The brushless motor with the rapid heat dissipation function drives the magnet yoke through the rotation of the main shaft, and the fan blade on the magnet yoke rotates to generate wind power, so that the temperature rise of the motor is greatly reduced; the fan on the magnet yoke generates wind power, so that the air circulation rate between the interior of the shell and the outside can be improved more effectively, the heat in the shell can be radiated to the outside more effectively, and the brushless motor is less prone to generating faults due to large heat productivity; simple structure need not additionally install the fan, has reduced the space volume, has alleviateed product weight, makes the product lighter-weighted.
Description
Technical Field
The utility model relates to the technical field of motors.
Background
The brushless motor is also called a brushless direct current motor, and the brushless direct current motor consists of a motor main body and a driver, and is a typical electromechanical integrated product. The existing part of brushless motors has the problems of large heat productivity when working for a long time and poor heat dissipation due to too fast temperature rise, thereby easily causing motor faults.
Meanwhile, the existing heat dissipation mode is additionally provided with a fan, so that the motor is large in size, heavy in weight, complex in structure and inconvenient to assemble.
SUMMERY OF THE UTILITY MODEL
In order to solve the poor scheduling problem of current brushless DC motor radiating effect, the utility model provides a brushless motor with quick heat dissipation function.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a brushless motor with quick heat dissipation function, yoke 1 is installed on axle 3, 1 externally mounted rotor magnet steel 4 of yoke, 4 externally mounted casing 9 of rotor magnet steel, casing 9 rear portion installation rear end housing 8, casing 9 front portion installation front end housing 7, installation bearing 2 between front end housing 7 and the axle 3, yoke 1 is used for the yoke ring 11 outsides and rotor magnet steel 4 between the integral type installation blade 12 of being connected with axle 3.
The blades 12 are fan-shaped blades.
The brushless motor with the rapid heat dissipation function drives the magnet yoke through the rotation of the main shaft, and the fan blade on the magnet yoke rotates to generate wind power, so that the temperature rise of the motor is greatly reduced; the fan on the magnet yoke generates wind power, so that the air circulation rate between the interior of the shell and the outside can be improved more effectively, the heat in the shell can be radiated to the outside more effectively, and the brushless motor is less prone to generating faults due to large heat productivity; simple structure need not additionally install the fan, has reduced the space volume, has alleviateed product weight, makes the product lighter-weight.

In the figure: 1. the magnetic yoke comprises a magnetic yoke 2, a bearing 3, a shaft 4, rotor magnetic steel 5, a stator iron core 6, a stator winding 7, a front end cover 8, a rear end cover 9, a shell 10, a key groove 11, a magnetic yoke ring 12 and a blade.
Detailed Description
The utility model discloses a brushless motor structure with quick heat dissipation function is shown in fig. 4, yoke 1 is installed on axle 3, 1 externally mounted rotor magnet steel of yoke 4, 4 externally mounted casings 9 of rotor magnet steel, 9 rear portion installation rear end housing 8 of casing, 9 front portion installation front end housing 7 of casing, installation bearing 2 between front end housing 7 and the axle 3, yoke 1 is used for the fan-shaped blade 12 of integral type installation between 11 outsides of yoke ring and the rotor magnet steel 4 of being connected with axle 3, as shown in fig. 1-3.
In a simple way, the magnetic yoke 1 for supporting the rotor is deformed into a fan form, so that the magnetic yoke not only has the function of supporting the rotor magnetic steel 4, but also has the function of heat dissipation, and the traditional heat dissipation fan is omitted. The product structure is simplified, and the product weight is reduced; simple structure is favorable to saving motor inner space to the motor dispels the heat to the radiating mode of initiative, and the heat-sinking capability is strong, protection motor that can be better.
Through designing into the yoke fan blade form, not only play the effect of supporting rotor magnet steel, can play axial fan's effect moreover, 3 pivoted in-process fan rotations in the pivot have greatly improved the utilization ratio of energy, can more effectual improvement casing inside and the external air circulation rate between, can be more effectual with the inside heat dissipation of casing to external, make brushless motor be difficult to more because calorific capacity is big and produce the trouble.
During the use, with brushless motor circular telegram, 3 pivoted drive yoke 1 rotations in the time of pivot, yoke 1 rotates with moving fan blade 12 is whole, and simultaneously, yoke 1 rotates together with magnet steel 4, when fan blade 12 rotates, can blow the inside heat of casing to the external world, and simultaneously, can also with the inside of external cold wind pumping to casing 9, very big improvement the inside and the casing 9 of casing between the external gas circulation rate, at the in-process of gas circulation, the inside temperature of casing effectively reduces.
