Description

Technical Field

[0001] The invention relates to a permanent magnet motor, in particular to an outer rotor type magnetic vortex motor. Background Art

[0002] A permanent magnet motor is a DC motor whose stator is a permanent magnet or coil and whose rotor is a coil or permanent magnet.

[0003] The vast majority of electric vehicles currently use this type of DC motor as their drive motor. The polarity of the permanent magnet is directly opposite to that of the coil, and the two drive the rotor to rotate through attraction and repulsion. Since the polarity is directly opposite to each other, the force generated is either zero or maximum. In addition, there is a certain speed limit for the motor speed, so it is difficult to increase the speed.

[0004] Therefore, the drive motor with such a structure has a low energy conversion rate, no energy consumption advantage, and a less-than-ideal cruising range, which greatly restricts people's travel. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention proposes an outer rotor type magnetic vortex motor.

[0006] The outer rotor type magnetic vortex motor can overcome the shortcomings of the prior art. The technical solution includes a stator and a rotor. The difference is:

[0007] 1. The stator is a winding fixed wheel, which includes a coaxial wheel axle and wheel rim I. The wheel rim I is a "△"-shaped ring body. Spokes I are evenly distributed between the wheel axle and the "△"-shaped ring body. The "△"-shaped ring body is star-connected with three-phase windings A, B, and C to form a "△"-shaped polarity.

[0008] 2. The rotor comprises a left wheel and a right wheel, each wheel comprises a coaxial wheel sleeve and an inclined wheel rim II, spokes II are evenly distributed between the wheel sleeve and the wheel rim II, and strong magnets are evenly distributed on the inner circumference of the wheel rim II to form a magnetic circle.

[0009] 3. The wheel sleeves of the left and right rotating wheels are respectively mounted on the left and right ends of the wheel axle and installed on the shaft body through correspondingly arranged ball bearings. The left and right wheel rims II are connected, and the inverted "V" polarity formed by the left and right magnetic circles matches the "△" polarity.

[0010] Further optimization solutions are:

[0011] 1. The “△”-shaped ring body has 120 radial winding grooves evenly distributed on its circumference.

[0012] 2. The number of surface mounts of the strong magnets is 20.

[0013] 3. In the three-phase windings A, B, and C, each phase winding is wound in 4 winding grooves, 4 turns are wound in each winding groove, and then 4 winding grooves are wound after 8 winding grooves, and this process is repeated until the winding of the phase winding is completed.

[0014] 4. The neutral lines of each phase winding are connected.

[0015] Furthermore, the inclination angle of the wheel rim II is 52°.

[0016] Furthermore, each spoke II is made into a fan shape to facilitate ventilation and cooling of the winding group and the strong magnetic field, thereby preventing the strong magnetic field from being demagnetized and the winding group from being burned due to excessive temperature.

[0017] Furthermore, it also includes a wheel surface coaxial with the wheel rim II, the wheel surface and the wheel rim II are connected by a ring plate, ribs are evenly distributed between the wheel surface, the wheel rim II and the ring plate, and the left and right ring plates are connected by bolt assemblies evenly distributed around the circumference to achieve the connection between the left and right wheel rims II.

[0018] Beneficial effects of the present invention:

[0019] 1. The outer rotor type magnetic vortex motor of the present invention has a simple and reliable structure, low energy consumption, and the motor speed is controlled by voltage. The speed is high and can reach 4000 revolutions per minute or even higher.

[0020] 2. The present invention is an innovative design that can be applied to most electric vehicles. It adopts an inverted "V" and "△" type non-straight pole pair structure, which changes the traditional straight structure of strong magnetic and winding group poles. From a mechanical point of view, it is no longer an extreme zero and maximum force output, but an output of force greater than 50% of the maximum value, with small uniform fluctuations, low overall energy consumption and high effective power.

[0031] The outer rotor type magnetic vortex motor of the present invention comprises a winding fixing wheel as a stator and left and right rotating wheels as rotors.

[0032] The winding fixing wheel comprises a coaxial wheel axle 1 and a wheel rim I, wherein a coaxial shaft hole (for axle installation) is provided in the shaft body of the wheel axle 1, the shaft body of the wheel axle 1 is large in the middle and small at the left and right ends (respectively serving as the installation positions of the left and right bearing inner rings), the wheel rim I is designed as a "△"-shaped ring body 2 (whose cross-section is an isosceles triangle shape), 120 radial winding grooves 2-1 are evenly distributed on the circumference of the "△"-shaped ring body 2, and four spokes I3 evenly distributed on the circumference are connected between the "△"-shaped ring body 2 and the middle shaft body of the wheel axle 1, and the winding grooves 2-1 of the "△"-shaped ring body 2 are star-connected with A, B, and C three-phase windings to form a "△"-shaped polarity, as shown in Figures 4(a) and 4(b).

[0033] In the three-phase windings A, B, and C, the winding method of each phase winding is:

[0034] Each phase winding is wound in four winding slots 2-1, 4 turns are wound in each winding slot 2-1, and then 4 winding slots 2-1 are wound after 8 winding slots 2-1, and the process is repeated until the winding of the phase winding is completed.

[0035] Each phase winding is wound in 40 winding slots 2-1, and the three-phase windings A, B, and C are wound in 120 winding slots 2-1. The neutral lines of each phase winding are connected.

[0036] Take the right wheel as an example to illustrate its structure:

[0037] The rotating wheel comprises a wheel sleeve 4 (with mounting holes for the outer ring of the bearing), a wheel rim II5 and a wheel surface 8 which are coaxial from the inside to the outside. The wheel rim II5 is located on the left side of the wheel sleeve 4 and tilted to the left and outside. The angle between the inner ring surface of the wheel rim II5 and the axis is 52°. Twenty strong magnets 7 are attached to the inner ring surface of the wheel rim II5 to form a magnetic circle on the right side. Four oblique spokes II6 evenly distributed around the circumference are connected between the wheel rim II5 and the wheel sleeve 4. Each spoke II6 is made into a fan blade shape. The left and right end faces of the wheel surface 8 are flush with the end faces of the wheel rim II5 and the wheel sleeve 4 respectively. An annular plate 9 is welded between the left end of the wheel surface 8 and the left end face of the wheel rim II5. The annular plate 9 is provided with bolt holes evenly distributed around the circumference. Rib plates 10 are evenly welded around the circumference between the annular plate 9, the wheel surface 8 and the wheel rim II5, as shown in Figures 5(a), 5(b), Figure 6 shown.

[0038] The winding fixing wheel is assembled in the left and right rotating wheels as follows:

[0039] The wheel sleeves 4 of the left and right rotating wheels are coaxially mounted on the left and right ends of the wheel shaft 1, respectively. The left and right wheel sleeves 4 are installed on the left and right ends of the wheel shaft 1 through correspondingly arranged ball bearings 11. The left and right wheel rims II5, the left and right wheel surfaces 8 and the left and right ring plates 9 are aligned. An inverted "V"-shaped ring cavity is formed between the left and right wheel rims II5, and an inverted "V"-shaped polarity is formed between the left and right magnetic circles. The left and right wheel surfaces 8 are flush, and bolt assemblies are arranged in the aligned bolt holes on the left and right ring plates 9. The bolt assemblies evenly distributed around the circumference connect the left and right rotating wheels as a whole, such as Figure 1 , Figure 2 , Figure 3 shown.
