Description

Technical Field

[0001] The utility model 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 in which the stator is a permanent magnet or a coil, and the rotor is a coil or a permanent magnet.

[0003] Most of the existing electric vehicle drive motors adopt this kind of DC motor. The polarity of the permanent magnet is directly opposite to the polarity of the coil. The two drive the rotor to rotate through attraction and repulsion. Since the force generated by the direct opposite polarity is either zero or the maximum value, and there are certain speed limit requirements for the motor speed, it is difficult to increase the speed.

[0004] Therefore, the drive motor with such a structure has a low energy conversion rate, no advantage in energy consumption, an unsatisfactory cruising range, and greatly restricts people's travel. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an outer rotor type magnetic vortex motor.

[0006] The outer rotor type magnetic vortex motor that can overcome the deficiencies of the prior art includes a stator and a rotor. The difference is as follows:

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

[0008] 2. The rotor includes left and right rotating wheels. Each rotating wheel includes a coaxial wheel sleeve and an obliquely arranged wheel rim Ⅱ. Wheel spokes Ⅱ are evenly distributed between the wheel sleeve and the wheel rim Ⅱ. Powerful magnets are evenly surface-mounted on the inner circumference of the wheel rim Ⅱ to form a magnetic ring.

[0009] 3. The wheel sleeves of the left and right rotating wheels are respectively sleeved on the left and right ends of the wheel shaft and are installed on the shaft body through corresponding ball bearings. The left and right wheel rims Ⅱ are connected. The inverted "V"-shaped polarity formed by the left and right magnetic rings is matched and opposite to the "△"-shaped polarity.

[0010] The further optimized scheme is as follows:

[0011] 1. 120 radial winding grooves are evenly distributed on the circumference of the "△"-shaped ring body.

[0012] 2. The number of surface-mounted powerful magnets is 20.

[0013] 3. In the windings of three phases A, B, and C, each phase winding is wound in 4 winding grooves, with 4 turns wound in each winding groove. After winding 4 winding grooves with an interval of 8 winding grooves, the process is repeated until the winding of this phase is completed.

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

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

[0016] Furthermore, each spoke II is made in the shape of a fan, which is convenient for ventilating and cooling the winding group and the strong magnet, and prevents the strong magnet from demagnetizing and the winding group from burning out due to excessive temperature.

[0017] Furthermore, it further includes a wheel surface coaxial with the rim II. The wheel surface is connected to the rim II through an annular plate. Rib plates are evenly distributed among the wheel surface, the rim II, and the annular plate. The left and right annular plates are connected by bolt assemblies evenly distributed in the circumferential direction to realize the connection of the left and right rims II.

[0018] Advantages of the present utility model:

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

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

The axle body of the axle 1 is large in the middle and small at the left and right ends (which are respectively the installation positions of the inner rings of the left and right bearings). The rim I is designed as a "△" - shaped ring body 2 (its cross - section is an isosceles triangle). 120 radial winding grooves 2-1 are evenly distributed on the circumference of the "△" - shaped ring body 2. Four evenly distributed spokes I 3 are connected between the middle axle body of the "△" - shaped ring body 2 and the axle 1. The A, B, and C three - phase windings are star - connected in the winding grooves 2-1 of the "△" - shaped ring body 2 to form a "△" - shaped polarity, as shown in Figure 4(a) and Figure 4(b).

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

[0034] Each phase winding is wound in four winding grooves 2-1. Four turns are wound in each winding groove 2-1. After skipping eight winding grooves 2-1, then wind in four winding grooves 2-1, and repeat continuously until the winding of this phase winding is completed.

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

[0037] The runner includes a hub sleeve 4 (with a mounting hole position for the outer ring of the bearing), a rim II 5, and a wheel surface 8 coaxially arranged from the inside to the outside. The rim II 5 is located on the left side of the hub sleeve 4 and slopes leftward and outward. The angle between the inner circumferential surface of the rim II 5 and the axis is 52°. Twenty strong magnets 7 are pasted on the upper surface of the inner circumferential surface of the rim II 5 to form a magnetic ring on the right side. Four obliquely arranged spokes II 6 are circumferentially and evenly connected between the rim II 5 and the hub sleeve 4, and each spoke II 6 is made in the shape of a fan blade. The left and right end faces of the wheel surface 8 are flush with the end faces of the rim II 5 and the hub sleeve 4 respectively. A ring plate 9 is welded between the left end of the wheel surface 8 and the left end face of the rim II 5. Bolt holes are circumferentially and evenly arranged on the ring plate 9. Rib plates 10 are circumferentially and evenly welded between the ring plate 9, the wheel surface 8, and the rim II 5. As shown in FIGS. 5(a) and 5(b), Figure 6 shown.

[0038] The winding fixing wheel is assembled in the left and right runners in the following way:

[0039] The hub sleeves 4 of the left and right runners are coaxially sleeved on the left and right end heads of the wheel shaft 1 respectively. The left and right hub sleeves 4 are installed on the left and right end heads of the wheel shaft 1 through corresponding ball bearings 11. The left and right rims II 5, 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 rims II 5.
