Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, specifically to a high-efficiency, high-magnetic drive motor for new energy vehicles. Background Technology

[0002] As a crucial alternative to traditional gasoline-powered vehicles, the efficiency and reliability of the drive system are key technical indicators for new energy vehicles. Currently, most mainstream new energy vehicles adopt pure electric or fuel cell drive solutions, with the drive motor typically powered directly by the battery or fuel cell. However, this direct power supply method has some limitations: First, the battery's output voltage and power may fluctuate due to load changes, leading to unstable drive motor operation and affecting vehicle acceleration smoothness and energy efficiency; second, under high-load scenarios such as rapid acceleration or hill climbing, the battery's instantaneous discharge capacity is limited, potentially causing insufficient power or a sudden voltage drop, shortening battery life. Furthermore, existing drive systems often lack effective energy buffering and voltage stabilization mechanisms, making it difficult to cope with the power demands under complex road conditions.

[0003] To improve drive efficiency, some solutions attempt to introduce auxiliary power generation units, such as using an internal combustion engine to drive a generator to charge the battery (as in range-extended electric vehicles). However, these systems are complex in structure, have many transmission links, suffer significant energy losses, and cannot achieve rapid response. Meanwhile, although ordinary UPS systems can provide voltage stabilization, they are mostly used for stationary equipment and are not deeply integrated with the vehicle drive system, resulting in large size and low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency magnetic drive motor for new energy vehicles. By integrating the high-efficiency magnetic motor, generator, adapter, UPS and drive motor in series, the efficient transmission of mechanical power and the stable supply of electrical energy are achieved, thereby optimizing the vehicle driving process.

[0005] To achieve the above objectives, this invention provides the following technical solution: a high-efficiency, high-magnetic drive motor for new energy vehicles. This drive motor system comprises five core components: a high-magnetic motor, a generator, an adapter, a UPS, and the drive motor itself. These components are electrically connected to form an energy conversion chain. The high-magnetic motor serves as the initial power source, generating mechanical rotational force that directly drives the generator. The generator converts the received mechanical energy into electrical energy, supplying current to the adapter. The adapter adjusts the format and parameters of the electrical energy to meet the requirements of subsequent equipment. The UPS acts as a buffer and stabilizer, ensuring a smooth flow of electrical energy to the drive motor. The drive motor ultimately converts the electrical energy into mechanical power, propelling the vehicle. The entire system design emphasizes energy efficiency, with all components working collaboratively to achieve multiple conversions from mechanical energy to electrical energy, ultimately serving the vehicle's propulsion.

[0006] Furthermore, the connection between the high-powered magneto and the generator utilizes a rigid shaft for direct coupling, a design that eliminates the need for intermediate transmission devices such as belts or gears. The rotors of the high-powered magneto and the generator are mounted on the same axis, ensuring a short and efficient mechanical power transmission path. This coaxial arrangement reduces energy loss and vibration risks, making power transmission more direct and reliable. This rigid connection improves system responsiveness, enabling rapid torque transfer during vehicle startup, while also simplifying maintenance by reducing the number of moving parts.

[0007] Furthermore, the generator outputs three-phase AC power during operation. This current form is suitable for long-distance transmission but may require adjustment to match downstream components. The adapter internally contains conversion circuitry that rectifies the three-phase AC power into DC power and performs preliminary filtering to eliminate noise and interference in the current. The filtering stage uses passive components to smooth the waveform, ensuring that the output power meets the UPS input standards. This conversion process emphasizes compatibility, enabling the power generated by the generator to be safely utilized by downstream equipment while improving the power quality of the entire system.

[0008] Furthermore, the adapter integrates a voltage conversion module that dynamically adjusts the voltage level based on the characteristics of the input electrical energy. For example, when the generator outputs a high voltage, the conversion module can reduce it to the UPS's operating range; conversely, it can boost the voltage to avoid energy waste. Voltage conversion is achieved through semiconductor switching circuits, emphasizing efficiency and stability. This design ensures that electrical energy flowing between different components will not cause equipment damage due to voltage mismatch, thereby enhancing the overall compatibility and reliability of the system.

[0009] Furthermore, the UPS is equipped with an energy storage unit and a voltage regulator circuit. The energy storage unit, typically composed of a battery pack, can provide temporary backup power when generator power is interrupted. The voltage regulator circuit monitors the output voltage in real time through a feedback mechanism and adjusts it when fluctuations occur to maintain a stable power supply. This configuration allows the system to maintain continuous operation in the face of external interference, such as during vehicle acceleration or deceleration, the UPS can smooth the power output and prevent the drive motor from malfunctioning due to voltage surges.

[0010] Furthermore, the drive motor adopts a permanent magnet synchronous motor structure, with permanent magnets embedded in its rotor. When current is applied to the stator, a rotating magnetic field is generated, achieving efficient torque output. This motor is directly connected to the vehicle's transmission system, and the frequency and amplitude of the input current are adjusted by an electrical controller to precisely control the speed and torque. This design enables the drive motor to respond quickly and adapt to different vehicle driving conditions, such as smooth acceleration or steep incline. Simultaneously, the permanent magnet structure reduces energy loss and improves drive efficiency.

[0011] Furthermore, the system components are connected in series via shielded cables and dedicated connectors. The cables are wrapped with a metal shielding mesh to prevent external electromagnetic interference from affecting signal transmission. All electrical connections use secure interfaces to ensure reliable contact. This wiring method emphasizes safety and interference resistance, ensuring smooth energy flow between the high-powered motor, generator, adapter, UPS, and drive motor, while simplifying installation and maintenance procedures.

[0012] Furthermore, when the vehicle starts, the high-powered magneto is first energized and runs, generating mechanical power to drive the generator to rotate. The generator then outputs electrical energy, which is adjusted via an adapter and sent to the UPS for stabilization. Finally, the electrical energy supplies the drive motor, enabling it to smoothly accelerate the vehicle. This process emphasizes timing coordination to ensure that each component is activated sequentially, avoiding startup shock. The system design makes the transition from a stationary state to motion smooth, improving driving comfort.

[0013] Furthermore, a current detection function is installed on the connection line between the adapter and the UPS, using sensors to monitor the power flow in real time. The detected data is fed back to the control unit, and when the current exceeds a safe threshold, the system triggers protection mechanisms, such as automatically cutting off the circuit or current limiting. This design prevents overload risks, extends equipment lifespan, and ensures stable power transmission.

[0014] Furthermore, the output shaft of the drive motor is mechanically connected to the vehicle wheels via a coupling. The coupling allows for a certain degree of misalignment compensation, reducing mechanical stress. The drive motor receives vehicle control signals (such as acceleration or braking commands) and adjusts its current parameters to change the output power, thereby achieving forward, reverse, and braking functions. This direct drive method improves transmission efficiency and makes the vehicle's operation responsive.

[0015] This invention provides a high-efficiency, high-magnetic drive motor for new energy vehicles, which has the following advantages: 1. This technology achieves highly efficient transmission of mechanical power through a direct rigid shaft connection between the high-power magneto and the generator. The rotors of the high-power magneto and the generator are coaxially arranged, completely eliminating intermediate transmission links (such as gears or belts), thus avoiding frictional losses and energy losses found in traditional transmission systems. This design ensures that mechanical energy is transferred to the generator with almost no loss, improving electrical energy conversion efficiency and significantly enhancing the overall system's energy utilization. This efficient power transmission provides the vehicle with strong and stable power output, especially during acceleration and hill climbing, maintaining smooth power delivery and reducing energy waste. Simultaneously, the compact structure and absence of intermediate components reduce system maintenance requirements, enhance reliability, and extend the service life of critical components. This efficient transmission not only improves vehicle performance but also supports long-term stable operation, aligning with energy-saving and environmentally friendly design principles.

[0016] The adapter component plays a crucial role in the system, converting the three-phase AC power generated by the generator into DC power and performing preliminary filtering and voltage regulation. This process ensures power quality and compatibility, enabling smooth power supply to the subsequent UPS and drive motors. The voltage conversion module inside the adapter can flexibly adjust the input voltage level to match the operating range of different components, avoiding efficiency losses or equipment failures caused by voltage mismatch. Through a sophisticated filtering circuit, the adapter eliminates harmonics and noise in the AC power, providing clean DC power and ensuring the stability and smoothness of the power supply. This strong power adaptability allows the system to adapt to various operating conditions, such as voltage fluctuations or load changes, improving the adaptability and reliability of the entire vehicle. Furthermore, it ensures high-efficiency power conversion, reduces energy loss, and provides a continuous power foundation for the vehicle.

[0017] UPS units significantly improve system power supply stability through their energy storage devices and voltage regulation circuits. When generator power supply anomalies (such as interruptions or fluctuations), the UPS can use its energy storage unit to replenish power in a timely manner and maintain stable output voltage, ensuring uninterrupted vehicle operation. The voltage regulation circuit monitors voltage levels in real time and makes fine adjustments to prevent sudden voltage drops or over-voltages, thereby protecting sensitive components from damage. This design enhances system robustness, enabling vehicles to maintain smooth operation under acceleration, deceleration, or sudden load changes, avoiding driving discomfort or performance degradation caused by power instability. High power supply stability also reduces the risk of equipment failure, extends system life, and improves driving safety. Through the buffering effect of the UPS, the system can cope with short-term power shortages, ensuring continuous power supply and meeting the high standards of reliable power required by new energy vehicles.

[0018] The drive motor employs a permanent magnet synchronous structure, allowing for easy adjustment of speed and torque via electrical control to meet diverse driving needs. The permanent magnet synchronous motor features rapid response and high efficiency; combined with advanced control algorithms, it enables precise power output adjustments, allowing drivers to select different modes (such as economy or sport) based on road conditions or personal preferences. This control method eliminates the need for complex mechanical devices, achieving smooth power changes solely through electronic signals, thus enhancing vehicle handling and adaptability. Flexible control not only enhances the driving experience but also optimizes energy utilization, such as reducing torque at low speeds to save energy or providing maximum power at high speeds. Furthermore, electrical control reduces the use of mechanical components, lowering system weight and maintenance costs, and improving overall reliability. This convenient control mechanism enables the vehicle to flexibly handle various driving scenarios, increasing user satisfaction.

[0019] The system incorporates a current detection and protection mechanism between the adapter and the UPS, enabling real-time monitoring of power flow and automatic triggering of protection in overcurrent situations, thus enhancing operational safety and reliability. Current sensors continuously monitor the current value in the circuit; upon detecting an anomaly (such as overload or short circuit), the protection circuit immediately activates, cutting off power or limiting current to prevent equipment damage or escalation of faults. This proactive safety design effectively prevents potential risks such as overheating or electrical fires, ensuring the safety of the system and personnel. The protection mechanism is integrated with the vehicle control system, enabling rapid response and smooth handling, avoiding driving interruptions. High operational safety reduces the probability of accidents, extends equipment life, and meets stringent automotive safety standards. Simultaneously, real-time monitoring provides data feedback, supporting preventative maintenance and further enhancing system stability and reliability. This reliable design enables the vehicle to operate safely in various environments, improving overall performance. Attached Figure Description

Generator 2 then begins operation, converting mechanical energy into three-phase alternating current. This energy is immediately transmitted to interface 3, which converts the three-phase alternating current into direct current and performs preliminary filtering and voltage adjustment to perfectly match the input requirements of UPS 4. After processing by the energy storage unit and voltage regulator circuit within UPS 4, extremely stable power is output directly to drive motor 5. This drive motor, employing a permanent magnet synchronous structure, precisely responds to the driver's acceleration commands through electrical control, smoothly merging the vehicle into urban traffic. Throughout the commute, the system monitors the power supply in real time via the current detection function between interface 3 and UPS 4, ensuring safety.

Throughout the entire process, the vehicle achieves zero-emission and pollution-free operation, protecting the fragile ecological environment of the scenic area. Simultaneously, due to the absence of the roar and vibration of traditional internal combustion engines, the vehicle operates exceptionally quietly, enhancing the tourist experience. Scenic area staff do not need to build charging facilities, eliminating the need for the effort of maintaining charging stations. The sightseeing vehicle can operate continuously around the clock; its "environmentally friendly, energy-saving, and pollution-free" characteristics are highly compatible with the concept of green tourism, providing tourists with a comfortable and tranquil sightseeing service while conserving significant limited resources.

[0027] Example 4: Urban Logistics and Distribution Application In the logistics and transportation sector, this technology provides an efficient solution for green urban delivery. Delivery vehicles require multiple starts, stops, and loading / unloading operations daily, placing extremely high demands on the reliability and economy of the power system. During system operation, the generator 2, driven by a high-powered motor 1, continuously generates electricity. The electrical energy is adjusted through the voltage conversion module of the adapter 3 to ensure constant compatibility with the UPS 4. Even when frequent acceleration and deceleration cause power fluctuations, the energy storage unit of the UPS 4 can instantly replenish power, ensuring uninterrupted power output from the drive motor 5. This efficient energy utilization significantly reduces operating costs per kilometer. Compared to traditional fuel vehicles, it achieves zero emissions, complying with urban environmental regulations; compared to pure electric vehicles, its continuous power generation capacity eliminates the need for mid-journey charging, greatly improving delivery efficiency. With this technology, logistics fleets not only reduce operating costs but also contribute to the development of green logistics, achieving a win-win situation for both economic and environmental benefits.

The generated electricity undergoes a series of processes: the adapter 3 handles conversion and filtering, the UPS 4 ensures stable voltage, and finally drives the drive motor 5 to operate smoothly. Because the power comes from the system's internal circulation, the vehicle has an extremely long range, sufficient to handle the shuttle mission throughout the day, eliminating the need for charging during operational breaks. Its quiet operation avoids interfering with classroom teaching, and its zero-emission feature protects campus air quality. For students and faculty, this shuttle bus based on a high-powered, high-efficiency drive motor provides a convenient, comfortable, and green travel service, reflecting the campus's leading awareness in promoting sustainable transportation and serving as a successful demonstration of environmentally friendly and energy-saving technologies.
