Title:
SYNCHRONOUS LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/169046
Kind Code:
A1
Abstract:
A synchronous linear motor 101 is provided with a stator 3 having a plurality of salient poles 11 that comprise a magnetic material, and a movable element 2 arranged facing the salient poles 11 across a gap g. The movable element 2 has a core 14 comprising a magnetic material, a plurality of coils 6, and a plurality of permanent magnets 5 aligned along the movement direction A. The core 14 is equipped with a plurality of teeth 7 projecting from a core back 8 toward the salient poles 11. The coils 6 are wound at least on the teeth 7 on both ends in the movement direction A. The permanent magnets 5 are arranged at the center part of the teeth 7 along the direction in which the teeth 7 project, and the polarity of the magnetic pole of the permanent magnet 5 is the same as the polarity of the magnetic pole facing the adjacent permanent magnet 5. There at least two different shapes in the permanent magnets 5, or at least two that different magnetic characteristics in the permanent magnets 5.
