Description

Technical Field

[0001] The present invention relates to the technical field of motor pair-drag platform testing, and in particular to a motor pair-drag platform testing system using organic working medium cooling. Background Art

[0002] Most traditional motors use air cooling and / or water cooling to dissipate the heat generated by the motor's operation. Compared to air cooling and / or water cooling, motors using organic fluid cooling are filled with organic fluid during operation, and the motor relies on this internal organic fluid for cooling, eliminating the need for external cooling.

[0003] In order to cool the motor using an organic working fluid, a system that can circulate the organic working fluid is required. This system can deliver uncooled organic working fluid into the motor and extract the cooled organic working fluid from the motor, thereby achieving the circulation of the organic working fluid. If the motor is not in this circulation system and needs to be operated or tested and evaluated for performance, the motor cannot dissipate heat, resulting in the motor being unable to operate, making testing and performance evaluation impossible. Therefore, a test system is required to enable motor testing and performance evaluation to be completed within this system. Summary of the Invention

The computer is connected to the detection instrument and the four-quadrant frequency conversion unit respectively. The detection instrument and the four-quadrant frequency conversion unit are both connected to the test motor and the companion test motor. The detection instrument is used to detect and collect target performance parameters of the test motor, and the detection instrument also uploads the target performance parameters to the computer. The four-quadrant frequency conversion unit drives the motor under test and the accompanying motor under test under computer control, and adjusts the working state of the motor under test and the accompanying motor under test according to the test needs, so that the motor under test and the accompanying motor under test switch between the motoring state and the generating state. The motor under test and the accompanying motor are connected together through a coupling. The organic working fluid cooling unit is connected to the tested motor and the accompanying tested motor through input pipes respectively, and the organic working fluid cooling unit is also connected to the tested motor and the accompanying tested motor through output pipes respectively.

[0006] Furthermore, the tested motor and the accompanying tested motor are two identical motors of the same model.

[0008] Furthermore, the organic working medium cooling unit includes a cooler, an input pipe is connected to the output end of the cooler, and an output pipe is connected to the input end of the cooler.

[0009] Furthermore, it also includes a control cabinet, which is connected to the organic working fluid cooling unit. The control cabinet is used to control the organic working fluid cooling unit so that the output, input and delivery speed of the organic working fluid by the organic working fluid cooling unit are maintained within the target delivery range, so that the test motor and the accompanying test motor are kept within the preset temperature range.

[0010] Furthermore, the control cabinet is also used to upload cooling data to the computer, and the cooling data includes the output, input, conveying speed and temperature of the organic working fluid at each moment.

For example, the connection between A and B can be either a direct connection between A and B or an indirect connection between A and B through one or more other electrical components.

[0022] like Figure 1-Figure 2As shown, this embodiment provides a motor pair drag platform test system using organic working fluid cooling, including a control cabinet 1, an organic working fluid cooling unit 2, an input pipe 3, an output pipe 4, a test motor 7, a coupling 6, a companion test motor 5, a detection instrument 8, a four-quadrant frequency conversion unit 9 and a computer 10. The computer 10 is connected to the detection instrument 8 and the four-quadrant frequency conversion unit 9 respectively. The detection instrument 8 and the four-quadrant frequency conversion unit 9 are both connected to the test motor 7. The detection instrument 8 is used to detect and collect target performance parameters of the test motor 7. The detection instrument 8 also uploads the target performance parameters to the computer 10. The computer 10 analyzes and evaluates the received target performance parameters. The evaluation result represents the test result, that is, the evaluation result is all or part of the test result.

[0023] Under the control of the computer 10, the four-quadrant frequency conversion unit 9 drives the test motor 7 and the accompanying test motor 5, and adjusts the working state of the test motor 7 and the accompanying test motor 5 according to the test requirements, so that the test motor 7 and the accompanying test motor 5 are switched between the motoring state and the generating state to complete the test of the test motor 7 and the accompanying test motor 5.

[0024] The motor under test 7 and the accompanying motor under test 5 are connected together through a coupling 6 .

[0025] The tested motor 7 and the accompanying tested motor 5 are two identical motors, and two motors of the same model can be used.

[0026] Exemplarily, a motor sealing structure is also included, and the motor sealing structure is used to seal the tested motor 7 and the accompanying test motor 5 to prevent leakage of organic working fluid.

[0027] Control cabinet 1 is connected to an organic working fluid cooling unit 2. Organic working fluid cooling unit 2 is connected to the test motor 7 and the accompanying test motor 5 via input pipes 3. This pumps an organic working fluid for cooling the test motor 7 and the accompanying test motor 5 through the input pipes 3. The organic working fluid serves as a cooling medium. Organic working fluid cooling unit 2 is also connected to the test motor 7 and the accompanying test motor 5 via output pipes 4. This pumps the heated organic working fluid (i.e., the organic working fluid becomes hot after cooling the test motor 7 and the accompanying test motor 5) out through the output pipes 4 and returns it to the organic working fluid cooling unit 2.

[0028] Input pipe 3 and output pipe 4 form a circulation pipeline, allowing the pre-cooled organic working fluid to be input into the test motor 7 and the accompanying test motor 5. The cooled organic working fluid is then output from the test motor 7 and the accompanying test motor 5 and returned to the organic working fluid cooling unit 2, thus achieving the recycling of the organic working fluid. This closed organic working fluid circulation reduces the cost of replenishing the cooling medium (i.e., the organic working fluid). When used in a motor production line, it can save the company's annual operation and maintenance costs.

[0029] Exemplarily, the organic working fluid cooling unit 2 includes a cooler, an input pipe 3 is connected to the output end of the cooler, and an output pipe 4 is connected to the input end of the cooler, so that the organic working fluid in the cooler can be transported to the test motor 7 and the accompanying test motor 5 through the input pipe 3, and the organic working fluid in the test motor 7 and the accompanying test motor 5 is input into the cooler through the output pipe 4, thereby realizing the circulation of the organic working fluid.

[0030] The control cabinet 1 is used to control the organic working fluid cooling unit 2 so that the output, input and delivery speed of the organic working fluid by the organic working fluid cooling unit 2 are maintained within the target delivery range, so that the tested motor 7 and the accompanying test motor 5 are maintained within the preset temperature range, that is, the test system is maintained at the set temperature.

[0031] The control cabinet 1 can also upload cooling data to the computer 10 . The cooling data includes data such as the output amount, input amount, conveying speed, and temperature at various times of the organic working fluid.

[0032] Exemplarily, the control cabinet 1 is a PLC control cabinet 1 .

[0033] This test system is applicable to motors used in organic working fluid environments with various types of bearings, including traditional bearings, air bearings, and magnetic bearings.

[0034] For example, the organic working fluid used as the cooling medium can be a low-boiling-point, high-heat-capacity organic working fluid, such as Freon. Compared to conventional air cooling and / or water cooling, the use of a low-boiling-point, high-melting-point organic working fluid can significantly improve the heat conduction efficiency, ensuring that the temperature rise of the test motor 7 and the accompanying test motor 5 is reduced under continuous high-load conditions. That is, compared to the temperature rise of air-cooled and / or water-cooled motors, the temperature rise of this embodiment is lower and reduced, thereby significantly improving the output power density and operating stability of the test motor 7 and the accompanying test motor 5, allowing motor testing to be performed in a safe and controllable environment.

[0035] The four-quadrant variable frequency generator set 9 and the pair-drag test architecture can realize two-way energy feedback, shorten the system response time to millisecond level, improve the test accuracy, and accurately simulate the dynamic characteristics of the motor under complex working conditions.

[0036] The use of compatible and standardized PLC control cabinet 1, four-quadrant frequency conversion unit 9 and detection instrument 8 reduces the investment in customized components, lowers installation costs, supports the rapid expansion and upgrade of motor production lines, and realizes modular integrated design.

[0037] The present invention also has the following beneficial effects: 1. Enhanced stability and reliability Enhanced stability and reliability rely on an intelligent temperature control system and sealing structure. This intelligent temperature control system is implemented through a PLC control cabinet 1 equipped with a multi-parameter adaptive algorithm. The PLC control cabinet 1 can adjust the working fluid flow and pressure in real time, keeping temperature fluctuations within ±1°C and preventing motor performance degradation caused by thermal stress.

[0038] Different motor models require different seals for their sealing structure. When deploying this test system on a mass production line, pneumatic or hydraulic devices can be used instead of screws to assist in sealing the motor, improving testing efficiency.

[0039] 2. Intelligent operation and control Intelligent operation and control are reflected in full-process automation, data visualization, and remote management. The computer-based integrated control platform enables one-button start and stop, parameter self-tuning, and fault diagnosis, achieving full process automation, reducing manual intervention by 80% and shortening test cycles by 50%.

[0040] Data visualization and remote management are equipped with detection instruments8 for multi-dimensional data collection, which can support real-time energy efficiency analysis and cloud data synchronization, and improve remote monitoring and maintenance efficiency by 70%.

[0041] 3. Environmental friendliness and scalability Environmental friendliness and scalability are reflected in its green and multi-scenario adaptability. This environmental friendliness is achieved through the use of non-toxic, biodegradable, and environmentally friendly organic refrigerants, reducing carbon emissions by 45% compared to traditional cooling systems and complying with ISO 14000 environmental management system requirements. Multi-scenario adaptability is achieved through the system's flexible configuration of refrigerant type, pipeline layout, and control logic, enabling scalable high-power motor testing across multiple fields.

[0042] 4. Security risk control Safety risk control is reflected in the multiple safety protection mechanisms. Specifically, by integrating three-level linkage protection for over-temperature, over-voltage, and leakage, the fault shutdown response time is reduced to less than 50ms, and the system safety meets the SIL-2 level standard.

[0043] Through the above-mentioned technical advantages, this test system not only solves the pain points of traditional test platforms such as low energy efficiency, high cost, and extensive control, but also makes breakthroughs in intelligence, environmental protection, and multi-industry adaptability, providing a cost-effective integrated solution for motor R&D and quality verification.

[0044] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the scope of protection of the present invention.
