Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-4, a kind of finite angle brushless moment motor, comprise electric machine casing 3, be positioned at the front end housing 4 of described electric machine casing 3 both sides and rear end cap 2 and be positioned at described electric machine casing 3 center and run through the motor shaft 5 of described front end housing 4 and described rear end cap 2, the outside of described rear end cap 2 is also fixedly connected with heat dissipating housing 1, be provided with circuit board 7 in described heat dissipating housing 1, described circuit board 7 is fixed by described motor shaft 5.
The side of described electric machine casing 3 is provided with equally distributed fin 6, described rear end cap 2 end face, described circuit board 7 end face, described heat dissipating housing 1 end face and described heat dissipating housing 1 side opening are provided with multiple equally distributed louvre, and described circuit board 7 is provided with multiple fan 8.This design makes described finite angle brushless moment motor not only can be dispelled the heat by fin 6, can also be carried out heat distribute by numerous described louvres.Because sinking path is more, so this finite angle brushless moment motor interior heat can be passed to the external world rapidly, thus radiating efficiency is significantly promoted.
Each described fin 6 comprises a main leaf and is fixedly connected on auxiliary of described main leaf both sides.Because this design can increase the area that heat transmits, so can accelerate the speed that this finite angle brushless moment motor heat distributes further.
In order to increase the area that described heat transmits further, be less than 60 ° so be set to by the angle between described auxiliary and described main leaf.This design can make described auxiliary of described main leaf both sides installation greater number, and namely along with the increase of described auxiliary quantity, described heat-transfer surface and area of dissipation also in expansion, thus improve the radiating efficiency of described finite angle brushless moment motor further.
In order to easy to process, thus shorten the production time of this finite angle brushless moment motor, reduce its production cost, so the louvre of the louvre of described rear end cap 2 end face, described circuit board 7 end face and the louvre of described heat dissipating housing 1 end face are strip.Function due to described heat dissipating housing 1 is the described circuit board 7 of protection, so the louvre of described heat dissipating housing 1 side is set to circular hole.This design accelerates the radiating efficiency of described finite angle brushless moment motor under the minimum prerequisite of described circuit board 7 intensity reducing amount.
In order to improve air velocity in described finite angle brushless moment motor further, thus accelerating the emission rate of its internal heat, being more than or equal to four so the quantity of described fan 8 be set to, and being uniformly distributed on described circuit board 7.Wherein, described circuit board 7 is also provided with power line, and described power line is by described circular hole external power supply.Due to the setting of described circular hole without the need to resetting special power circuit pipeline again, this design more advantages of simple.
