More Information
Summary:An axial-gap motor-generator includes a case, a rotor, a stator, a cooling plate, an air inlet, an outlet, an airflow generating groove, and a radial groove. The rotor is rotatable around a rotating shaft. The stator is fixed to the case. The stator has a first distal end and a second distal end. The first distal end faces the rotating shaft. The cooling plate is in contact with the second distal end. The stator is disposed between the rotating shaft and the cooling plate. The first distance between the air inlet and the rotating shaft is smaller than a second distance between the air outlet and the rotating shaft. The airflow generating groove is provided between the case and the rotor. The radial groove is provided between the case and the cooling plate via which the airflow generation groove is connected to the air outlet.
