[0002] The magnetic levitation swing motor is an advanced motor technology that uses the principle of magnetic field to achieve rotor suspension and swing. Its main feature is that it does not require mechanical bearings, which significantly reduces friction loss and enables the motor to achieve high-speed operation and high-precision control.

The swing frame assembly 2 includes a first swing frame 21 and a second swing frame 22 arranged in parallel and vertically. There is a gap between the first swing frame 21 and the second swing frame 22 to facilitate swinging. The swinging directions of the first swing frame 21 and the second swing frame 22 are always opposite. The movable subassembly 3 is fixed on the swing frame assembly 2 and corresponds to the two ends of the coil 12. The mover assembly 3 includes a first magnet component 31 symmetrically fixed on both sides of the inner wall of the first swing frame 21 and a second magnet component 32 symmetrically fixed on both sides of the inner wall of the second swing frame 22.

[0041] In this structure, the coil is arranged horizontally, and the first magnet is installed on both sides of the first swing frame corresponding to the coil, and the second magnet is installed on both sides of the second swing frame corresponding to the coil.

The support protrusion 403 can improve the strength of the swing limiter 4, extend the service life, and achieve a better limiting effect. The swing limiter 4 is symmetrically arranged between the fixed frame 11 and the swing frame assembly 2. The two swing limiters 4 are located on both sides of the spring rod 214. The use of two swing limiters 4 can balance the force and achieve a better limiting effect.

[0045] In some embodiments, Figure 2 , Figure 3 and Figure 6 As shown, the swing limiter 4 is T-shaped, and is rotatably mounted on the upper end of the fixed frame 11 via a connecting shaft 43. The connecting shaft 43 is located between the first waist-shaped hole 401 and the second waist-shaped hole 402, and an axial hole adapted to the connecting shaft 43 is provided on the swing limiter 4.

[0046] In some embodiments, Figure 3 and Figure 7 As shown, the first swing frame 21 and the second swing frame 22 have the same structure and are both U-shaped.

The two vertical bars 212 correspond to the two ends of the coil 12, which is convenient for installing two magnets. The first magnet 31 and the second magnet 32 ​​are fixed on the inner wall of the corresponding vertical bar 212.

[0047] In some embodiments, Figure 2 , Figure 3 and Figure 7As shown, a spring sheet 5 is connected between the swing frame assembly 2 and the fixed frame 11. Connecting ears 111 are symmetrically arranged on both sides of the lower end of the fixed frame 11, one end of the spring sheet 5 is fixed to the corresponding connecting ear 111 by screws, and elastic plates 51 are symmetrically and spaced apart at the other end of the spring sheet 5.

An inner groove 213 is arranged at the lower end of the first swing frame 21 and the second swing frame 22, and the elastic plate 51 is placed in the inner groove 213 and fixed by a pressing plate 52.

[0048] In some embodiments, Figure 4 and Figure 5 As shown, the first swing frame 21 and the second swing frame 22 are provided with a spring rod 214 extending toward the inside of the fixed frame 11, and the first spring 61 and the second spring 62 are respectively installed between the two sides of the spring rod 214 and the fixed frame 11, and the first spring 61 and the second spring 62 are respectively located on the two sides of the spring rod 214.

One end of the two springs is sleeved on the first positioning column 215, and the other end is sleeved on the second positioning column 112. The first positioning column 215 and the second positioning column 112 can limit the springs to prevent the springs from shifting.

[0049] In some embodiments, Figure 4 As shown, the coil 12 includes a coil frame 121 and a coil set 122 wound on the coil frame 121, and the coil frame 121 is H-shaped; an output rod 23 is installed on the first swing frame 21 or the second swing frame 22, and the output rod 23 is vertically arranged.

[0050] The use process of this magnetic suspension swing motor is as follows:

[0051] See also Figure 8 For example, when the coil 12 is energized, the magnetic field generated is: N pole on the left and S pole on the right; the first magnet 31 on the left is attracted, and the first magnet 31 on the right is repelled, so that the first swing frame 21 swings toward the right; the second magnet 32 ​​on the left is repelled, and the second magnet 32 ​​on the right is attracted, so that the second swing frame 22 swings toward the left. Fig. 9 When the coil 12 changes the direction of the current, the magnetic field generated is: S pole on the left and N pole on the right; the first magnet component 31 on the left is subjected to a repulsive force, and the first magnet component 31 on the right is subjected to an attractive force, so that the first swing frame 21 swings toward the left; the second magnet component 32 on the left is subjected to an attractive force, and the second magnet component 32 on the right is subjected to a repulsive force, so that the second swing frame 22 swings toward the right.
