SINGLE-SPINDLE LINEAR MOTOR, MULTI-SPINDLE LINEAR MOTOR, AND PART TRANSFER APPARATUS

摘要

The present invention relates to a linear motor provided with a magnetic body and an armature. The liner motor is adapted to produce a force causing the magnet body and the armature to be relatively displaced along a given linear moving direction by interaction of magnetic fluxes generated between the magnetic body and the armature during an operation of supplying electric power to the armature. In a typical aspect, the linear motor of the present invention comprises a movable section attached to a base plate adapted to set the moving direction on a base surface thereof, in such a movable manner as to relatively reciprocate along the moving direction with respect to the base plate. A mover is provided on the movable section and formed as one of the magnetic body and the armature. A stator is provided on the base surface of the base plate in such a manner as to be disposed opposed to the mover in a widthwise direction, and formed as the other one of the magnetic body and the armature to extend along the moving direction. A standing wall is provided on an outer peripheral edge of the base plate at least at a position which is along the moving direction, to define a containing space in cooperation with the base surface. The containing space is opened to allow the stator, the mover, and the movable section to be selectively mounted therein and removed therefrom in a direction perpendicular to the base surface.
