Zusammenfassung:An electric motor operated impeller has a drive motor having a motor shaft, a stator and a rotor rotated about a rotary axis, an impeller housing having a receiving casing which extends in direction of the rotary axis of the rotor and accommodating the electric drive motor. The receiving casing has a wall against which the stator of the drive motor radially abuts a bottom and an opposite edge. A support supports the shaft of the motor and is provided with throughflow openings for cooling air. The wall of the casing has at least one channel-shaped expansion extending parallel to the rotary axis and formed so that the expansion is open toward the edge of the casing and closed toward the bottom of the casing. SOPLADOR ACCIONADO POR MOTOR ELECTRICO QUE SIRVE PARA PRODUCIR UNA CORRIENTE DE AIRE. EL SOPLADOR COMPRENDE UNA CARCASA DE SOPLADOR QUE ESTA DOTADA CON UN VASO DE ALOJAMIENTO PARA EL MOTOR DE ACCIONAMIENTO ELECTRICO, QUE SE EXTIENDE EN LA DIRECCION DEL EJE DE ROTACION DEL RODETE DEL SOPLADOR, EL ESTATOR DEL MOTOR DE ACCIONAMIENTO ESTA APOYADO RADIALMENTE EN LA PARED DEL VASO DE ALOJAMIENTO Y LOS ELEMENTOS DE APOYO PARA LOS COJINETES DEL ARBOL DEL MOTOR ESTAN DOTADOS CON ABERTURAS DE PASO PARA EL AIRE DE REFRIGERACION. SE CONSIGUE UNA REFRIGERACION EFECTIVA DEL MOTOR DE ACCIONAMIENTO ELECTRICO SI LA PARED DEL VASO DE ALOJAMIENTO TIENE AL MENOS UN ABOMBAMIENTO A MODO DE CANAL QUE SE EXTIENDE AL MENOS APROXIMADAMENTE PARALELO AL EJE, QUE ESTA ABIERTO HACIA EL BORDE DEL VASO Y ESTA CERRADO HACIA EL FONDO DEL VASO.
