More Information
Summary:An electric blower includes a rotor having a rotating shaft and a rotor core, a motor case that houses the rotor, a centrifugal fan that is an example of a rotating fan that is attached to the rotating shaft to suck outside air, a cooling fan that is attached to the rotating shaft to cool an internal space of the motor case, a first ventilation path through which an air flow is generated by rotation of the centrifugal fan flows, and a second ventilation path through which an air flow is generated by rotation of the cooling fan flows. The cooling fan is positioned between the centrifugal fan and the rotor core, and the cooling fan includes a plurality of first fan blades provided on a first side of the cooling fan, the first side facing the rotor core, and a plurality of second fan blades provided on a second side of the cooling fan, the second side being opposite to the rotor core.
