Description

Technical Field

[0001] The present invention relates to the technical field of motor systems, and in particular to a high-efficiency energy-saving motor system and a method for using the same. Background Art

[0002] A high-efficiency, energy-saving motor system is an integrated power system that achieves efficient recycling of mechanical and electrical energy through mechanical energy storage, multi-unit coordinated power generation, and intelligent dynamic control. Its core goal is to significantly reduce energy consumption through structural optimization and closed-loop energy management, while also improving energy conversion efficiency and system stability.

[0003] The kinetic energy generated by existing motor systems during braking or no-load is mostly dissipated through resistors or stored in batteries, resulting in a low energy recovery rate. In addition, battery energy storage has charging and discharging losses and life attenuation problems. Traditional multi-motor systems use parallel or independent power supply modes and lack a dynamic energy distribution mechanism, resulting in some motors being overloaded and some being idle when the load is uneven. In addition, the flywheel energy storage system has large speed fluctuations due to insufficient inertia of the single-layer flywheel or poor rigidity of the shaft connection, which cannot meet the requirements of high-precision equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-efficiency and energy-saving motor system with the advantages of high efficiency and energy saving, which solves the problems of low energy recovery efficiency and easy waste of energy in the use of existing motor systems, as well as poor coordination among multiple units, which makes it difficult to meet different usage scenarios.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a high-efficiency energy-saving motor system, comprising:

[0006] A flywheel energy storage module, which consists of a flywheel, a long journal assembly, and a rear flange. The long journal assembly includes a connecting rod journal and a balance bar crank, and is used to store initial mechanical kinetic energy and transfer it to the generator through a belt.

[0007] A generator group, comprising at least two generators distributed around the flywheel axis, each generator being connected to the flywheel via a belt to convert mechanical kinetic energy into electrical energy;

[0008] Embedded motor group, the embedded motor group consists of a running drive shaft, a sleeve shaft, a short shaft head and a collection layer. The running drive shaft is disconnected from the middle and embedded in the short shaft head. The end face of the short shaft head is fixedly connected to the sleeve shaft. A collection layer is set inside the sleeve shaft to transmit electric energy. The two ends of the running drive shaft are connected to the motor, which engages with the output end of the generator through a belt to drive the two half-shafts to rotate synchronously.

[0009] The circulating transmission network uses nylon ropes to connect multiple generator groups in a perforated structure, forming a closed loop link. The electricity generated by the generator group is distributed to adjacent generator groups through the collection layer to maintain the continuous operation of the flywheel;

[0010] Dynamic stability module: The dynamic stability module controls the kinetic energy output fluctuation within a preset threshold by adjusting the flywheel's balance bar crank and the engagement depth of the sleeve shaft and the short shaft head.

[0011] As a preferred high-efficiency and energy-saving motor system of the present invention, the flywheel is a double-layer coaxial flywheel structure, the surface of the outer flywheel is provided with annularly distributed weight-reducing holes, and the inner flywheel is rigidly connected to the running active shaft neck through the balance bar crank of the long shaft neck group.

[0012] As a preferred embodiment of the high-efficiency and energy-saving motor system of the present invention, the number of generators in the generator group is 3-6, and the belt transmission ratio between the generator and the flywheel is 1:1.2-1:1.5.

[0013] As a preferred embodiment of the high-efficiency and energy-saving motor system of the present invention, the connecting end surface of the sleeve shaft and the short shaft head is provided with a wedge-shaped tooth groove, and the end of the short shaft head is embedded in the sleeve shaft tooth groove and fixed by a hydraulic locking member.

[0014] As a preferred embodiment of the high-efficiency and energy-saving motor system of the present invention, the collection barrier is composed of an inner copper conductive sheet and an outer epoxy resin insulation layer, and the conductive sheet is electrically connected to the output end of the generator.

[0015] As a preferred high-efficiency energy-saving motor system of the present invention, the surface of the nylon rope is coated with a carbon fiber braided layer, and after the nylon rope passes through the punched holes, both ends are connected to the running drive shaft of the adjacent motor group through a tension regulator.

[0016] As a preferred embodiment of the present invention, a high-efficiency and energy-saving motor system further includes a PID controller connected to the dynamic stability module, which is used to monitor the flywheel speed in real time and adjust the engagement depth of the sleeve shaft and the short shaft head so that the kinetic energy fluctuation value is ≤5%.

[0017] As a preferred embodiment of the high-efficiency and energy-saving motor system of the present invention, the motors at both ends of the operating active shaft are AC / DC dual-purpose motors, and the output ends of the motors are directly connected to external load equipment through couplings.

[0018] As a preferred high-efficiency energy-saving motor system of the present invention, the system is integrated into the chassis of a vehicle, and the flywheel energy storage module is linked with the brake energy recovery system to convert the braking kinetic energy into flywheel mechanical energy storage.

[0019] A method for using a high-efficiency energy-saving motor system comprises the following steps:

[0020] S1. System initialization: The motor of the flywheel energy storage module is driven by an external power source to accelerate the flywheel to the rated speed. The flywheel speed threshold and the kinetic energy fluctuation allowable range are set to ≤5% through the PID controller.

[0021] S2, kinetic energy storage and conversion: The flywheel offsets the centrifugal force through the balance bar crank of the long shaft neck group, driving the generator group to generate electricity. The electrical energy is transmitted to the operating drive shaft of the embedded motor group through the collection layer;

[0023] S4, dynamic stability control, monitors the flywheel speed in real time through the PID controller, adjusts the engagement depth between the sleeve shaft and the stub shaft head, and makes the kinetic energy fluctuation value ≤5%;

[0024] S5. Load power supply switching: According to the external load requirements, the AC / DC dual-purpose motor is controlled to automatically switch to AC or DC power supply mode.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention improves the efficiency of converting mechanical energy into electrical energy through the optimization of the double-layer coaxial flywheel structure and belt transmission ratio of the flywheel energy storage module. The design of the weight-reducing hole reduces the inertial resistance of the flywheel and shortens the acceleration time of the flywheel. The closed-loop link of nylon ropes in series is combined with the carbon fiber braided layer to achieve mixed transmission of mechanical energy and electrical energy, reduce the loss of power distribution, and the dynamic tension regulator balances the link tension in real time to avoid energy transmission interruption. The sustainable operation time of the system is increased. The PID controller controls the kinetic energy fluctuation value by adjusting the engagement depth of the sleeve shaft and the short shaft head, thereby reducing the response time.

[0027] 2. The balance bar crank of the present invention offsets the centrifugal force of the flywheel, reduces the vibration amplitude of the shaft system, and extends the life of the bearing. The wedge-shaped tooth grooves and hydraulic locking design of the sleeve shaft and the short shaft head improve the shear strength of the connection end and reduce the transmission slip rate. When the kinetic energy fluctuation is detected, the system automatically cuts off the high-risk link and triggers brake energy recovery to avoid equipment damage. The AC / DC dual-purpose motor supports 220V / 380V and 48V / 72V outputs, and is suitable for industrial equipment, household appliances and vehicle batteries. The power supply compatibility is improved. The flywheel and brake energy recovery system are linked, the brake kinetic energy recovery rate is improved, and the vehicle endurance is increased. The broken shaft and sleeve shaft structure of the embedded motor group can achieve quick disassembly and assembly, shorten maintenance time, and reduce annual maintenance costs.
