Linear and curvilinear motor system

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.
