Abstract

A motor comprises a metal base, a stator, and a rotor. The metal base combines with a shaft receiver. The stator combines with the metal base. The rotor comprises a hub and a permanent magnet. The hub rotatably combines with the shaft receiver. A air gap forms between the permanent magnet and the stator. Wherein, a radial rotation area forms between the hub and the metal base. A magnetic area forms between the permanent magnet and the metal base. In the radial rotation area, the metal base has an empty region between the magnetic area and the shaft receiver. The empty region has a connecting portion combined with the shaft receiver. In addition, the motor can be applied to a dissipation fan. It can reduce the weight of the motor by setting the empty region.

Description

technical field [0001] The invention relates to a motor and a cooling fan, in particular to a motor with a metal base and a cooling fan using the motor. Background technique [0002] Please refer to figure 1 As shown, a conventional motor 9 is disclosed, and the motor 9 includes a metal base 91 , a stator 92 and a rotor 93 . There is a shaft tube 911 in the center of the metal base 91; the stator 92 is combined with the outer peripheral wall of the shaft tube 911; the rotor 93 includes a hub 931 and a permanent magnet 932, and the rotor 93 is rotatably coupled to the shaft 933 Shaft tube 911, the permanent magnet 932 is arranged on the inner peripheral wall of the hub 931, and there is an air gap between the permanent magnet 932 and the stator 92; thereby, the motor 9 can be applied to a cooling fan, wherein the metal base 91 As shown in the figure, it can be used as a fan frame, and the rotor 93 can be used as a fan wheel. When the cooling fan operates, current can be inp...
