Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a vacuum cleaner motor. Background Art

[0002] With the improvement of the quality of life, the use of vacuum cleaners is becoming more and more common, and the vacuum cleaner motor is the heart of the vacuum cleaner. The fan part of the vacuum cleaner motor can include a coaxially arranged fixed impeller and a moving impeller. The main function of the fixed impeller is to release the wind flow generated by the moving impeller more effectively.

[0003] However, as motors continue to be miniaturized, there are major heat dissipation issues that need to be addressed during the design process: (1) After miniaturization, the cross-sectional area of ​​the brush is reduced, which increases the current density, causing the brush temperature to rise, exacerbating brush wear, and failing to meet life requirements during use; (2) Due to the influence of the traditional vacuum cleaner structure, the brush assembly of the vertical vacuum cleaner motor on the market is installed far away from the cooling fan end, resulting in poor heat dissipation after miniaturization, and the motor temperature rise does not meet the requirements. At the same time, the existing vacuum cleaners have poor vacuuming effects due to insufficient rotation speed and insufficient suction. Therefore, it is necessary to design a vacuum cleaner motor. Summary of the invention

[0004] The object of the present invention is to provide a vacuum cleaner motor to solve the technical problem that the suction force of the existing vacuum cleaner motor is not strong enough.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A vacuum cleaner motor comprises an electric drive, a stator assembly, a rotating shaft and a rotor assembly. The rotor assembly is arranged on the rotating shaft, the stator assembly is arranged outside the rotor assembly, and the electric drive is arranged outside the stator assembly.

[0007] Furthermore, the above scheme also includes a skeleton, which is arranged at the front and rear ends of the electric drive, the stator assembly and the rotor assembly, and the skeleton is arranged between the stator assembly and the rotor assembly to separate them.

[0008] Furthermore, the above also includes a support bracket and a shell, the support bracket and the shell are arranged to cover each other, and the frame, electric drive, stator assembly and rotor assembly are all arranged inside the support bracket and the shell.

[0009] Furthermore, the above scheme also includes a support bearing, two support bearings are respectively arranged in the support bracket and the outer shell, one end of the rotating shaft is arranged on the support bearing in the support bracket, and the other end of the rotating shaft passes through the support bearing in the outer shell and is arranged outside the outer shell.

[0010] Furthermore, during the electromagnetic design of the vacuum cleaner motor, the load coupling effect of the vacuum cleaner is considered through several target optimization parameters, so that the speed of the vacuum cleaner motor reaches 190,000 rpm.

[0011] Furthermore, information on the response speed requirements of motors for dust, carpets and hard floors of different materials is collected. According to the working principle of the motor, a physical model including the rotor structure and the stator winding layout is constructed to ensure accurate simulation of the internal magnetic field distribution of the motor and its changes over time. According to actual usage, dynamic load curves representing different cleaning scenarios are established, covering different working conditions from light to heavy. The efficiency, torque density, noise and vibration control are taken as the optimization goals, and the geometric dimensions and electrical parameters of the motor are set as the parameter range. The electromagnetic field finite element analysis of the established motor model is performed using ANSYS Maxwell software, and the magnetic flux density and inductance parameters under different working conditions are calculated. The vacuum cleaner load model is coupled with the motor model, and the particle swarm optimization method is used to automatically search for the best combination of motor parameter sets, so that each optimization goal can be better met, and the motor design plan is output.

[0012] Furthermore, the vacuum cleaner motor has a built-in intelligent sensor that can monitor the motor status in real time and automatically adjust the speed and torque as needed.

[0013] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0014] (1) The present invention adopts an ultra-high-speed motor as the basis, and considers the load coupling effect of the vacuum cleaner in the electromagnetic design through multi-objective optimization parameters. The core brushless motor has an extremely high speed and can provide strong suction. The ultra-high-speed motor speed can reach 190,000 revolutions per minute, making the vacuum cleaner perform well in cleaning dust and debris. It provides power support for cleaning multiple scenes such as the whole house floor, bed, narrow gap, desktop, etc., and can quickly suck up both granular debris and fine dust.

[0015] (2) The maximum operating efficiency of the machine can reach 91.8%, which means that the energy conversion efficiency is very high and can convert electrical energy into mechanical energy to the maximum extent. Advantages: High efficiency reduces energy consumption and extends the working time and service life of the equipment.

[0016] (3) Use high-quality bearings and materials, as well as an advanced heat dissipation system to ensure long-term stable operation of the motor. Advantages: Improves the overall reliability and durability of the motor and reduces maintenance costs. Intelligent control function: Built-in intelligent sensors can monitor the motor status in real time and automatically adjust the speed and torque as needed. Advantages: Intelligent control improves the flexibility and convenience of operation while protecting the motor from overload damage. BRIEF DESCRIPTION OF THE DRAWINGS
