A rotor with a structural coating on the stator that extends into a recess. (2) The rotor according to claim 1, wherein the recess is a flat portion on the shaft of the electric motor. (3) The rotor according to claim (2), further comprising a plurality of flat portions arranged at equal intervals around the shaft. (4) The rotor of claim (1), wherein the structural coating is an epoxy paint. (5) The rotor according to any one of claims (1) to (4), wherein the flat portion is provided at an end of the stack. (6) A rotor according to any one of claims (1) to (4), wherein the flat portion extends below an end of the stack of laminations. (7) The rotor includes a deep-drawn can-shaped steel case, a permanent magnet housed in the case, and an end cap that holds a brush gear and is attached to the case, and the rotor is connected to the end cap and the a laminate stack comprising a shaft rotating on a bearing mounted on a case, a commutator and an armature mounted on the shaft, the armature being fixed on the shaft; and a recess provided on the shaft. A small horsepower PMDC motor including a structural coating extending over the length of the shaft, thereby preventing movement of the stack along the shaft.
