Abstract
The fan motor according to this invention is made of a base plate in the form of almost square plate. At a center of the base is provided a large enough opening. Within the central opening are mounted radially extending fixed blades, and at a center of the fixed blades a stator of the electric motor is fixed. On the other hand, to a rotor of the motor movable blades are fixed, so that the movable blades face the fixed blades. In this structure, the fixed blades serve also as holding or supporting members for the motor, and increases the airflow as well as the efficiency of the fan motor. Since the base and the fixed blades are made integral with each other by molding synthetic resin material, the number of parts as well as the assembly processes can much be reduced, thus enabling to reduce the manufacturing cost.
