電動芝刈機の電動機冷却構造。[Claims for Utility Model Registration] (1) An electric motor with a cooling fan is mounted on a cutter housing, and the output shaft of this electric motor extends into the cutter housing by passing through an opening provided in the cutter housing. A cutter blade is attached to the output shaft of the electric motor, and the cooling air sent out by the cooling fan passes through a ventilation path formed by the electric motor and a cylindrical wall provided around it.
In the electric lawn mower, the electric motor is cooled and discharged from an opening in the cutter housing into the cutter housing through an air exhaust port provided in the cylinder wall, through a ventilation path provided on the outside of the cylinder wall. A motor cooling structure for an electric lawn mower, characterized in that an exhaust fan is provided in the cutter housing, the fan being rotationally driven by the output shaft of the motor and forcing the cooling air into the cutter housing. (2) The motor cooling structure for an electric lawn mower according to claim 1, wherein the exhaust fan is provided at an output shaft portion of the electric motor. (3) The motor cooling structure for an electric lawn mower according to claim 1, wherein the exhaust fan is provided on the cutter blade.
