A parallel robot includes a plurality of actuators, a wrist portion, and a plurality of arms that respectively connect the wrist portion to the plurality of actuators. The wrist portion includes a base portion that includes a plurality of connection portions respectively connected to the plurality of arms and a rotation member that rotates about a rotation axis located outside an area surrounded by the plurality of connection portions. The rotation member is provided with a through-hole that is formed along the rotation axis.

Parallel robot

Provided is a magnetic encoder device capable of detecting a rotating angle of an actuator having a cavity structure. The magnetic encoder device includes a ring-shaped rotating body, a ring-shaped permanent magnetwhich is inscribed in and fixed to an inner circumferential side of the ring-shaped rotating bodyand magnetized in a direction perpendicular to a center axis of the rotating body, and a fixed bodywhich is disposed on an inner circumferential side of the permanent magnetthrough an air gap and has a circular circumference and a cavity, and a magnetic field detecting elementdisposed on an outer circumferential side of the fixed bodythrough the permanent magnetand the air gap.

Magnetic encoder device and actuator

An XY table provided with an X-axis table (,) supported on a base movably in the X-axis direction, a Y-axis table (,) supported on the base movably in the Y-axis direction, and a top table (,) movable in the X-axis direction together with the Y-axis table (,), and further provided with an armature (,) of a linear motor (,) mounted on an X-axis base (,) supporting the X-axis table (,), a movable element (,) mounted on the back of the X-axis table (,) and opposed to the armature (,), and armature (,) of a linear motor (,) mounted on a Y-axis base (,) supporting the Y-axis table (,), and a movable element (,) mounted on the back of the Y-axis table (,) and opposed to the armature (,). The top table can be positioned with high precision and moved at high acceleration and deceleration.
