Abstract
A synchronous motor includes multiple coil segments, each of which has an iron core in the form of a core stack that is wound with a coil. The coil segments are characterized in that the coils press fastening elements having at least two legs against two opposite surfaces of the substantially right parallelepiped iron core. In each case, at least one leg of the fastening element abutting against the iron core is pressed against the iron core, and at least one free leg of the fastening element projects away from the iron core. The free legs are fastened to connecting elements that connect multiple coil segments to one another.
