The invention aims to solve the problems of large load fluctuation, obvious vibration and insufficient operation stability of the input end of the traditional single-rotor generator. According to the technical scheme, through reverse rotation of coaxial double rotors, two paths of electromagnetic resistance moments form a mutually-abutting and mutually-contained mechanical equilibrium state in the structure, transmission of the resistance moments to an input shaft is reduced, the fluctuation of an input end load in a no-load and full-load power generation state is small, and the method is only used for compensating inherent loss of a system. The whole machine adopts a hybrid transmission mechanism to realize synchronous reverse rotation of double rotors and provide magnetic buffering and vibration reduction, and adopts a voltage and current comparison adjusting mechanism to realize dynamic balance of two paths of power generation output, so that two paths of electromagnetic resistance moments are always balanced and aligned, and the system stability and the operation stability are improved. The method can be used for wind power generation, hydroelectric generation, vehicle-mounted power generation and other scenes.

Description

Technical Field

[0001] This invention belongs to the field of generator technology, specifically relating to a torque self-balancing generator structure based on the reverse rotation of coaxial dual rotors to achieve internal mechanical alignment of electromagnetic resistance torque and suppression of input load fluctuations. Background Technology

[0002] In traditional single-rotor generators, the electromagnetic resistance torque acts entirely on the input shaft during power generation. This results in significant fluctuations in the input load with the output power, leading to noticeable vibration, high shaft load, and insufficient operational stability. Existing dual-rotor generators primarily focus on increasing power density, failing to achieve stable input load control. They also lack sufficient transmission synchronization, damping and vibration reduction capabilities, and the ability to balance and adjust the two outputs, making it difficult to meet the demands of efficient, stable, and long-life industrial applications. Summary of the Invention

[0003] This invention discloses a coaxial dual-rotor counter-rotating torque self-balancing generator. By rotating the coaxial dual rotors in opposite directions, the two electromagnetic resistance torques form a mechanical balance state of mutual opposition and mutual restraint within the structure, reducing the transmission of resistance torque to the input shaft. This results in smaller fluctuations in the input load under no-load and full-load power generation conditions, and the generator is only used to compensate for the inherent losses of the system.

[0004] The whole machine adopts a hybrid transmission mechanism to realize the synchronous reverse rotation of the two rotors and provide magnetic buffering and vibration reduction. It adopts a voltage and current comparison adjustment mechanism to realize the dynamic balance of the two power generation outputs, ensuring that the electromagnetic resistance torques of the two circuits are always balanced and aligned, thereby improving the system stability and smooth operation.

[0005] This invention conforms to the laws of electromagnetic induction and the law of conservation of energy; the solution is feasible, manufacturable, and mass-producible.

[0006] Specific facilities and methods

[0007] This generator is based on the coaxial dual rotors rotating in opposite directions to form two electromagnetic resistance torques. The internal mechanics of these two torques counteract each other, reducing the net resistance torque transmitted to the input shaft. This results in smaller load fluctuations at the input end and only compensates for inherent system losses such as magnetic loss, iron loss, and mechanical friction loss.

[0008] The hybrid transmission mechanism ensures synchronous reverse rotation of the two rotors through rigid transmission, and absorbs transmission shock and reduces vibration and noise through magnetic buffering; the voltage and current comparison and adjustment mechanism collects the output voltage and current parameters of the two channels in real time and dynamically adjusts the load distribution to keep the electromagnetic resistance torque of the two channels always balanced and aligned, thereby improving the stability and reliability of operation. The two sets of power generation windings are independent of each other and can be connected in series or in parallel to output according to application requirements. The whole machine has a compact structure and high space utilization, making it suitable for industrial production and multi-scenario applications. Beneficial effects

[0009] The reverse rotation of the dual rotors achieves internal mechanical suppression of the electromagnetic resistance torque, resulting in smaller load fluctuations at the input end and improved operational stability. Hybrid transmission combines rigid synchronization with magnetic buffering, resulting in reliable transmission, low impact, low vibration, and extended service life. Voltage and current comparison adjustment ensures balanced output from both paths, stable torque alignment, and strong system robustness; Input shaft load and fatigue wear are reduced, and the overall service life of the machine is extended; It features a compact structure, high power density, and wide applicability. The plan is scientifically rigorous, conforms to the law of conservation of energy, and is manufacturable, implementable, and mass-producible.
