PROBLEM TO BE SOLVED: To provide a field of a linear motor of high thrust and low loss which has no problem in production property and reliability, along with a linear motor with the same. SOLUTION: In the field part of a linear motor, a field yoke 70 in which electromagnetic steel plates are stacked is equipped with a field where a plurality of magnets for field are arranged side by side toward a length direction. Here, the plurality of magnets for field (main magnetic pole 801 and sub magnetic pole 802) are configured in halbach array. A magnet insert hole 71 is provided inside the magnetic yoke 70 into which the magnet is inserted. COPYRIGHT: (C)2011,JPO&INPIT |
