Problems solved by technology

[0005] However, when the required thrusts of the movers are very different from each other, such as 1000 N for a large-thrust mover and 100 N for a small-thrust mover, the motor specifications will change for the existing linear motor mover structure. too big

Abstract

The invention provides a multi-head type linear motor with an iron core. A multi-head type linear motor with an iron core according to an embodiment includes a permanent magnetic field and an armature. The permanent magnetic field includes P permanent magnets. The armature is arranged to face the permanent magnetic field across a magnetic gap, and includes M armature coils. Either one of the armature and the permanent magnetic field constitutes a mover, and the other constitutes a stator, and a plurality of movers are arranged on the stator so as to individually drive the movers with respect to the stator. In addition, the movers each include a large-thrust mover and a small-thrust mover having different relationships with respect to the stator determined by the number of poles P of permanent magnets and the number M of armature coils, respectively.

Description

technical field [0001] The embodiments discussed here relate to multi-head type linear motors with iron cores. Background technique [0002] A multi-head type linear motor capable of independently driving a plurality of movers by providing movers having the same size on a single stator has been developed as a workbench for, for example, semiconductor manufacturing equipment, electronic component mounting equipment, or machine tools. The linear motor of the feed unit installed. This multi-head linear motor relates to the technology disclosed in Japanese Patent Application Laid-Open No. 2001-211630. [0003] In such a multi-head type linear motor, a mover constituting an armature includes a mover base and a plurality of armature coils wound intensively on an armature core and connected in three phases. On the other hand, the stator constituting the magnetic field is arranged to face the armature across the magnetic gap, and the stator is composed of a yoke and a plurality of...
