A felling head for a forestry machine configured adapted to cut timber, the felling head comprising:

• a support frame, wherein the support frame comprises an accumulation pocket, an accumulating arm, and a harvest arm;
• a stator coupled to the support frame, the stator having coils thereon adapted to produce a time varying stator magnetic field;
• a rotor having at least one of a set of slots and a set of permanent magnets mounted thereon facing the stator and adapted to produce at least one of an axially directed flux and a radially directed flux;
• wherein the rotor is rotatably coupled to the stator in axial alignment therewith by the time varying stator magnetic field, and
• wherein the rotor further comprises a saw blade, the rotor and the saw blade creating a unitary body, the saw blade adapted to cut timber.
