[0002] A permanent magnet drive is a device that utilizes the interaction between permanent magnets to achieve energy conversion and transfer. It boasts advantages such as high efficiency, simple structure, and convenient maintenance, and has been widely used in industrial production, transportation, and other fields. The permanent magnet drive generates driving force through a permanent magnet motor, which then transmits the power to the load via gear transmission and other mechanisms, thus driving the load.

[0003] There are some shortcomings in the practical use of existing permanent magnet drive devices:

[0004] On the one hand, when the load suddenly decelerates or stops during operation, the kinetic energy stored in the drive system of traditional permanent magnet drive devices cannot be effectively recovered, but is dissipated in the form of heat, resulting in energy waste.

[0005] On the other hand, existing devices have low transmission efficiency, significant energy loss during gear transmission, and a fixed transmission ratio that cannot be adaptively adjusted according to actual working conditions, making it difficult to meet the needs of different loads.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-4 Example 1: A permanent magnet drive device with adaptive kinetic energy recovery includes a base 1. A permanent magnet motor 2 is fixedly connected to the top outer wall of the base 1 by screws. A three-phase winding 11 is provided inside the permanent magnet motor 2. A three-phase cable 3 is fixedly connected to the outer wall of one end of the three-phase winding 11. A pin 4 is provided on the outer wall of one end of the three-phase cable 3.

[0029] The base 1 is the fundamental support component of the entire device, used to fix and support other components. The permanent magnet motor 2 is fixed to the top outer wall of the base 1 by screws and is the core power component of the device. The three-phase winding 11 inside the permanent magnet motor 2 is wound around the inner wall of the motor stator 23 and connected to the three-phase cable 3. One end of the three-phase cable 3 is provided with a pin 4 for connecting to an external power source or load. When an external power source supplies power to the three-phase winding 11 through the pin 4 and the three-phase cable 3, the three-phase winding 11 generates a rotating magnetic field, driving the motor rotor 24 to rotate, thereby outputting power.

[0030] In the second embodiment, a drive gear 5 is provided on the outer wall of one end of the permanent magnet motor 2, and a driven gear 6 meshes on the outer wall of the drive gear 5.

[0031] The drive gear 5 is mounted on the output shaft 25 of the permanent magnet motor 2 and rotates as the output shaft 25 rotates. The driven gear 6 meshes with the drive gear 5 and is mounted on the drive shaft 7. When the drive gear 5 rotates, it drives the driven gear 6 to rotate through meshing, thereby transmitting power to the drive shaft 7. The drive gear 5 and the driven gear 6 are housed inside the gearbox 12, which is fixed to the end sleeve 22 of the permanent magnet motor 2 by screws, serving to protect the gears.

[0032] In embodiment three, a drive shaft 7 is installed through the inner wall of the driven gear 6, and a first bevel gear 8 is fixedly connected to the outer wall of the drive shaft 7.

A gearbox 12 is fixedly connected to one side of the outer wall of one end sleeve 22 by screws, and both the drive gear 5 and the driven gear 6 are located inside the gearbox 12. The drive gear 5 is installed on one end of the outer wall of the output shaft 25.

[0033] The drive shaft 7 is installed through the inner wall of the driven gear 6 and rotates synchronously with the driven gear 6. When the drive shaft 7 rotates, it drives the first bevel gear 8 to rotate, which in turn drives the second bevel gear 9 and the driven shaft 10 to rotate through meshing, thereby transmitting power to the driven shaft 10 and realizing the transmission of power and the change of direction.

[0034] The permanent magnet motor 2 includes a housing 21 and an end sleeve 22. The housing 21 is fixedly connected to the top outer wall of the base 1 by screws, and the end sleeve 22 is fixedly connected to the outer walls of both ends of the housing 21. The permanent magnet motor 2 also includes a motor stator 23, a motor rotor 24, and an output shaft 25. The motor stator 23 is disposed inside the housing 21, the motor rotor 24 is disposed on the inner wall of the motor stator 23, and the output shaft 25 is fixedly connected to the inner wall of the motor rotor 24. The permanent magnet motor 2 also includes a stator winding 26. The stator winding 26 and the three-phase winding 11 are both wound around the inner wall of the periphery of the motor stator 23.

[0035] The outer casing 21 and the end sleeve 22 constitute the housing of the permanent magnet motor 2, protecting internal components such as the motor stator 23 and motor rotor 24. The motor stator 23 is fixed inside the outer casing 21, the motor rotor 24 is disposed on the inner wall of the motor stator 23, and the output shaft 25 is fixed on the inner wall of the motor rotor 24. When the motor rotor 24 rotates, it drives the output shaft 25 to rotate. The stator winding 26 and the three-phase winding 11 are both wound around the inner periphery of the motor stator 23. The stator winding 26 is used to generate a magnetic field, and the three-phase winding 11 is used to receive external power or output recovered electrical energy.

[0036] A first connecting plate 13 is welded to the top outer wall of the base 1, and the passive shaft 10 is rotatably connected to the inner wall of the first connecting plate 13 through a bearing. The top outer wall of the base 1 is provided with a first sleeve 14 and a second sleeve 15 that are distributed adjacently, and the first sleeve 14 and the second sleeve 15 are located on both sides of the first bevel gear 8. The drive shaft 7 is disposed through the interior of the first sleeve 14 and the second sleeve 15. The top outer wall of the base 1 is welded with a second connecting plate 16 that is distributed adjacently, and the first sleeve 14 and the second sleeve 15 are both welded to the outer wall of the second connecting plate 16.

[0037] The first connecting plate 13 is used to support and fix the passive shaft 10, ensuring the stable rotation of the passive shaft 10. The first sleeve 14 and the second sleeve 15 are used to support and guide the drive shaft 7, ensuring the stable rotation of the drive shaft 7 and reducing shaking and noise during rotation.

[0038] Working principle: First, the external power supply supplies power to the three-phase winding 11 of the permanent magnet motor 2 through pin 4 and three-phase cable 3. The three-phase winding 11 generates a rotating magnetic field, which drives the motor rotor 24 to rotate. The motor rotor 24 drives the output shaft 25 to rotate.

[0039] The output shaft 25 drives the drive gear 5 to rotate inside the gearbox 12. The drive gear 5 meshes with the driven gear 6, driving the driven gear 6 to rotate. The driven gear 6 then drives the drive shaft 7 to rotate.

[0040] When the drive shaft 7 rotates, it drives the first bevel gear 8, which is fixed on its outer wall, to rotate. The first bevel gear 8 meshes with the second bevel gear 9, which drives the second bevel gear 9 and the driven shaft 10 to rotate, thereby transmitting power to the driven shaft 10 and driving the load.

[0041] When the load suddenly decelerates or stops, the driven shaft 10 drives the second bevel gear 9 to rotate, the second bevel gear 9 drives the first bevel gear 8 and the drive shaft 7 to rotate, the drive shaft 7 drives the driven gear 6 and the drive gear 5 to rotate, the drive gear 5 drives the output shaft 25 to rotate, and the output shaft 25 drives the motor rotor 24 to rotate in the magnetic field of the motor stator 23. The three-phase winding 11 cuts the magnetic field lines to generate an induced electromotive force, and outputs electrical energy through the three-phase cable 3 and pin 4 to realize the recovery of kinetic energy.
