which enables the XY table to demonstrate the performance described above.
