Description

TECHNICAL FIELD

[0001] The present application relates to the field of energy recycling, in particular to a positive feedback energy recycling system. BACKGROUND

[0002] In the prior art, when the rotor of a three-phase motor increases the mechanical resistance, it will increase the input supply of greater current and power through magnetic interaction to maintain the speed of the blocked rotor. This driving system is not the most energy-saving system, especially during motor starting, running process and blocking.

[0003] To solve the problem of energy saving of the existing three-phase motor, the present application develops a positive feedback energy recycling system to increase the mechanical resistance of the rotor by increasing the differential speed between the rotating space magnetic field and the rotor winding to obtain induced energy, and then all the positive feedback is sent back to the input end through three-phase bridge rectification, so as to realize high-efficiency energy saving by increasing the positive feedback energy power when the mechanical resistance is greater, and solve the current market gap. SUMMARY

[0004] The present application aims to provide a positive feedback energy recycling system, which is a new thinking, a new method and a more energy-saving driving energy recycling solution.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: A positive feedback energy recycling system, comprising an encapsulation shell, an internal system and an external device, the internal system comprising an inverter, a frequency converter, a three-phase bridge rectification module, a farad capacitor, a diode, a copper wire, a rectification group and a terminal, the external device comprising a battery and a stator and rotor three-phase winding motor, the internal system comprising an inverter, a frequency converter, a three-phase bridge rectification module, a farad capacitor, a diode, a rectification group, a battery and a stator and rotor three-phase winding motor are electrically connected through copper wires. Advantages

[0006] The positive feedback energy recycling system has the following advantages compared with the existing three-phase motor: 1. The high-speed rotating space magnetic field of the motor stator generates three-phase induced voltage in the rotor winding, which is rectified by the three-phase rectifier bridge. The rectified voltage needs to be higher than the output voltage of the battery pack 1 power supply before the current starts to flow out to generate induced force, thereby avoiding damage to the motor caused by high starting current during motor starting and avoiding high energy consumption during motor starting, and improving the motor starting characteristics.

[0007] 2. The motor stator high-speed rotating space magnetic field generates three-phase induced voltage in the rotor winding, which is rectified by the three-phase rectifier bridge and then fed back to the input end A1-A3 of the inverter to form a closed loop, at this time the input and the output of the positive feedback are both with the same load, according to the maximum power transmission theorem, when Z L =Z S , the load obtains the maximum power transmission, thereby improving the circuit load characteristics and realizing the maximum power output of the electric energy transmission.

[0012] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0013] As Figs. 1-3As shown, a positive feedback energy recycling system, including a packaging shell 8, internal system and external device, the internal system includes inverter (60V / 220V) 1, frequency converter (three-phase 380V) 2, three-phase bridge rectifier module (MDS100A / 1600V) 3, 3 farad capacitor (480V) 4, 5 diode (1600V / 110A) 5, copper wire 9, rectifier group 10 and terminal 11. External device includes battery (60V) 6, stator and rotor three-phase winding motor (YZR series) 7; inverter (60V / 220V) 1, frequency converter (three-phase 380V) 2, three-phase bridge rectifier module (MDS100A / 1600V) 3, 3 farad capacitor (480V) 4, 5 diode (1600V / 110A) 5, battery (60V) 6, stator and rotor three-phase winding motor 7 and rectifier group 10 are electrically connected through copper wire 9, rectifier group 10 includes 4 diodes (1600V / 110A) and 2 farad capacitors (480V); inverter input includes A1, A2 and A3, A1, A2 and A3 are provided with 1 farad capacitor (480V) and 1 diode (1600V / 110A); the packaging shell 8 can cover the internal system, and each stator and rotor three-phase winding motor 7 is composed of stator winding and rotor winding.

[0014] In use: The battery (60V) 6 current input to the inverter (60V / 220V) 1, the inverter (60V / 220V) 1 will input current to the rectifier group 10, the rectifier group 10 provides the frequency converter (three-phase 380V) 2 with starting power supply, the frequency converter (three-phase 380V) 2 provides three-phase power supply for external three-phase stator and rotor winding motor 7 after starting operation, the high-speed rotating space magnetic field is generated in the motor stator, the high-speed rotating space magnetic field will generate three-phase induced voltage in the rotor winding, at this time, the motor rotor winding generates three-phase induced voltage open circuit no load, which is equivalent to a three-phase transformer with open circuit secondary side, without induction magnetic force to drive the motor rotor to rotate. When the rotor output three-phase induced voltage is rectified by the three-phase bridge rectifier module (MDS100A / 1600V) 3, the positive feedback is sent back to the inverter (60V / 220V) input A1-A3 to form a closed loop cycle, thereby forming a positive feedback power energy recycling power supply system.

[0015] Wherein the adjustment frequency converter (three-phase 380V) 2 (with function) output frequency has the function of continuously increasing and decreasing the frequency, the adjustment frequency converter (three-phase 380V) 2 output frequency makes the motor stator rotating space magnetic field speed continuously increase, the three-phase induced voltage in the rotor winding will continuously increase, after the three-phase bridge rectifier module (MDS100A / 1600V) 3 rectification, the positive feedback is sent back to the inverter (60V / 220V) 1 input end A1-A3 current continuously increases, the motor rotor rotating speed also continuously increases, when the positive feedback is sent back to the inverter (60V / 220V) 1 input end A1-A3 current increases to approximately equal to the current input by the battery (60V) 6, that is, A1≈A3, A2≈2A1≈2A3, at this time, the motor rotor rotating speed is far less than the stator space magnetic field rotating speed, the mechanical resistance received by the motor rotor at this time almost does not affect the power input of the battery (60V) 6, at this time, the input system current is equal to the positive feedback current, and the double current is input into the motor system, at this time, the whole circuit system is in the lowest energy consumption state, and the output mechanical power remains unchanged, and the resistance received by the rotor almost does not affect the input power.

[0016] In summary, under the condition that the frequency of the adjustment frequency converter is lower than the non-resonant frequency, the present application solves the technical problem that the existing three-phase motor rotor increases the mechanical resistance by increasing the input current and power through magnetic interaction. The mechanical resistance received by the rotor is increased by the difference between the rotating space magnetic field and the rotor winding, and then the induced energy is fed back to the input end through the three-phase bridge rectifier, so that the greater the mechanical resistance, the greater the positive feedback energy power, thereby realizing the technical effect of high efficiency and energy saving.

[0017] Under the condition that the frequency of the adjustment frequency converter is approximately equal to the resonant frequency, the input system current is equal to the positive feedback current, and the double current is input into the motor system, at this time, the whole circuit system is in the lowest energy consumption state, and the output mechanical power remains unchanged, and the resistance received by the rotor almost does not affect the input power.

[0018] The technical features of the above-mentioned embodiments can be combined arbitrarily, in order to make the description simple, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0019] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
