Slider for linear conveyer and linear conveyer

摘要

To provide a linear conveyer and a slider for a linear conveyer that reduce a weight of a slider and in which errors in detecting positions of the sliders are less likely to be caused. The linear conveyer includes a stationary module including a stator and a rail, and a slider including a mover and a rail guide that is fitted on the rail, the slider being movable along the rail by linear motor driving. The linear conveyer detects a position of the slider with a magnetic scale (40A) mounted to the slider and a magnetic sensor mounted to the stationary module. The magnetic scale (40A) includes a plastic magnet (44) and a back yoke (42) on which the plastic magnet (44) is placed. The plastic magnet extends in an extending direction in which the rail extends and has a plurality of magnetic poles. A fixed portion (44A) of the plastic magnet (44) is fixed to the back yoke (42) and a portion of the plastic magnet (44) other than the fixed portion (44A) is movable and deformable relative to the back yoke (42) along the extending direction of the magnetic scale (40A).
