ABSTRACT:
A direct current linear motor and drive unit are described which, together with contributing to reduced size of the apparatus and so forth on which they are equipped, achieve reduction of costs.
These effects are achieved by separating at least one of each of the separate portions of a coil substrate and circuit substrate for at least two armature coils and its drive circuit each, and either connecting with a long, unseparated substrate or removing at least one of the separate portions to shorten said long substrate, thereby allowing an optimum stroke to be obtained which coincides with the operating stroke required by the apparatus and so forth on which it is to be equipped.
In addition, a direct current linear motor is described which achieves reduction of costs by reducing the number of parts.
This effect is achieved by providing a plurality of spacers for preventing deformation of a coil substrate caused by tightening force during fastening of that coil substrate, and forming each into a single unit.
