Patent ID: 8384251

Claim:
A linear and curvilinear motor system, comprising: a pair of right and left linear and curvilinear guiding devices that movably guide and respectively support right and left of a slider, each provided with a guide rail and slider blocks, the slider being disposed with and facing toward a fixed base, the guide rail being configured by linear tracks and a circular arc track, the guide rail provided on a surface of the fixed base, the slider blocks being connected to the slider and configured to slide along an uppermost surface of the guide rail; a motor unit provided with a stator having both a linear section and a circular arc section and provided for the fixed base and a mover having a linear section and provided for the slider and away from the stator with a gap interposed therebetween, such that the slider is moved reciprocatingly along a length direction of the linear and curvilinear guiding devices with respect to the fixed base; and a position detecting device that detects positions of the linear tracks and the circular arc track, wherein 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 a position detection point is defined as: r=λm/γm.
