Abstract
An electric machine, particularly a miniature electric motor, includes a stator structure provided with at least one pair of main poles and at least one pair of auxiliary poles, the auxiliary poles alternating with the main poles. Each main pole is comprised of a main pole core and a main pole winding on the respective main pole core. Each auxiliary pole is comprised of an auxiliary pole core and an auxiliary pole winding on the respective auxiliary pole core. A holding arrangement holds the auxiliary pole windings in place on the auxiliary pole cores and includes holding fingers extending in direction parallel to the axis of the stator structure into the intermediate spaces between adjoining main and auxiliary pole windings, and furthermore includes a holding ring to which the holding fingers are connected at one end, the holding ring lying against one axial side of the stator structure.
