线性电动机和具有线性电动机的压缩机
摘要：
一种线性电动机，具有筒状外磁轭部(4)，配置于该外磁轭部(4)内的筒状内磁轭部(3)，设于内磁轭部(3)的线圈部(2)，随着线圈部(2)产生的磁通作振动的永久磁铁片(5a、5b)，以及支承该永久磁铁片(5a、5b)的振动体(6)，振动体(6)的材质为磁性材料。因为振动体(6)为磁性材料，故外磁轭部(4)和内磁轭部(3)生成的磁通回路在不受到振动体(6)妨碍的情况下通过振动体(6)，所以线性电动机能高效进行振动运动。
摘要（英）：

A linear motor includes tubular outer yoke (4), tubular inner yoke (3) disposed in outer yoke (4), coil (2) provided to inner yoke (3), permanent magnet (5a, 5b) vibrating following a magnetic flux produced by coil (2), and vibrator (6) made of magnetic material and supporting permanent magnets (5a, 5b). Magnetic loop produced by outer yoke (4) and inner yoke (3) travels through vibrator (6) freefrom interference by vibrator (6) because vibrator (6) is made of magnetic material. As a result, the linear motor vibrates efficiently.
