Claim 9:
10. An electric motor including a stator, the stator comprising a hollow cylindrical stator yoke and comprising a stator star arranged within the stator yoke and including a plurality of radially outwardly extending stator teeth having tips contacting, in an assembled state, corresponding connection positions on an inner circumference of the stator yoke, wherein the stator yoke and the stator star are each formed by a laminated metal sheet pack, wherein the laminated metal sheet pack of the stator star comprises sheet metal layers of stator sheets, closed in a circumferential direction, comprising stator teeth connected with each other via pole shoe bridges and sheet metal layers of individual stator teeth spaced with respect to each other in the circumferential direction, wherein each of the pole shoe bridges has at least one material recess extending in radial direction, and wherein a minimum radial material extension of the pole shoe bridges in region of the at least one material recess corresponds to 0.2 to 0.5 times a radial material extension of the pole shoe bridges outside the region of the at least one material recess.
