Description

Technical Field

[0001] This invention belongs to the field of generators, and more specifically, relates to a motor that achieves relative angular velocity adjustment by rotating the stator relative to the housing. Background Technology

[0002] A generator typically consists of the following parts:

[0003] The stator is the stationary part of the generator, typically consisting of an iron core and windings. Its main function is to provide a magnetic field or conductor for inducing current. The rotor is the rotating part of the generator, usually composed of conductors and an iron core. The rotor rotates through mechanical drive (such as a steam engine or water turbine), generating an electromotive force (EMF). The magnetic field can be generated using permanent magnets or electromagnets (provided by an external power source). A magnetic field is essential for the generator to produce voltage. A commutator (in the case of a DC generator) or rectifier is used to change the direction of the current, converting the output current into usable direct current (DC) or alternating current (AC).

[0004] During operation, the generator converts mechanical energy into electrical energy. When the generator's rotor (usually driven by external machinery) starts to rotate, it cuts magnetic lines of force in the stator windings. According to Faraday's law, the relative motion between the conductors on the rotor and the magnetic field generates an induced electromotive force (voltage). This voltage depends on the magnetic field strength, the rotor's rotational speed, the length of the conductors, and the relative motion between the rotor and the stator. The induced electromotive force causes a current to be generated in the conductors, which is received by the stator windings and output through an external circuit.

[0005] For traditional generators, their power generation depends on rigid conditions such as input power, rotor speed, magnetic field strength, and the number of stator and rotor windings. If you want to increase power generation, you need to upgrade the above hardware standards. However, this not only increases costs, but also fails to meet the market demand for energy saving and efficiency improvement. Summary of the Invention

[0006] To address the above deficiencies, this invention provides a motor that achieves relative angular velocity adjustment through relative rotation between the stator and the housing, comprising a power generation system and a power conversion system;

[0007] The power generation system includes a stator housing for fixing the stator and rotor, with an external generator and a power conversion system respectively connected to both ends of the stator housing.

[0008] The power conversion system converts the clockwise rotation of the stator housing driven by the stator into counterclockwise rotation through a gear set, and drives the rotor to rotate synchronously and in the opposite direction relative to the stator through the rotor shaft.

[0009] It also includes a cable tray mounted on the power generation system and the power conversion system. The cable tray allows the circuits in the power generation system to pass through. The ends of the power generation system and the power conversion system that are far apart are in contact with the slip ring mechanism at the power generation system and the power conversion system through fixed carbon brushes and conduct electricity.

[0010] Furthermore, the stator housing includes a housing, a front cover, and a rear cover. The stator is fixed to the inside of the housing by a number of fixing screws, and the two ends of the rotor are fixed to the rear cover and the front cover by male and female buckles and four-sided locks, respectively.

[0011] The four-sided lock has a bearing installed in the middle for the rotor shaft to rotate and connect. The rotor shaft passes through the bearing and the reserved hole in the front cover and extends to the conversion system.

[0012] A gear shaft is fixed to the outer wall of the front cover. The gear shaft has a channel for the rotor shaft to pass through, and the gear shaft is connected to the conversion system.

[0013] The rear cover is connected to an external generator via a welded rear end shaft.

[0014] Furthermore, the power conversion system includes a gearbox, and a gear set is provided on the side of the gearbox near the power generation system. The gear set consists of, from the inside out, a driving gear, three planetary gears, internal and external gears, and two small transmission gears that are meshed together.

[0015] The drive gear is fixedly connected to the gear shaft. All three planetary gears are rotatably connected to the inner partition of the gearbox via rotating shaft I and mesh with the gear shaft. All three planetary gears simultaneously mesh with the inner teeth of the inner and outer gears. The inner and outer gears are rotatably connected to the rotating groove opened in the inner partition via a rotating ring welded on the back. All two small transmission gears are rotatably connected to the inner partition via rotating shaft II and mesh with the outer teeth of the inner and outer gears.

[0016] An intermediate gear is rotatably mounted in the middle of the other side of the inner partition. Two large transmission gears are meshed on both sides of the intermediate gear and are rotatably mounted on the inner partition. The inner ring of the intermediate gear is fixedly connected to the outer surface of the rotor shaft.

[0017] Furthermore, stator housing supports are fixed to the left and right ends of the housing respectively, and the wire harness is mounted on the two stator housing supports and the top of the gearbox.

[0018] The rear end shaft is tubular, and the rear end shaft is provided with a bracket position for passing through and supporting on the stator housing bracket, a pulley position for connecting to the belt of an external generator, and two slip ring positions for installing slip rings. A voltage regulating slip ring and a generator slip ring I are installed at the slip ring positions. A wire hole is also provided between the two slip ring positions. One end of the voltage regulating wire and the generator wire at the rotor passes through the rear cover and exits from the wire hole and the end of the rear end shaft, respectively, and is electrically connected to the voltage regulating slip ring and the generator slip ring, respectively.

[0019] The rotor shaft is also tubular, and two wires at the rotor pass through one end of the gearbox through the rotor shaft and are electrically connected to the generator slip ring II installed on the outer surface of the rotor shaft.

[0020] The front cover and the rear cover are respectively mounted with carbon brushes adapted to the bottom voltage regulating slip ring, generator slip ring I and generator slip ring II through a fixing bracket at their respective ends. The carbon brushes on both sides are electrically connected through the wiring inside the cable tray to complete the electrical circuit.

[0021] Furthermore, the two ends of the male and female buckles are welded and fixed to the arc-shaped grooves opened on the inner wall of the rear cover, and the end of the male and female buckles near the rotor shaft is provided with a shaft groove for rotation, and a voltage regulator is installed on the side of the male and female buckles near the rear cover.

[0022] Furthermore, the inner wall of the four-sided lock has four grooves arranged in a ring, and each groove is fixed to the front cover by bolts.

[0023] Furthermore, the rotor shaft is also fixed with fan blades on the outer surface of the stator and the four-sided lock, and two sets of heat dissipation holes are provided on the surface of the housing.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] Compared to traditional methods of improving rigid conditions, this equipment transmits the power output from the stator to the rotor shaft via a gear set, and then from the rotor shaft to the rotor. The gear set reverses the direction of the output, allowing the rotor and stator to rotate simultaneously at the same speed but in opposite directions. This increases the number of times the magnetic lines of force are cut, thereby increasing the power generation. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example

[0036] like Figures 1 to 4 As shown, this embodiment provides a motor that achieves relative angular velocity adjustment through relative rotation between the stator and the housing, including a power generation system and a power conversion system;

[0037] The power generation system includes a stator housing 5 for fixing the stator 3 and the rotor 4. The stator housing 5 includes a housing 51, a front cover 54 and a rear cover 55. The stator 3 is fixed to the inside of the housing 51 by two sets of eight fixing screws 59. The two ends of the rotor 4 are fixed to the rear cover 55 and the front cover 54 by male and female buckles 58 and four-sided locks 53, respectively.

[0038] After the two ends of the male-female buckle 58 are inserted into the two arc-shaped grooves opened in the inner wall of the rear cover 55, they are welded and fixed (the arc-shaped grooves are about 5 cm away from the side of the rear cover 55). The male-female buckle 58 has a shaft groove for rotation at the end near the rotor shaft 41. A voltage regulator is installed on the side of the male-female buckle 58 near the rear cover 55 (the voltage regulator is electrically connected to the voltage regulating slip ring 11 after passing through the wire hole at the rear cover 55). The center of the four-sided lock 53 is inlaid with a bearing 56 for the rotor shaft 41 to pass through. The inner wall of the four-sided lock 53 has four slots distributed in a ring. Each slot is fixed to the front cover 54 by bolts. The rotor shaft 41 passes through the bearing 56 and the reserved hole opened in the front cover 54 in sequence and extends to the conversion system 2.

[0039] Meanwhile, a gear shaft 57 (with an oil seal inside) is fixed to the outer wall of the front cover 54. The gear shaft 57 has a channel for the rotor shaft 41 to pass through. The gear shaft 57 is also connected to the conversion system 2.

[0040] Therefore, for the power generation system, the rear cover 55 is connected to the external generator through the welded rear end shaft 9, while the front cover 54 is connected to the power conversion system 2 through the rotor shaft 41 and the gear shaft 57, thereby realizing the transmission connection between the three.

[0041] In detail, the rear shaft 9 is tubular, and the rear shaft 9 is provided with a bracket position for passing through and supporting on the stator housing bracket 8, a pulley position for connecting with the belt of the external generator, and two slip ring positions for installing slip rings. A voltage regulating slip ring 11 and a generator slip ring 12 are installed at the slip ring positions. A wire hole 10 is also provided between the two slip ring positions. Two wires at the stator 3 pass through the rear cover 55 and pass out from the wire hole 10 and the end of the rear shaft 9, respectively, and are electrically connected to the voltage regulating slip ring 11 and the generator slip ring 12.

[0042] The rotor shaft 41 is also tubular. Two wires at the rotor 4 pass through the rotor shaft 41, pass through one end of the gearbox 21, and are electrically connected to the generator slip ring II13 installed on the outer surface of the rotor shaft 41.

[0043] In addition, the rotor shaft 41 is fixed with fan blades 52 on the outer surface of the stator 3 and the four-sided lock 53. The surface of the housing 51 is provided with two sets of heat dissipation holes 6 (round holes or square holes are acceptable) to achieve good heat dissipation and ensure stable operation of the equipment.

[0044] like Figures 5 to 6 As shown, the power conversion system 2 includes a gearbox 21. A gear set is provided on the side of the gearbox 21 near the power generation system. The gear set consists of a drive gear 22, three planetary gears 23, an inner and outer gear 24 and two small transmission gears 25 that are meshed together, from the inside to the outside.

[0045] The driving gear 22 is fixedly connected to the gear shaft 57. The three planetary gears 23 are rotatably connected to the inner partition of the gearbox 21 through the rotating shaft I and mesh with the gear shaft 57. The three planetary gears 23 mesh with the inner teeth of the inner and outer gears 24 at the same time. The inner and outer gears 24 are rotatably connected to the rotating groove opened in the inner partition through the rotating ring 28 welded on the back. The two small transmission gears 25 are rotatably connected to the inner partition through the rotating shaft II and mesh with the outer teeth of the inner and outer gears 24. Thus, the function of the driving gear 22 rotating can drive the entire gear set to rotate.

[0046] An intermediate gear 27 is rotatably mounted on the middle of the other side of the inner partition via a rotating shaft. It should be noted that the intermediate gear 27 and the driving gear 22 are relatively independent and not connected. Two large transmission gears 25 are meshed on both sides of the intermediate gear 27 and are rotatably mounted on the inner partition via a rotating shaft. Similarly, the large transmission gear 25 and the small transmission gear 25 are also relatively independent. The inner ring of the intermediate gear 27 is fixedly connected to the outer surface of the through end of the rotor shaft 41 so that the intermediate gear 27 can drive the rotor shaft 41 to rotate synchronously.

[0047] The working principle is as follows: the clockwise rotation of rotor 4 is converted into counterclockwise rotation through a gear set, which drives stator housing 5 to rotate. This causes stator 5 and rotor 4 to rotate at the same speed, synchronously, and in opposite directions (instead of the traditional stationary state), thereby increasing the number of magnetic lines of force cut and thus increasing power generation. In the experiment, using the stator and rotor of a 3kW generator, the power generation was 4080 watts when the speed reached 2300 rpm, and 4860 watts when the speed was adjusted to 2600 rpm, showing a significant improvement in power generation efficiency.

[0048] It also includes a cable tray 7 mounted on the power generation system and the power conversion system. The cable tray 7 is mounted on the top of the two stator housing supports 8 and the gearbox 21. The two stator housing supports 8 are fixed to the left and right ends of the housing 51, respectively. The ends of the front cover 54 and the rear cover 55 that are far apart from each other are respectively equipped with carbon brushes 14 that are compatible with the bottom voltage regulating slip ring 11, the power generation slip ring I12 and the power generation slip ring II13 through the fixing bracket 15. The carbon brushes 14 on both sides are electrically connected through the wiring inside the cable tray 7 to complete the electrical circuit of the entire equipment.

[0049] Alternatively, reducing the number of large transmission gears 26 can reduce the power required for transmission, thereby achieving energy saving and efficiency improvement.

[0050] It should be noted that the structure described in this invention can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the description and drawings of this invention, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this invention.
