Benefits of technology

The present invention provides a motor with a heat dissipation structure. The motor has a hologh housing with a hood that collects the air current generated by a cooling fan. The housing has an upstream and downstream through hole, and the hood is mounted above the upstream hole. This effectively collects the air current and allows it to enter the housing and quickly go out, taking away the heat generated by the rotor assembly. This prevents heat from accumulating in the housing, increases the maximum power output of the motor, and improves its performance and service life.

Problems solved by technology

Thus, heat is not easy to accumulate in the housing, maximum power output of the motor can be achieved, and the performance and service life of the motor can be increased.

Embodiment Construction

[0014]Since motors are commonly used devices, the principles of a motor's operation are not illustrated in the following paragraphs. However, basic elements of a motor will be described in this specification. Referring to FIGS. 1 through 7, a motor according to one embodiment of the present invention is shown, which includes a cylindrical housing 1, in which a rotor assembly and two opposite magnets 12 are provided. The rotor assembly includes a rotating shaft 16, an armature core formed by an iron core 171 wound with enameled wire 172, and a commutator 173. The two opposite magnets 12 are provided at an inner surface of the cylindrical housing 1. The housing 1 has a circumferential wall which terminates at a flat closure wall 101 (a front end of the motor). The flat closure wall 101 is provided with a first bearing 11 at its center and defines a plurality of downstream through holes 103 around the first bearing 11. A first end of the rotating shaft 16 is mounted to the first bearin...

Abstract

A motor includes a cylindrical housing, a cooling fan, and a rotating shaft. The cylindrical housing defines at least one upstream through hole at its circumferential wall. The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor. The hollow hood is mounted to the cylindrical housing such that a head portion is located above the upstream through hole, thus defining an annular air-guiding channel therebetween, which can receive the airflow generated by the cooling fan and guide the airflow to enter the cylindrical housing via the upstream through holes, so that the heat generated therein can be dissipated effectively. Thus, heat is not easy to accumulate in the motor, and the performance and service life of the motor can be increased.

Description

(a) TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a motor and, more particularly, to a motor with a heat dissipation structure capable of restraining temperature therein, wherein the motor is provided with a hollow hood at its housing for collecting the air current generated by a cooling fan provided at a rotating shaft of the motor, wherein one portion of the hollow hood is located above at least one upstream through hole of the motor's housing, so that the air current can quickly enter the housing via the upstream through hole to dissipate heat therein, and thus the performance and service life of the motor can be increased.(b) DESCRIPTION OF THE PRIOR ART[0002]Today, motors are widely used in industry for providing mechanical power. When a motor, irrespective of lower or high power, is running, the rotor assembly (including an armature core formed by an iron core wound with enameled wire, a commutator, a brush unit, etc.) and the magnets in the motor's ho...
