Abstract
A linear motor has a support portion 311 laterally bridged between a plurality of armatures 30 and a shifter side base portion 33 located on a shifter 3 side, for moving along a stator 2 in such a state that a distance between the shifter side base portion and the stator 2 is almost constantly maintained, and the support portion 311 is supported by the shifter side base portion 33 so as to determine a gap between the armature 30 and a magnet 20. Then, the gap between the armature 30 and the magnet 20 of the stator 2 is properly maintained.
Claims8
Linear motor having a slender long stator, a shifter located so as to face said stator, a plurality of magnets located on said stationary side and a plurality of armatures located on said shifter side so as to face said magnets, for moving said shifter along said stator by switching voltage applied on said armature, said linear motor comprising:
- a support portion laterally bridged between a plurality of said armatures;
- and
- a shifter side base portion located on said shifter side, for moving along said stator in such a state that a distance between said shifter side base portion and said stator is almost constantly maintained together with a movement of said shifter;
- whereby said support portion is supported by said shifter side base portion so as to determine a gap between said armature and said magnet.
