ABSTRACT:
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.
