Problems solved by technology

[0003] However, the above-mentioned existing ceiling fan only has the plurality of cooling holes, so that the high-temperature air around the stator cannot be discharged in time, especially when the ceiling fan is used for a long time, it is more likely to cause high-temperature air to accumulate inside the hub. The ceiling fan is prone to thermal shutdown due to poor heat dissipation, which seriously affects the service life of the ceiling fan

Abstract

A motor and a ceiling fan with the motor are used to solve the existing problem that high-temperature air is easy to accumulate inside the motor, which includes: a support assembly with a shaft; a rotor with a A hub portion on the outer periphery of the hub forming a chamber; a stator combined with the support assembly and located in the chamber; an electrical box having a heat exhaust runner communicated to the outside; and a A heat dissipation fan is located in the electrical box, an air inlet portion of the heat dissipation fan communicates with the chamber, and an air outlet portion of the heat dissipation fan communicates with the heat exhaust runner.

Description

technical field [0001] The invention relates to a motor and a ceiling fan with the motor, in particular to a motor capable of improving heat dissipation efficiency and a ceiling fan with the motor. Background technique [0002] Ceiling fans have been widely used by the public because they do not occupy ground space and have a good air disturbance effect. The existing ceiling fan has a stator and a rotor, the rotor is rotatably combined with the outer circumference of a shaft of the stator, the rotor has a hub for combining multiple fan blades, and the surface of the hub has a plurality of cooling holes; Thereby, the high temperature air around the stator can be discharged through the plurality of cooling holes. An embodiment similar to the conventional ceiling fan has been disclosed in the patent case "Improved Ceiling Fan Motor Structure" of Taiwan Publication No. 525712. [0003] However, the above-mentioned existing ceiling fan only has the plurality of cooling holes, s...
