Problems solved by technology

With the development of modern industry and the improvement of people's living standards, and according to the needs of the market, various requirements are put forward for the motor. In the existing technology, there are many types of motors with different functions. The traditional motor has a simple structure and a single function. , there are many defects. In the field of motors, there are many types of new brushless motors, but some products have a single operation form and often fail. The motor casing often leaks electricity, causing potential safety hazards. High energy consumption, relatively serious wear, high temperature and poor heat dissipation conditions will cause damage to many internal components, reduce the service life of the motor, and increase cost input, which is not conducive to the development of the enterprise

Embodiment approach 1

[0012] Embodiment 1, such as figure 1 , 2 , 3, a dual-power disc brushless DC motor, including a rotating shaft 1, sealed ball bearings 3, 14, positioning ring 4, motor housing 7, coil assembly 8, rotor disc 10, motor rear cover 12, Hall sensor 17, the rotor disk 10 is sleeved in the middle of the rotating shaft 1, and the two surfaces of the rotor disk 10 are respectively embedded with S pole permanent magnets 9 and N pole permanent magnets 11, which are tightened and fixed by M4 flat head screws 16, and the two sides of the rotor disk 10 Coil assemblies 8 are provided respectively, sealed ball bearings 3, 14 are respectively provided at the left and right ends of the rotating shaft 1, the motor housing 7 and the motor rear cover 12 are respectively sleeved on the sealed ball bearings 3, 14 on the left and right ends of the rotating shaft 1, and then The circlips 2 and 13 are fixed and connected together, and the positioning ring 4 is installed between the right-end sealed b...

Embodiment approach 2

[0013] Embodiment 2, the present invention can also be applied in the field of wind power generation. In the case of weak wind, the wind power generator does not need a high-power motor, so only one coil assembly 8 in the motor is required to run to generate electricity, which is beneficial to saving. When the wind generator is under strong wind conditions, a high-power motor is needed at this time. At this time, let the two coil assemblies 8 run simultaneously to generate electricity, and choose single power or dual power according to the needs. It is easy to operate and has various operating modes. One machine with multiple functions , to expand the field of use.

Abstract

The invention discloses a dual-power disc type DC (direct current) brushless motor which comprises a rotation shaft, sealing ball bearings and Hall sensors, wherein a rotor disc is sleeved at the center of the rotation shaft; an S-pole permanent magnet and an N-pole permanent magnet are embedded into the two surfaces of the rotor disc respectively and fixedly screwed down by an M4 grub screw; a coil component is arranged on the two sides of the rotor disc respectively; the sealing ball bearings are arranged at the left and right ends of the rotation shaft respectively; a motor shell and a motor rear cover are sleeved on the sealing ball bearings on the left and right ends of the rotation shaft respectively and fixedly connected together by a clamp spring; the motor shell and the motor rear cover are connected through an M5 inner hexagon screw; and multiple Hall sensors are arranged on the coil components. In the invention, the two coil components can be started at the same time or a single-power mode or dual-power mode is adopted according to the need; the motor can be switched at will between the single-power mode and the dual-power mode; and the motor has the advantages of stable operation, low noise and vibration, low fault rate, safety and energy conservation, little abrasion, reliable performance and long service life, is convenient to operate and easy to manufacture, and saves material.

Description

technical field [0001] The invention relates to a motor, in particular to a dual-power disc-type DC brushless motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque, which is used as a power source for electrical appliances or various machines, and converts mechanical energy into electrical energy. At present, the most commonly used is to use heat energy, water energy, etc. to drive the generator rotor to generate electricity. With the development of modern industry and the improvement of people's living standards, and according to the needs of the market, various requirements have been put forward for the motor. In the existing technology, there are many types of motors with different functions. The traditional motor has a simple structure and a single function. , there are many defects. In the field of motors, t...
