A series motor with a commutator and commutating winding, in particular for a braked power tool with a universal motor, is disclosed, having a stator which has a stator plate bundle that forms a closed yoke, having at least two field windings and at least one commutating winding, which is laid into grooves of the stator plate bundle. The stator plate bundle has, in the region of the axial ends of the at least one commutating winding, lateral grooves running transversely to the axial direction of the stator for receiving the ends of the at least one commutating winding, so that the commutating winding can be received flush in the stator plate bundle and thus the axial size of the stator can be shortened while output remains the same.

[ I claim:] [1.] A series motor comprising:a rotor extending in an axial direction and arranged rotatably within a stator;a stator plate bundle forming a closed yoke and having an axial length, said stator plate bundle comprising two axial ends each of which having an end surface;axial grooves provided on said stator plate bundle for receiving at least one commutating winding, each said commutating winding comprisingan axial end;at least two field windings; andlateral grooves extending transversely to the axial direction in the vicinity of said axial ends of said stator plate bundle, said axial and lateral grooves being arranged to receive the commutating windings such that the axial ends of the commutating windings are received at least partially within the lateral grooves and protrude beyond the end surfaces of the stator plate bundle at most by half of a thickness of the commutating windings.
