Abstract
The utility model relates to a heat abstractor of motor, including two radiator fan, rotor shaft and rotor core, wherein the rotor core tightly overlaps at the rotor shaft, and radiator fan includes wheel hub and sets up the fan blade more than a slice on wheel hub, and two radiator fan pass through wheel hub and tightly overlap on the rotor shaft and arrange the both sides that the rotor was unshakable in one's determination respectively, its characterized in that the both ends that the rotor was unshakable in one's determination are provided with annular boss respectively, and one side of heat dissipation fan blade is provided with radiating bottom plate, and radiating bottom plate hugs closely on the terminal surface of boss. The utility model discloses owing to adopt the both ends that the rotor is unshakable in one's determination to be provided with annular boss, one side of heat dissipation fan blade is provided with the heat dissipation bottom plate, and the structure on the terminal surface of boss is hugged closely to the heat dissipation bottom plate, and it is not only the radiating effect good, has prolonged the life of enameled wire greatly, has indirectly reduced the motor cost, and simultaneously, the heat dissipation bottom plate also plays the effect of strengthening rib, makes fan blade non-deformable, and in addition, there is not the problem that matches in fan blade and the rotor both ends boss, consequently.
Description
Technical field
The utility model is a kind of heat abstractor of motor, particularly a kind of heat abstractor of ac capacitor motor.
Background technology
Traditional motor radiating device, a kind of is to go out blade at cast-aluminum rotor two ends boss direct casting, rotor rotation, blade agitation air are given motor radiating, the heat abstractor of this structure, problem such as blade is yielding when having transportation; Another is to adopt the interior annular groove of fan blade and two ends boss to match, groove width, the depth like this, and corresponding fan blade difference, unfavorable universal component, standardization is poor.
Summary of the invention
[0003] the purpose of this utility model is to consider above-mentioned and a kind of not only good heat dissipation effect is provided, and can effectively reduce motor cost, the heat abstractor of the motor that versatility is high.
The technical solution of the utility model is: a kind of heat abstractor of motor, comprise two radiator fans, armature spindle and rotor core, wherein rotor core tightly is enclosed within on the armature spindle, radiator fan comprises wheel hub and is arranged on the above fan blade of a slice on the wheel hub, two radiator fans tightly are enclosed within on the armature spindle by wheel hub and place the both sides of rotor core respectively, the two ends that it is characterized in that described rotor core are respectively arranged with annular boss, one side of heat radiation fan blade is provided with radiating bottom plate, and radiating bottom plate is close on the end face of boss.
Described radiating bottom plate, fan blade and wheel hub integrated injection molding.
Described radiating bottom plate is shape ringwise, and the length of blade of its profile and fan blade is all corresponding with rotor core.
Described fan blade is evenly distributed in 15.
Described fan blade is eight.
The outside bent angle of described fan blade is circular-arc.
The utility model is owing to adopt the two ends of rotor core to be provided with annular boss, and a side of heat radiation fan blade is provided with radiating bottom plate, and radiating bottom plate is close to the structure on the end face of boss, it is good heat dissipation effect not only, prolong the useful life of enamelled wire greatly, reduced motor cost indirectly, simultaneously, radiating bottom plate also plays the effect of reinforcement, make fan blade not yielding, in addition, do not have the problem that matches in fan blade and the rotor core two ends boss, therefore, help the fan blade generalization.
