Definitions

  • the present invention relates to a motor with a heat dissipation structure and, more particularly, to a motor which has a sleeve being integrally formed with a plurality of wind-catching projections and has a cooling fan which can induce airflow to quickly enter the motor's housing via the wind-catching projections to dissipate the heat accumulated in the motor.
  • motors are widely used in industry for providing mechanical power.
  • the rotor assembly including an armature core formed by an iron core wound with enameled wire, a commutator, a brush unit, etc.
  • the magnets in the motor's housing will generate heat and thus cause a temperature rise.
  • the heat accumulated in the motor's housing may cause the brush unit to contain more carbon deposits, thus affecting the electrical circuit of the motor.
  • high temperature resulting from the armature core may reduce the magnetic intensity of the magnets used in the motor. Thus, the performance of the motor will be gradually reduced.
  • emergency repair kits which are commonly used in daily life, employ a low-power motor to drive a compressor unit therein for repairing punctured tires.
  • the Traffic Act stipulates that, when a vehicle has a punctured tire on a highway, the driver should repair the punctured tire within a specified period and should immediately drive away after the repair is completed to prevent rearward bump.
  • the motor of the compressor unit of an emergency repair kit should be operated at a higher speed.
  • the performance of the motor will decrease. Even worse, the enameled wire of the armature core will probably be damaged to cause a short circuit, and thus the motor may burn out.
  • a motor is usually installed with a cooling fan at its output shaft.
  • the airflow induced by the cooling fan can only flow along the outer surface of the motor's housing.
  • the heat generated by the armature core, especially the enameled wire, in the motor is not easy to be taken away.
  • the problem of a motor being subject to heat accumulation has not yet been overcome.
  • One object of the present invention is to provide a motor with a heat dissipation structure, which comprises a substantially cylindrical housing, a rotor assembly, a cover, a sleeve, and a cooling fan.
  • the housing defines a plurality of upstream through holes at its circumferential wall and a plurality of downstream through holes at its end closure wall.
  • the sleeve is closely fitted around the circumferential wall of the housing.
  • the sleeve is integrally formed with a plurality of wind-catching projections, around the circumferential wall of the housing, such that each wind-collecting projection is located above one of the upstream through holes of the housing, wherein each wind-catching projection defines an air guiding channel facing towards the cooling fan and communicating with one of the upstream through holes of the housing, so that the airflow induced by the cooling fan can easily pass through the air guiding channels and the upstream through holes to enter the housing, and can go out of the housing via the downstream through holes to take away the heat generated in the motor, so that heat is not easy to accumulate in the motor, and thus maximum power output of the motor can be achieved. Therefore, the performance and service life of the motor can be increased.
  • FIG. 1 shows a 3-dimensional view of a motor according to one embodiment of the present invention.
  • FIG. 2 shows a 3-dimensional view of the motor, which is viewed from a different angle than FIG. 1 .
  • FIG. 3 shows a partially exploded view of the motor.
  • FIG. 4 shows an exploded view of the motor.
  • FIG. 5 shows a plan view of the motor.
  • FIG. 6 shows a sectional view of the motor taken along line A-A in FIG. 5 , wherein the airflow entering the motor's housing is demonstrated.
  • FIG. 7 shows a sectional view of the motor taken along line B-B in FIG. 5 , wherein the airflow entering the motor's housing is demonstrated.
  • FIG. 8 shows a sectional view of the motor taken along line C-C in FIG. 5 , wherein the airflow entering the motor's housing is demonstrated.
  • FIG. 9 shows a schematic view of the motor, wherein some of the airflow flows along the outer surface of the motor's housing by way of recesses is demonstrated.
  • a motor which comprises a substantially cylindrical housing 1 , a rotor assembly, a cover 2 , a sleeve 3 , and a cooling fan 4 .
  • the housing 1 has a circumferential wall which terminates at a flat closure wall 101 (a front end of the motor) and opens out at an opening 102 (a rear end of the motor) which is opposite to the flat closure wall 101 .
  • 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 .
  • the circumferential wall of the housing 1 defines a plurality of upstream through holes 10 .
  • the housing 1 is provided with a pair of opposite magnets 12 at the inner surface of its circumferential wall.
  • the rotor assembly which is located in the housing 1 , includes a number of washers 13 , 181 , 182 , a thrust ring 14 , an adjustment ring 15 , a rotating shaft 16 , an armature core formed by an iron core 171 wound with enameled wire 172 , a commutator 173 , a varistor 174 , an oil-resistant ring 18 , an electrical terminal unit 19 , a compression ring 191 , and a brush unit 192 .
  • a first end of the rotating shaft 16 is mounted to the first bearing 11 at the flat closure wall 101 of the housing 1 (see FIG. 2 ).
  • the cover 2 is provided with a second bearing 21 at its center and mounted to the housing 1 for sealing the opening 102 of the housing 1 .
  • a second end of the rotating shaft 16 of the rotor assembly is mounted at the second bearing 21 (see FIG. 1 ).
  • the cooling fan 4 is installed to the second end of the rotating shaft 16 of the rotor assembly, near the cover 2 .
  • the sleeve 3 which can be made of a non-metallic material, is closely fitted around the circumferential wall of the housing 1 .
  • the sleeve 3 is integrally formed with a plurality of wind-catching projections 31 , around the circumferential wall of the housing 1 , such that each wind-collecting projection 31 is located above one of the upstream through holes 10 of the housing 1 .
  • Each of the wind-catching projections 31 is a bulging layer which has a curved roof 311 and two slant walls 312 , 313 at two sides of the curved roof 311 , wherein the curved roof 311 extends outwardly and towards the cooling fan 4 .
  • each wind-catching projection 31 and the circumferential wall of the housing 1 define an air guiding channel 314 facing towards the cooling fan 4 and communicating with one of the upstream through holes 10 .
  • a recess 32 is defined between two adjacent wind-catching projections 31 .
  • the cooling fan 4 When the motor is running, as shown in FIGS. 5 through 9 , the cooling fan 4 is rotated to induce airflow, which can pass through the air guiding channels 314 and the upstream through holes 10 to enter the housing 1 , wherein the air guiding channels 314 , which faces towards the cooling fan 4 , can effectively collect most part of the airflow induced by the cooling fan 4 to enter the housing 1 and finally to go out of the housing 1 via the downstream through holes 103 , so that the heat generated by the rotor assembly in the motor can be quickly dissipated.
  • the heat generated by the brush unit 192 and the commutator 173 see FIGS. 6 and 7
  • the heat generated by the iron core 171 and the enameled wire 172 see FIGS.
  • the sleeve 3 can be made of a magnetically permeable metal to further increase the performance of the motor.
  • the present invention is featured in that the sleeve 3 is integrally formed with a plurality of wind-catching projections 31 , each of which has one curved roof 311 and two slant walls 312 , 313 at two sides of the roof 211 , wherein the curved roof 311 extends outwardly and towards the cooling fan 4 .
  • the curved roof 311 , the two slant walls 312 , 313 of each wind-catching projection 31 , and the circumferential wall of the housing 1 define an air guiding channel 314 facing towards the cooling fan 4 and communicating with one of the upstream through holes 10 of the motor's housing 1 .
  • the cooling fan 4 when the motor is running, the cooling fan 4 is rotated to induce airflow, which can easily pass through the air guiding channels 314 and the upstream through holes 10 to enter the motor's housing 1 , and can finally go out of the housing 1 by way of the downstream through holes 103 to quickly take away the heat generated by the rotor assembly in the motor, so that heat is not easy to accumulate in the motor's housing 1 . Therefore, the performance and service life of the motor can be increased.
