More Information
Summary:An electronic pump is provided, which includes a rotor assembly. The rotor assembly includes an impeller and a rotor which are separately injection-molded respectively. The material for injection-molding the rotor includes a magnetic material, and the material for injection-molding the impeller does not include a magnetic material. The impeller includes a first fitting portion, the rotor includes a second fitting portion, the impeller and the rotor are cooperated by the first fitting portion and the second fitting portion, and the impeller and the rotor are fixed with respect to each other by a fixing device. In this way, the impeller and the rotor may be made respectively by different materials, and an ordinary plastic material may be employed for the impeller, which may reduce the cost of manufacturing material of the rotor assembly.
