Patent ID: 7679255

Claim:
An electrical machine comprising: a stationary main element including a stator; and a rotating main element including a rotor; wherein: one of the stationary main element and the rotating main element includes a magnetic yoke and a plurality of poles of a predefined number of poles; the plurality of poles project radially from the magnetic yoke and are made of SMC (soft magnetic powder iron composite) material; each of the plurality of poles carry a pole winding; the one of the stationary main element and the rotating main element is assembled from at least two modules that are axially adjacent, rigidly connected to one another, and respectively produced from the SMC material; each of the at least two modules includes a yoke part closed in on itself of the magnetic yoke and having an equal number of divisions of the plurality of poles attached thereto; the equal number corresponds to a certain fraction of a number of the plurality of poles determined by a number of the at least two modules; each pole includes a pole core and a pole shoe in one piece therewith; each one piece is situated at its end at a distance from the yoke part; the pole cores have an axial core width that is greater than an axial width of the yoke part; the yoke part includes notches on an end face thereof facing another other one of the at least two modules for a form locking partial accommodation of the pole cores of an adjoining module; and the pole shoes are aligned with the pole cores in such a way that their bordering edges, extending in a circumferential direction, are aligned when the at least two modules lie against each other.
