A work apparatus has a tool which is driven in rotation by a drive motor via a transmission. The drive motor is an electric motor which has a commutator and brushes. The drive motor is arranged in a motor housing and drives an impeller wheel which conveys a cooling airflow for the drive motor. Simple and effective lubrication of the transmission is achieved with the cooling airflow flowing past the commutator and brushes and the transmission is arranged downstream of the commutator in the cooling airflow. The motor housing is formed in a manner closed toward the transmission housing on that end side that faces the transmission housing and is connected to the transmission housing via a flow connection. |
