Abstract
The utility model provides a permanent-magnet motor with centrifugal heat radiation. Air inlets and air outlets are arranged on a motor rotor, the heat produced by the rotor is centrifuged and emitted by the centrifugal force produced when the rotor rotates at high speed to implement the heat radiation and the cooling of the motor. The structure of the utility model is that the air outlets are arranged on the bulkhead between magnetic cores on the rotor, and the two end surfaces of the rotor are provided with the air inlets. Thus, air is driven to flow by the centrifugal force to cause the heat produced by the rotor to be emitted when the rotor rotates. The utility model has the advantages that the structure is simple, the heat radiation effect is good, and the phenomenon of power falling caused by degaussing of the magnetic core of the existing permanent-magnet motor under high temperature can be efficiently avoided.
Description
Technical field:
The utility model relates to a kind of improvement of motor, particularly a kind of magneto that has centrifugal heat radiation.
Background technology:
Magneto has obtained using very widely now.Owing to adopt permanent magnetic material as rotor, its stable performance, efficient are higher.But because rotor produces a large amount of heats in high speed rotating, traditional magneto does not have radiator structure, and permanent magnet very easily produces the demagnetization phenomenon under the state of high temperature, therefore cause the decline of power of motor.
Summary of the invention:
The purpose of this utility model provides a kind of magneto that has centrifugal heat radiation.It is provided with air inlet and gas outlet on rotor, the centrifugal force that produces when utilizing the rotor high-speed rotation, centrifugal the distributing of heat that rotor is produced, the natural cooling of realization motor.
The technical solution of the utility model is: a kind of magneto that has centrifugal heat radiation, comprise rotor and stator, and it is characterized in that on the bulkhead between the magnetic core, being provided with the gas outlet on the described rotor, on two end faces of rotor, have air inlet.Like this, when rotor rotation, drive air flows, the heat of its generation is distributed by centrifugal force.
The permanent magnet motor structure that has a centrifugal heat radiation provided by the utility model is simple, has better heat radiating effect, the power decline phenomenon that can effectively avoid the magnetic core of existing magneto at high temperature to demagnetize and cause.
Description of drawings:
Fig. 1 is this permanent magnet machine rotor Facad structure schematic diagram that has centrifugal heat radiation.
Fig. 2 is this rotor end face structure cutaway view.
1-rotor wherein; The 2-rotating shaft; The 3-gas outlet; The 4-bulkhead; The 5-air inlet; The 6-magnetic core.
Embodiment:
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.As shown in Figure 1 and Figure 2, this rotor 1 is made of at interval magnetic core 6 and bulkhead 4, has many gas outlets 3 in the middle of bulkhead 4, and this gas outlet makes the many passages of the inside and outside formation of the magnetic core of rotor, is used for heat radiation.On two end faces of rotor, have air inlet 5.Thus, when rotor high-speed rotates, by centrifugal force drive air according in the air inlet-magnetic core of path-gas outlet-magnetic core flows outward, forms the heat radiation of flowing.
In an embodiment, the passage of gas outlet 3 and magnetic core radially are formed with the forward angle in the bulkhead 4, and the centrifugal radiating effect of air is better during rotor rotation like this.
