Abstract
Provided is a fan motor. The fan motor comprises an outer housing, a motor front cover and a motor back cover. A stator and a rotor are arranged in the motor front cover. The motor back cover and the motor front cover are fixed. The motor front cover comprises an inner shell and an outer shell which are made by means of integrated die casting formation. A circular groove is arranged between the outer shell and the inner shell of the motor front cover. Reinforcing ribs are arranged in the circular groove. The reinforcing ribs are sheet-shaped, block-shaped and strip-shaped. The sheet-shaped reinforcing ribs are arranged between the outer shell and the inner shell. The motor front cover of the fan motor is a die casting, and comprises the inner shell and the outer shell. The stator and the rotor are arranged in the inner shell. The reinforcing ribs with multiple structures are arranged between the inner shell and the outer shell. The motor back cover is only fixed at the top of the inner shell to ensure that an enough heat dissipation space is kept between the motor back cover and the outer shell. With the design of the double shells and the reinforcing ribs, the structural strength of the fan motor is increased and the overall heat dispersion performance and the concentricity of the motor are further improved.
