Title: Positioning device for linear motor
Inventor: HARA KENJI
IPC: H02P25/06
Filed: 2002-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a positioning device for linear motor of a simple configuration, good in assembly work, and low in cost, with which precise position controlling can be performed in the case where a linear motor provided with a long stator and the stroke of a moving member is abnormally long, is used.  <P>SOLUTION: The positioning device for linear motor is provided with a travel region where a moving member 1 just passes by and a positioning region for positioning the moving member 1 at both ends of a stator 2 along the length direction of the stator 2. Only the positioning region is provided with a scale part 41. The travel region is such region as sensorless vector control is performed without using the scale 41. Thereby, no scale is required to be coupled and connected together for an extended length with precision, for improved workability at assembling. The cost is reduced much as well because the scale is only partially used.  <P>COPYRIGHT: (C)2004,JPO
