Abstract
The utility model discloses a fan motor structure that can force heat dissipation, include the motor casing of constituteing by procapsid and back casing, install stator module in the motor casing, be provided with the rotor subassembly in the stator module, be connected with the motor shaft on the rotor subassembly, casing and back casing location before this motor shaft both ends are respectively, and the procapsid terminal surface is provided with a plurality of preceding louvres, is provided with a plurality of back louvres on the back casing, and preceding louvre passes through the motor casing intercommunication with the back louvre. Due to the adoption of the fan motor structure, when the fan works, air flow generated by the fan blades enters the motor shell through the rear heat dissipation holes and is discharged from the front heat dissipation holes, so that cold air passes through the inside of the whole motor and takes away heat, the effect of reducing the temperature rise of the motor is realized, the motor is prevented from being overheated, the stable working performance of the motor is guaranteed, and the service life of the motor is prolonged. In addition, as only the heat dissipation holes are required to be processed on the end face of the front shell, the production difficulty of the product is reduced, the production cost of the product is reduced, and the competitiveness is improved.
Description
Technical Field
The utility model relates to a motor structure, especially a fan motor structure.
Background
The fan motor generates a large amount of heat during operation, and therefore, a heat dissipation structure is necessary to be disposed on the motor. In the prior art, the heat dissipation structure of the fan motor generally adopts the structure that heat dissipation holes are formed around a motor casing, and a centrifugal fan blade is further installed on a motor shaft in order to improve the heat dissipation effect of a part of the fan motor. However, the heat dissipation effect of the heat dissipation structure of the fan motor still cannot achieve the ideal effect in the actual use, the heat dissipation holes are formed in the periphery of the motor shell, the production difficulty of a product is increased, the motor shell is easy to deform, the concentricity of the motor shell and the stator is poor, the performance of the motor is reduced, and the running noise of the motor is high.
Disclosure of Invention

In order to solve the technical problem, the utility model discloses a fan motor structure that can force heat dissipation, include the motor casing of constituteing by procapsid and back casing, install stator module in the motor casing, be provided with the rotor subassembly in the stator module, be connected with the motor shaft on the rotor subassembly, casing and back casing location before this motor shaft both ends are respectively, the procapsid terminal surface is provided with a plurality of preceding louvres, is provided with a plurality of back louvres on the back casing, preceding louvre passes through the motor casing intercommunication with the back louvre.
The motor shaft is provided with an axial flow fan blade, and the axial flow fan blade is located between the rotor assembly and the front shell. The axial-flow fan blade can push out hot air in the motor shell under the drive of the motor shaft, so that the air flow in the motor shell is accelerated, and the heat dissipation effect of the motor is further improved.
The procapsid end connection has the motor mounting panel, be provided with on this motor mounting panel with the heat dissipation through-hole that preceding louvre corresponds has injectd the air current and can only discharge from the heat dissipation through-hole after preceding louvre, can flow with higher speed air current, makes the motor radiating effect better.
The procapsid and the rear housing side are provided with preceding connection journal stirrup and back connection journal stirrup respectively, and preceding connection journal stirrup corresponds the cooperation with back connection journal stirrup and passes through the screw connection fixed, make the motor equipment more convenient, and the product structure is more stable.
The front radiating holes are four and evenly and circumferentially distributed on the end face of the front shell, so that the front shell is convenient to produce and process and has better attractiveness.
The utility model has the advantages that: in this kind of fan motor structure that can force radiating, the casing terminal surface is provided with a plurality of preceding louvres, be provided with a plurality of back louvres on the back casing, preceding louvre passes through the motor casing intercommunication with the back louvre, the air current that the flabellum produced when the fan work gets into motor casing by back louvre, discharge in the past louvre, make cold air through whole motor inside and take away the heat, realize radiating effect rapidly, prevent that the motor from overheated, the stable working property of guarantee motor, reduce motor noise, extension motor life. In addition, as only the heat dissipation holes are required to be processed on the end face of the front shell, the production difficulty of the product is reduced, the production cost of the product is reduced, and the competitiveness is improved.
