Detailed Description

The invention will now be further described with reference to the accompanying drawings and detailed description.

First embodiment

As shown in fig. 1 to 3, a novel permanent magnet power machine may include a housing 1, a main shaft 2, 8 sets of rotors 3, and 8 lever mechanisms 4. The main shaft 2 is rotatably mounted on the housing 1, for example by means of bearings 5 at both ends. The 8 groups of rotors 3 are fixed on the main shaft 2 in an equiangular staggered manner along the axial direction. The rotor 3 and the main shaft 2 can be fixedly connected by adopting a flat key, spline fit or welding mode and the like. The initial rotating positions of the first group of rotors 3 form an included angle of 10-45 degrees in the vertical direction, and the initial positions of the two adjacent groups of rotors 3 have a difference of 45 degrees. The rotor 3 may include a fixed disk 31, 4 sliding bars 32, 4 sliding bar sleeves 33, 4 first magnets 34, and the like. Wherein the fixed disc 31 is fixed on the main shaft 2. The 4 slider bushings 33 are divided into two groups, and are radially symmetrically fixed (e.g., welded) to both end sides of the fixed disk 31. The 4 sliding rods 32 are respectively arranged on the 4 sliding rod shaft sleeves 33 in a sliding way, and two ends of the sliding rods extend beyond the fixed disc 31. Two slide bars 32 form a set. The 4 first magnets 34 are fixed to both ends of the two sets of slide bars 32, respectively. Each lever mechanism 4 corresponds one-to-one to each set of rotors 3. Specifically, the lever mechanism 4 may include a fixed fulcrum 41, a lever 42, a force application assembly 43, a magnetic member 44, and the like. The lever 42 is hinged to the fixed fulcrum 41. The force application assembly 43 and the magnetic member 44 are respectively located on both sides of the fixed fulcrum 41. The magnetic member 44 is disposed below the first magnet 34 at the initial angle θ position and magnetically repels therebetween. The starting angle theta may be between 10-45 deg.. Therefore, the repulsive force between the magnetic member 44 and the first magnet 34 causes the slider 32 to slide upward, and generates a rotational moment on the rotor 3. The force application assembly 43 generates a periodic downward acting force, the magnetic member 44 moves upward due to the lever action to be close to the first magnet 34, and a repulsive force is generated due to the magnetic repulsion between the magnetic member 44 and the first magnet 34, and the repulsive force drives the rotor 3 to rotate, so that the spindle 2 outputs power. The torque of the novel permanent magnet power machine can be increased through the lever mechanism 4, and the applicability of the novel permanent magnet power machine is greatly improved.

In the present embodiment, the magnetic member 44 is a permanent magnet. It should be understood that the magnetic member 44 may also be an electromagnet.

In this embodiment, the force application assembly 43 may include a second magnet 431 and an electromagnet 432, and the second magnet 431 and the magnetic member are respectively fixed on both ends of the lever 42 at both sides of the fixed fulcrum 41. The electromagnet 432 is fixed above the second magnet 431 and magnetically repulses therebetween. The electromagnet 432 is energized with a periodic current to generate a periodic downward force with the second magnet 431. It should be understood that the force application assembly 43 may be other structures such as a pneumatic cylinder, an oil cylinder, or an electric push rod. Preferably, the distance between the second magnet 43 and the fixed fulcrum 41 is greater than the distance between the magnetic member 44 and the fixed fulcrum 41, so that the rotor 3 can be rotated by a small magnetic force, thereby achieving a large power output.

Preferably, the rotors 3 of each set are spaced apart by an intermediate spacer sleeve to avoid interference of the rotors 3 with each other as they move axially on the main shaft 2.

In addition, the novel permanent magnet power machine can also comprise 8 position sensors 6, and the position sensors 6 are fixed on the second magnet 43. Each position sensor 6 is for detecting whether the first magnet 34 is located at the start angle θ position. When the first magnet 34 is at the initial angle θ position, the force applying assembly 43 generates a downward force (i.e., the electromagnet 432 is energized), and when the first magnet 34 is away from the initial angle θ position, the electromagnet 432 is de-energized and the lever 42 returns to the initial position. The position sensor 6 may be a hall sensor or the like.

Second embodiment

The present embodiment is different from the first embodiment only in the rotor structure. As shown in fig. 4, in the present embodiment, the rotor 3 'may include a fixing seat 31' and 8 radial bars 32 'fixed (e.g., welded or screwed) on the fixing seat 31'. The fixed seat 31' is fixed on the main shaft 2. Adjacent radial bars 32' are spaced 45 apart. Each radial rod 32 'is terminated by (e.g., welded or threaded) a first magnet 34'.

Third embodiment

The present embodiment is different from the second embodiment only in the structure of the first magnet. As shown in fig. 5 and 6, in the present embodiment, the rotor 3 "may include a fixed seat 31" and 8 radial bars 32 "fixed (e.g., welded or screwed) to the fixed seat 31". The fixed seat 31 "is fixed (e.g., welded or screwed) to the main shaft 2. Adjacent radial rods 32 "are spaced 45 apart. The first magnet 34 "is slidably mounted on the radial rod 32". That is, the first magnet 34 "may slide along the radial rod 32" during rotation, causing an increase in torque.

It should be understood that the number and shape of the first magnets 34, 34', and 34 "are not limited to the illustrated embodiment. The first magnets 34, 34' and 34 "may also be spherical, hemispherical, rectangular parallelepiped, or square, etc. Likewise, the number of rotors 3 and lever mechanisms 4 is not limited to the embodiment shown, but may be designed according to the desired output.
