Description
Technical field
The invention belongs to technical field of motors, and in particular to a kind of rotor.
Background technology
Motor is used for realizing the conversion of electric energy and mechanical energy and mechanical energy and electric energy, and the rotor of motor is iron core, set at present
The magnetic stripe composition of the axle fastener hole at the center of rotor core and the peripheral part in rotor core is put, but because rotor exists
Under high-speed cruising, substantial amounts of heat can be produced, and motor does not allow easy heat radiation at work, causes electromotor high-temperature to be easy to burn out and make
The defects of into economic loss.
Existing patent No. CN106208466A, discloses a kind of rotor, including armature spindle and some rotor punchings, described turn
The center of sub- punching is provided with the axis hole for being used for placing armature spindle, and the rotor punching is circumferentially laid with some placement magnetic stripes
Mounting hole；Also include some radiating groups, the radiating group is located on rotor punching, and the radiating group corresponds the installation
Hole, the radiating group include strip louvre and interface channel, and the mounting hole site is logical in the outside of heat emission hole, the connection
Road connects mounting hole and heat emission hole respectively so that T-shaped between mounting hole and heat emission hole.The patent is effectively guaranteed motor and turned
Son operationally can effectively be radiated, and improve the service life of rotor.But the patent rotor is using process
Leakage field and demagnetization easily occur for middle magnetic stripe so that the efficiency step-down of rotor.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to which a kind of fan thermal effect of now offer is good, the electricity of demagnetization is not easy
Machine rotor.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of rotor, including rotor core,
Its innovative point is：The rotor core centre offers shaft hole, and rotating shaft, institute are installed with inside the shaft hole
The periphery for stating rotor core is spaced apart and is provided with multiple magnetic stripe mounting holes, is also spaced apart on the rotor core and is provided with two circle radiatings and leads to
Road, the heat dissipation channel are divided into the first heat dissipation channel and the second heat dissipation channel, first heat dissipation channel and the second heat dissipation channel
It is spaced, first heat dissipation channel is located at the second heat dissipation channel outer layer, first heat dissipation channel and the second heat dissipation channel
Corresponding with magnetic stripe mounting hole one by one, first heat dissipation channel is connected with magnetic stripe mounting hole by the first interface channel, and described
Two heat dissipation channels are connected with magnetic stripe mounting hole by the second interface channel.
Further, the heat dissipation channel and interface channel directly form a T-type structure.
Further, first interface channel and the second interface channel are uniformly arranged on the inside of rotor core.
Beneficial effects of the present invention are as follows：
（1）The present invention, to being radiated inside magnetic stripe mounting hole, reduces magnetic by the way that heat dissipation channel is connected with magnetic stripe mounting hole
The damage of bar, improve the service life of rotor；
（2）The present invention reduces the demagnetization phenomenon between magnetic stripe by setting two circle heat emission holes, and the arrangement being spaced.
Brief description of the drawings
Fig. 1 is the top view of the present invention；
Fig. 2 this use new sectional view.
Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
As depicted in figs. 1 and 2, a kind of rotor, including rotor core 1, the centre of rotor core 1 offer rotating shaft
Hole 2, rotating shaft 3 is installed with inside shaft hole 2, the periphery of rotor core 1, which is spaced apart, is provided with multiple magnetic stripe mounting holes 4, rotor
Also it is spaced apart on iron core 1 and is provided with two circle heat dissipation channels, heat dissipation channel is divided into the first heat dissipation channel 5 and the second heat dissipation channel 6, and first
The heat dissipation channel 6 of heat dissipation channel 5 and second is spaced, and the first heat dissipation channel 5 is located at the outer layer of the second heat dissipation channel 6, the first radiating
The heat dissipation channel 6 of passage 5 and second is corresponding with magnetic stripe mounting hole 4 one by one, and the first heat dissipation channel 5 and magnetic stripe mounting hole 4 pass through first
Interface channel 8 is connected, and forms a T-type structure, and the second heat dissipation channel 6 is connected with magnetic stripe mounting hole 4 by the second interface channel 7
Connect, be similarly formed a T-type structure, heat dissipation channel is connected with magnetic stripe mounting hole, to being radiated inside magnetic stripe mounting hole 4,
The damage of magnetic stripe is reduced, improves the service life of rotor, while the first heat dissipation channel 5 and the second heat dissipation channel 6 are spaced
Arrangement, reduce the demagnetization phenomenon between magnetic stripe.
First interface channel 8 and the second interface channel 6 are uniformly arranged on the inside of rotor core 1, are advantageous to inside
Radiating.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention
