摘要： Provided is a linear motor capable of preventing an increase in length of the armature in the moving direction and also of reducing cogging. The linear motor has a magnetic field part having a plurality of permanent magnets arranged in a straight line in such a manner that N poles and S poles are formed alternately; and an armature having a core which has a plurality of teeth arranged opposite to the magnetic field part with a gap created therebetween and a plurality of coils wound on the teeth of the core. Among the teeth with the coils wound around, a width TW1 in a relative moving direction of each of teeth placed at both ends in the relative moving direction of the armature is smaller, from a base part to an end part thereof, than a width TW2 in the relative moving direction of each of other teeth.

摘要： A track rail is formed in a channel-like configuration while having a guide passage for sliders. A table structure that moves within the guide passage includes: a pair of sliders that move forwards and backwards within the guide passage; and a connecting top board connecting those sliders to each other with a predetermined interval therebetween and provided with a mounting surface for a movable member. An armature constituting a linear motor is received between the pair of sliders, and field magnets constituting the linear motor are arranged in the track rail so as to face the guide passage. The armature and the field magnets, which constitute the linear motor, are completely integrated with the table structure and the track rail, which constitute a linear guide, and are entirely contained inside the linear guide.
