More Information
Summary:The invention discloses an impeller, relating to the structure technology of the fan blades of a motor, comprising a blade retaining plate, and a group of blades uniformly arranged at one side of the blade retaining plate; the impeller is characterized in that another group of blades are uniformly arranged at the other side of the blade retaining plate. As both sides of the blade retaining plate are both provided with blades, the main function of the blades at one side is to discharge the heat in the motor outwards, and the main function of the blades at the other side is to discharge the heat transmitted from an engine outwards; the heat from both sides is directly emitted toward both sides, so the impeller is cooled in time, and the motor is guaranteed to work under low temperature condition. The impeller has the advantages that the structure is simple and reasonable; the reduction of the temperature rise of the motor is facilitated, and the service life of the motor is increased.
