Problems solved by technology

[0006] However, although the above existing methods can dissipate the heat in the motor rotor, they cannot prevent foreign objects from entering the rotor through the perforations.
When this type of fan is in operation, some fine dust, small particles, or water vapor will easily enter the rotor from the perforation, which may cause the shaft of the motor to be blocked by foreign objects and be stuck, or cause the Fault

Abstract

The invention relates to a forced heat emission device of motor, which comprises a stator base and a rotor. Wherein, the rotor rotates relative to the stator base; the rotor comprises a rotor frame and a hub; the rotor frame has one side part and a bottom, while the bottom has at least one through hole; the hub sheathes the rotor frame to avoid foreign matter into the through hole; the hub has several space ribs; when the hub sheathes the rotor frame, each two nearby space ribs and the side part will form a heat emission channel; when rotor rotates, the hot air inside the rotor will pass saidthrough hole and the heat emission channels to be discharge outside the rotor frame.

Description

technical field [0001] The invention relates to a forced heat dissipation structure of a motor, in particular to a forced heat dissipation structure of a motor that can be applied to a fan. Background technique [0002] Motors have a wide range of applications. Fans are one example. They are often used as active components for heat dissipation. Because of their different application ranges, fan motors can be divided into two types: centrifugal and axial. However, basically These two fan motors use the motor to drive the fan blades to rotate, so as to achieve the effect of actively dissipating heat. [0003] Please refer to Figure 1A , which shows a three-dimensional schematic diagram of a conventional centrifugal fan. The existing centrifugal fan 10a uses a motor (not shown) to drive a rotor 12a, and the fan blade 14a of the centrifugal fan 10a is connected to the rotor 12a. When the rotor 12a rotates, it will simultaneously drive the fan blade 14a to rotate. Let the air ...
