Description

High efficiency motor housing structure

This creation is a high-efficiency motor casing structure, especially a combination of a magnetically permeable material and an aluminum-extruded heat-dissipating material, thereby maintaining a high-efficiency operation of the motor.

According to the current technology industry, the motor is a driving device that is generally used. The conventional motor is used to induce the work force or power generator through the rotor and the stator.

However, whether it is a large motor with a large power or a small motor that provides a small power, after the starter motor operates the rotor, the rotor includes an armature iron chip, an armature coil, a rectifier structure, and a high magnetic permeability. The stator of the silicon steel sheet will generate high heat, and because the price of the silicon steel sheet is high, the material cost is reduced, so that the volume of the silicon steel sheet is reduced; therefore, when the motor rotates rapidly, most of the high heat generated when the rotor and the stator are operated are Accumulating inside the motor casing, when the heat is not effectively dissipated, the internal temperature of the motor gradually rises, causing the magnetic permeability to decrease, resulting in a gradual decrease in the operating efficiency of the motor; more importantly, when the temperature rises to a certain extent, the armature The insulation of the enameled wire in the coil is more easily destroyed, which causes the armature coil to be short-circuited and burns the motor.

In addition, the conventional motor housing material can be divided into an aluminum motor case and an iron motor case, wherein the aluminum motor case has better heat dissipation; only a poor torque; and the iron motor case contributes to the torque The improvement, but can not effectively transfer high heat to the outside, so it has poor heat dissipation.

The conventional motor mainly transmits some heat loss power to the outside along the motor through the conduction and radiation of the bearing; however, the conventional motor has a poor heat dissipation mechanism, and the heat dissipating component is formed by die casting, so that the rotor is operated under high load conditions. The high heat generated during the operation of the stator cannot be effectively transmitted to the outside world, causing thermal expansion between the stator-fitted steel sheet and the heat dissipating component. In the case of poor heat dissipation, the stator will be loosened, causing abnormality in the operation of the motor.

In view of this, the creator has specially researched and improved the motor performance improvement and motor heat dissipation, and improved the above problems with a better design. After long-term research and development and continuous testing, the creation of this creation began.

Therefore, in order to solve the problem that the high heat generated by the operation of the conventional motor cannot effectively dissipate heat to the outside, the creation of the steel piece of the stator fitting is loosened, thereby causing the abnormal operation of the motor.

In order to achieve the above object, our creator provides a high efficiency motor housing structure comprising: a motor provided with a magnetically conductive element, the magnetically conductive element being made of a first metal; and a thermally conductive element The magnetic conductive element and the heat conductive element are combined with each other by a tube expansion method, and the heat conductive element is made of a second metal.

According to the high efficiency motor housing structure described above, the outer diameter of the heat conducting element is formed with at least one heat dissipating fin.

According to the high efficiency motor housing structure described above, the second metal is a metal having high thermal conductivity.

According to the high efficiency motor casing structure described above, the heat conducting component is made of an aluminum extruded material.

According to the high efficiency motor housing structure described above, the magnetic conductive element has a cylindrical shape, and the inner diameter shape of the heat conductive element corresponds to the outer contour of the magnetic conductive element.

According to the high efficiency motor casing structure described above, the first metal is a highly magnetic metal.

According to the above described high efficiency motor housing structure, wherein the first metal is made of iron.

It is from the above description and settings that it is obvious that this creation has the following several advantages and functions, which are detailed as follows:

1. Compared with the conventional motor, the heat dissipation of the stator causes the loss of the looseness of the stator-fitted steel sheet. This creation can be combined with the high-thermal conductivity metal by the magnetic conductive element with high magnetic permeability and the external expansion tube. The heat conducting element, whereby the high heat temperature generated by the operation of the motor is radiated outward by the heat conducting element.

2. Since the conventional heat dissipating component is made by die-casting, it can not effectively dissipate the generated heat to the outside during operation. Therefore, the outer diameter of the heat-conducting component of the present invention is made of aluminum extruded material, so that the heat dissipation effect is better. In addition, the outer diameter of the heat-conducting element can also form heat-dissipating fins, thereby greatly improving the efficiency of conducting the high-heat temperature generated by the motor operation to the outside, thereby achieving the high-efficiency operation of the motor by using the present invention.

3. Compared with the conventional motor housing material, it is only divided into a single material of aluminum motor case or iron motor case. Therefore, this author considers the advantages of the heat dissipation capability of the aluminum motor case, and the iron motor case contributes to the torque. Enhance the advantages, and then combine the two to enhance the high thermal conductivity of the creation and enhance the effect of the torque.
