<p>The utility model provides a magnet yoke assembling body. With the magnet yoke assembling body adopted, the miniaturization and lightweight of a linear motor can be realized, and high output can be obtained. A linear motor (100) is provided with a magnetic yoke assembling body (30); a field magnet is adopted as a fixed part; an armature (3) is adopted as a movable part; and the field magnet and the armature (3) can move relatively. The linear motor (100) is provided with the magnetic yoke assembling body (30) with magnet columns (14); the magnetic yoke assembling body (30) is provided with two yoke plates (11) which are arranged oppositely, and a yoke fixing part (12) which supports the two yoke plates (11) at one side end portion (11a) of each yoke plate in a cantilever-beam form; and the?clearance?between?the?two?yoke?plates?(11)?is?characterized?in?that?the?clearance?at?one?end?(11b)?is?larger?than?the?clearnce?at?the?other?end?(11a).</p> |
