PURPOSE:To provide a linear scale which can reduce the device size and cut down the cost. CONSTITUTION:This is a linear scale 9 where a linear rail 7 being arranged on stator side so as to guide a mover is made of Mn-Al magnet 49 or over in Rockwell hardness and different magnetic poles are magnetized alternately in the shifting direction of the mover, in the specified positions of this linear rail 7. |
