摘要： A linear and curvilinear motor system includes: linear and curvilinear guiding devices movably guiding and respectively supporting right and left of a slider, each having a guide rail configured by linear tracks and a circular arc track and slider blocks; a motor unit having a stator with a stator linear section and a stator circular arc section and a mover with a linear section and provided for the slider and away from the stator with a gap interposed therebetween; and an encoder head and a hole sensor detecting positions of the linear tracks and the circular arc track. When a magnetic pole pitch of the linear section of the stator is a distance λm and a magnetic pole pitch of the circular arc section of the stator is an angle γm, a radius r of the circular arc track at the position detection point is defined as r=λm/γm.

摘要： Provided is a linear motor device which is compact even when a stroke is increased, which can reduce heat generation, and which can eliminate damping force caused by circulating current. The linear motor device includes a linear motor that includes a movable member having a plurality of fields and a stator in which a plurality of armatures including polyphase coils are arranged in line in the moving direction of the movable member, and a controller that sequentially outputs control commands to current amplifiers respectively connected to the armatures in accordance with the relative position of the movable member. The controller selectively outputs the control commands to only the current amplifiers corresponding to the armatures which are opposite the movable member such that the armatures are positioned within a range corresponding to the length in the moving direction of the movable member.
