Motor assembly and vacuum cleaner having the same

The present invention relates to a vacuum cleaner having a motor assembly, and this, the motor housing; Installed in the motor housing motor generating a suction force; An impeller rotatably installed on the motor rotation shaft; The impeller cover coupled to the motor housing so as to surround the impeller; The motor and disposed between the impeller, is formed on the lower face of the diffuser vanes and the diffuser vanes for converting the sea pressures, some of the air passing through the impeller into static pressure above the pressure rises the air by the diffuser vane motor a guide vane including a plurality of return vanes for forming a flow path for guiding the side; A return vane for generating as the motor is miniaturized - including, a fan of the vacuum cleaner; and a bearing housing provided with a pivot-support section for supporting the rotation axis of the flow path forming unit for forming a flow path in contact with the lower end of the return vanes and the motor correct the incomplete flow path problems and to provide a vacuum cleaner having a motor assembly, and this, for optimum flow passage area. The motor assembly, the bearing housing, the flow path forming portion, the vacuum cleaner
