Abstract
In an electrical machine in which the primary part comprises coils and magnets, the coils being surrounded in each case by two tooth halves and the magnet being inserted in each case between said two tooth halves, provision is made according to the invention for an assembly in which the coil is prewound, the prewound coil is pushed onto two tooth halves, and the magnet is only then inserted. This is made possible by the provision of tooth halves which have a corresponding shape or can be converted into a corresponding shape by virtue of the removability of a tooth tip.

A method for constructing a linear motor, comprising the steps of:
- providing a plurality of teeth, each of which having two separate tooth halves with removable tooth tips;
- removing the tooth tips to expose an open end of the tooth halves;
- pushing a prewound coil over the open end of the two tooth halves of each tooth up to an end position;
- and
- inserting a magnet between the two tooth halves of each tooth,
- wherein the tooth halves have a thickness between the open end and the end position which does not exceed a thickness of the tooth halves at the end position.
A tooth half for a tooth of a linear motor, comprising a basic body and a tooth tip provided on an end of the basic body and having a free end, said basic body configured to define an area commensurate with a desired position for attachment of a prewound coil which surrounds two identical such tooth halves, wherein the basic body has a thickness which is sized from the free end up to the desired position such that the thickness does not exceed a thickness of the area commensurate with the desired position, thereby allowing the prewound coil to be pushed on from the free end up to the desired position, when the linear motor is fitted on two identical such tooth halves.
A tooth half for a tooth of a linear motor, comprising a basic body and a tooth tip removably provided to one end of the basic body.
