Abstract
The utility model provides a double fan motor belongs to motor technical field. It is poor that it has solved current motor radiating effect, problem that life is low. This double fan motor, including motor housing and install the motor housing in motor housing one end, be provided with stator, rotor and pivot in the motor housing, pivot one end is worn out the motor housing and is connected with external fan outside and stretching into the motor housing in, and the other end of pivot just is located the position department cover that the motor housing is close to the stator and is equipped with built-in fan. The utility model has the advantages of effectively reduce the inside and outside temperature of motor, play splendid radiating effect, improve motor life.
Description
Technical Field
The utility model belongs to the technical field of the motor, a motor, in particular to double fan motor is related to.
Background
At present, the traditional motor adopts a single fan structure, which often causes the technical defects of poor heat dissipation effect, poor structural reliability and short service life.
Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide a double fan motor that the radiating effect is good and longe-lived.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a double fan motor, includes motor housing and installs the motor housing in motor housing one end, motor housing in be provided with stator, rotor and pivot, its characterized in that, pivot one end wear out motor housing outside and stretch into motor housing in-connection and have external fan, the other end of pivot just is located motor housing in the position department cover that is close to the stator and is equipped with built-in fan.
In the above dual-fan motor, the external fan and the internal fan are both composed of a shaft sleeve and a plurality of blades circumferentially and uniformly distributed on the shaft sleeve, and the shaft sleeve is fixedly sleeved on the rotating shaft.
Compared with the prior art, the double-fan motor has the advantages that the double-layer fan design of the external fan and the internal fan is adopted, the temperature inside and outside the motor is effectively reduced, the excellent heat dissipation effect is achieved, and the service life of the motor is prolonged.
Drawings
Fig. 1 is a schematic structural view of the double fan motor.
In the figure, 1, a motor shell; 2. a motor housing; 3. a rotating shaft; 4. an external fan; 5. a built-in fan; 6. a blade; 7. and a shaft sleeve.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, this double fan motor, including motor housing 1 and install the motor housing 2 in motor housing 1 one end, be provided with the stator in motor housing 1, rotor and pivot 3, 3 one ends of pivot are worn out motor housing 1 and are connected with external fan 4 in stretching into motor housing 2, the other end of pivot 3 just is located the position department cover that is close to the stator in motor housing 1 and is equipped with built-in fan 5, external fan 4 comprises by axle sleeve 7 and the blade 6 of a plurality of circumference evenly distributed on axle sleeve 7 with built-in fan 5, axle sleeve 7 is all fixed the cover and is located on pivot 3, carry out effectual heat dissipation inside and outside the motor through double fan's setting, the radiating effect is good, effectively reduce the inside and outside temperature of motor.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
