摘要： An electric drive motor for a work apparatus includes a stator having two stator poles which are at a distance from one another in the circumferential direction and have respective field windings. The motor has a rotor which rotates between the stator poles and the rotor shaft of the rotor drives a fan wheel. The cooling-air flow generated by the fan wheel enters the stator, flows therethrough and is discharged therefrom. For effective cooling, a pole intermediate space is provided between the stator poles; and, for the cooling-air flow, this space is filled by a non-magnetic guide body to provide a cooling duct delimited by the guide body and the field windings. The guide body is fastened to a support at one stator end and is inserted axially into the stator at the other end thereof.
