Abstract
A motor 2 has a motor flange 6 for supporting the weight of the motor and is installed on a blower casing 5. The motor flange 6 has a dimension in the radial direction of the motor which is smaller than the outer diameter of the fan 1 and extends in the radial direction of the motor 2 from an outer peripheral portion of the motor 2. A motor casing 5 is formed by a flange portion 5a having an outside installing portion 5m and an inside supporting portion 5n, and a cylindrical shaped housing portion 5b. The outside installing portion 5m has a dimension in the radial direction of the motor which is larger than the outer diameter of the fan 1 and the inside supporting portion 5n has a dimension in the radial direction of the motor which is smaller than the outer diameter of the fan 1. The motor 2 is installed on the blower casing 4 through the outside installing portion 5m of the motor casing 5. Due to the configuration of the housing portion 5b, a space s is formed which establishes a non-contacting condition between the inner peripheral portion of the housing portion 5b and the outer peripheral portion of the motor 2, except for the motor flange 6, and the motor 2 is enclosed outside of the blower casing 4 by the housing portion 5b.
